Instruction Manual

V6R B-Van Lithium

The B-Van is equipped with a 51.2V house battery, an alternator, alternator regulator, 3500W Inverter solar charger, and 200W of solar panels. These instructions will lay out the components and how to operate and maintain them.

Must Read Before Operating

• These instructions are for reference only, please refer to the individual product manuals for detailed instructions and data.

• Do not modify or alter the components in any way.

• Do not connect an external charger to the Lithium Battery.

• Do not alter the solar array in any way.

• Do not connect anything other than the Renogy solar blanket (optional) to the external solar connection.

• Do not attempt to charge the battery with the following conditions:
  o If the voltage difference between the min and max cell voltage is greater than 800mv.
  o If the battery total voltage is less than 32V.
  o If the max cell reads 8,000mV or similar.
  o If the min cell is under 2,000mV.

• When completing service, do not connect or disconnect any 48V DC system components while the system is ON. Verify the Lithium Battery is OFF and all charging sources:
  A. Alternator
  B. Shore Power
  C. Rooftop Solar – disconnect near battery in the ‘OFF’ position
  D. Side Solar

• For technical assistance please call Patrick Distribution Inc., 1-800-621-2278 or email renogyoem@patrickind.com

Quick Startup

• It is highly recommended that all charging sources are OFF when powering up and powering down the lithium system. (See Getting Started and Powering Down – Storage and Service sections)
• The Samkoon battery screen should be the primary screen to gather lithium battery information as it provides information directly from the battery BMS.
•  If the battery reaches 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV. The unit will need to start receiving a charge.
• When the unit is depleted below 10% SOC, this can cause the SOC% and voltage levels to be out of calibration. Recalibrate the BMS by changing the inverter parameter #9 to 54.4 and charge the unit to 100% SOC.
•  It is imperative to try to recharge the battery to 100% SOC, as this also recalibrates the BMS and balances cells.
•  The 12V Master Disconnect (Main Power) Switch must be in ‘ON’ for the unit to charge with the Alternator.
•  When charging with shore power, do NOT start the vehicle.

Storage and Cold Weather Recovery
When storing the unit during the winter months or an undetermined length of time, the BMS should be recalibrated before storage to ensure the SOC is correct and the system should be shut down following the “Powering Down – Long Storage” section. There are three different storage terms listed below, and each have their own unique specific criteria. The important part is to determine which storage method, or combination of methods suit the intended storage.

• Short Term Storage
  is defined as storage in which the battery is shut down, unused for up to one month, 30 continuous days. It is important to note that the temperature and humidity range for short term storage is greater than medium or long term storage. This is important to pay close attention to this detail because the aforementioned environmental criteria will define the maximum length of time the battery can be stored.
  1. Short Term Storage: up to 1 month, 30 continuous days
  2. Storage temperature and humidity range: -20°C to 35°C / -4°F to 95°F, 45% to 75% Relative Humidity
  3. Charge the battery to 100% SOC before putting it in storage mode
  To prepare the battery for short term storage, you can charge the battery up to up to 100% SOC, and not lower than 50% before putting it in storage mode. If the storage temperature is less than 10°C or 51°F, then it important to charge the battery to, or as close to 100% SOC.

• Medium Term Storage is defined as storage in which the battery is shut down, unused for a length of time greater than one month, 30 continuous days, and up to three months, or 90 continuous days.
  This is important to pay close attention to this detail because the aforementioned environmental criteria will define the maximum length of time the battery can be stored.
  1. Medium term storage: Greater than 1 month, 30 continuous days, and less than 3 months, 90 continuous days
  2. Storage temperature and humidity range: -10°C to 30°C / 14°F to 86°F, 45% to 75% Relative Humidity
  3. Charge the battery to 70% SOC before putting it in storage mode
  To prepare the battery for medium term storage, you can charge the battery up to 70% before putting it in storage mode. It is important to note that the environmental criteria is more stringent than the short term storage, and if this criteria is not able to be met, then you cannot store the unit for the extended length of time.

• Long Term Storage is defined as storage in which the battery is shut down, unused for a length of time greater than three months, 90 continuous days, and no longer than six months, or 180 continuous days. The suggested SOC before storage is 50%. Storing battery at full charge will cause more capacity loss (permanent) overtime comparing to 40% to 50% SOC. This is important to pay close attention to this detail because the aforementioned environmental criteria will define the maximum length of time the battery can be stored.
  1. Long term storage: Greater than 3 months, 90 continuous days, and less than 6 months, 180 continuous days
  2. Storage temperature and humidity range: 0°C to 30°C / 32°F to 86°F, 45% to 75% Relative Humidity
  3. Charge the battery to 50% SOC before putting it in storage mode

To prepare the battery for long term storage, you can charge the battery up to up to 50% before putting it in storage mode. It is important to note that the environmental criteria is more stringent than the short term storage, and if this criteria is not able to be met, then you cannot store the unit for the extended length of time.
Following Long Term Storage, the lithium battery will need be cycled and calibrated to reflect the correct SOC% and to ensure optimal performance.

Storage Temperature@ 45-75% Relative
Humidity| Short Term: 0-30 Days| Medium Term: 30-90| Long Term:  90-180 Days
---|---|---|---
35°C / 95°F
30°C /  86°F| NOT RECOMMENDED FOR STORAGE
0°C  / 32°F
-10°C / 14°F
-20°C / -4°F| RECALIBRATE BMS &STORE BATTERY
@ 50-100%| RECALIBRATE BMS & STORE BATTERY
@ 70%| RECALIBRATE BMS & STORE BATTERY @ 50%

NOT RECOMMENDED FOR STORAGE
Important Notes:

1. In order to avoid a cold and dead battery, it is highly recommended to utilize the Short Term Storage  method. Once a month, operate the battery system including discharging/charging the system and verifying the battery SOC is between 50 to 100%.
2. At the lowest allowed storage temperature -20°C/-4°F, the dischargeable capacity is about 70% of the rated capacity of the battery. Essentially, you are losing 30% of the amp hours. Instead of 210aH, it will be closer to 147aH.
3.  With the battery shut down and below 0°C /32°F in storage mode, the self-consumption rate of the lithium cell is about 3% per month.
4.  The maximum storage duration is 6 months.
5.  Long Term storage is NOT RECOMMENDED when:
   a. Below freezing temperature. This will minimize the lithium battery voltage loss during storage and increase the recovery time caused by lower temperatures.
   b. Temperatures are extreme over 60°C /140°F.
   • Storing the battery outside of these environmental parameters: (-20°C to 35°C / -4°F to 95°F, 45% to 75% Relative Humidity) will trigger the low temperature cut off and the battery will be un-usable, and can cause permanent damage. If exposure to environmental criteria outside of the aforementioned parameters is needed please contact RENOGY at: renogy- oem@patrickind.com

51.2V 210Ah Lithium Battery

• DO NOT over-charge or over-discharge the battery.
•  DO NOT discharge the battery at high temperatures above 140°F (60°C).
• Battery Operational Parameters:

0°C~55°C
Discharge Temperature Range| -4°F~140°F / -20°C~60°C
Storage Temperature Range| -4°F~95°F / -20°C~35°C
Operation Relative Humidity| 5%~95%

• Switch Operation:
  o The battery can be turned on or off with the Self-Locking Switch and Self- Resetting Switch. For the first time use, press down the Self-Locking Switch and long press the Self-Resetting Switch for approximately 5-10 seconds to turn on the battery. There will be a series of clicks which are completing self-checks on the battery. After the last click, the COM light should begin to flash Orange and the Self-Resetting Switch can be released.
  o Prior to long periods of storage, press the Self-Locking Switch again to turn off the battery.  hen the battery is off, it has a low self-discharge rate and can hold the charge for a longer
  period of time.
  o If the battery is in protection mode, it can be restarted by long pressing the Self-Resetting Switch for 3~5 seconds. After restarting, the battery will automatically run the self-check program and release the protection mode if the recovery conditions have been reached.

• Heating Function Operation
  o The normal operation of the heating function requires a stable charge current greater than 8A.  he heating function will start operating automatically once the battery temperature drops below 41°F (5°C) and stop operating automatically once the battery temperature rises above 50°F (10°C).
  NOTE: The heating function will not be able to operate normally if the unit is not connected to shore power, and the charger setting #28 is not greater than 5A. The solar array is not large enough to preheat the battery.

• Charging Battery
  During the standard charging process, the battery is first charged at a constant current via the 51.2V Input/output Terminals until the battery voltage reaches between 54.0V and 54.8V. The standard charging process is considered complete when the charge current is less than 4.2A. However, leaving the battery on float will continue to balance the battery cells and will not damage the battery. The standard charging process normally takes 7 hours. The battery should be charged to 54.4V to recalibrate the BMS which adjusts the SOC meter, and keeps it close to specifications. This should be done periodically, or as needed. Setting number 9 on the inverter charger may be adjusted between 54.0V and 54.8V to accomplish your specific usage, and then to recalibrate the BMS when needed. Safe charging requires battery temperatures within normal operating temperatures. If the heating function is unable to work normally, battery temperatures above 32°F (0°C) is also required for the

• Discharging Battery
  During the standard discharging process, the battery is discharged via the 51.2V Input/output Terminals until the battery voltage reaches 48.0V. Safe discharging requires battery temperatures between -4°F (-20°C) and 140°F (60°C). In order to keep all charging options available, the battery should be charged once it reaches 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV. Discharging the battery below the Total Voltage or Minimum Cell Voltage can lead to an under voltage fault, which will require the battery to be recovered and limits the charging options to shore power only.
  • Recovery Process
  To begin the recovery process, connect the RV to an external 120VAC (up to 30A) power source and ensure that the inverter/charger power switch is in the “ON” position. The battery will begin “clicking”. The Total Voltage, Cell Voltages and SOC will slowly increase. The Warning or Protection Recovery points will need to be reached to clear (see the BMS Warnings & Protections).

• Battery Maintenance
  The battery needs to be maintained above 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV. When any of the parameters are met, a recharge cycle needs to take place. This can be completed by either connection to 120VAC 30A source or starting the engine to allow the engine driven alternator/generator to recharge the battery. o If the battery is not recharged, under-voltage disconnects will take place. The high voltage (51.2V circuit – inverter/charger, engine driven alternator and cabin A/C) and the low voltage (12V circuit – Firefly, interior/exterior lighting, and water pump) will stop functioning when the protection level is achieved (see the BMS Warnings & Protections below).
  o If the lithium battery is disconnected for under-voltage protections, recharging with the engine driven alternator/generator cannot take place. It is vital to always keep the battery above 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV to avoid the loss of functionality and recharging options.

• Cold Weather Recovery
  Note that in cold weather, when the cell temperature drops below 10°C (50°F), the unit will need connected to shore power. The self-heat process may take 15-20 minutes to activate and begin warming the cell temperature enough to re- charge the battery bank. The warming process could take up to one hour or longer. The inverter/charger will charge at 8A to heat the battery, and once the minimum cell temperature reaches 5°C the charging contactor will close, and full charging will begin.

• Cycling the Battery
  On batteries which have been in storage for longer than (6) months, the state of charge percentage (SOC%) may read 100% by default. It is recommended to cycle and calibrate the battery to reflect the correct SOC% and to ensure optimal performance.
  1. Power on the battery.
  2. Use the solar inverter to discharge the battery until it disconnects. Large loads will help you achieve this faster such as turning on the air conditioner.
  a. Battery with 137.3.1 Firmware = 2600mV on the lowest cell or 41.6V
  b. Battery with 137.3.13 Firmware – 3000mV on the lowest cell or 48V
  3. Once the battery reaches this point, the Samson will power off and the battery will disconnect from the circuit.
  4. To begin the recovery process, connect the RV to an external 120VAC (up to 30A) power source, and ensure that the inverter/charger power switch is in the “ON” position. The battery will begin “clicking” and the Samkoon will turn back on. The SOC% will slowly increase. It is imperative to try to recharge the battery completely so that it undergoes a complete cycle. NOTE: It is recommended to shut down any non-critical loads to allow the battery to recharge quicker.

• Calibrating New or Replaced Batteries
  When the unit is depleted below 10% SOC, this can cause the SOC% and voltage levels to be out of calibration. If the SOC% is incorrect or out of sync, then it is important to charge the battery completely to resynchronize calibration.
  1. Ensure the battery is ON.
  2. Ensure that the remote inverter/charger power switch is in the “ON” position. The button should be pushed in to power and green light showing.
  3. Change the inverter setting #9 to 54.4V.
  4. Connect the unit to an external 120VAC (up to 30A) power source.
  5. The battery will begin “clicking” and the Samson will turn on. It is imperative to charge the battery to 100% completely.
  6. Change the inverter setting #9 to 54.0V.

Cell Imbalance
Cell imbalance refers to a condition in which individual cells within a battery module have variations in their electrical characteristics, such as voltage, capacity, or internal resistance. These variations can lead to unequal performance among cells, potentially impacting the overall performance, safety, and longevity of the battery system.
To catch cell imbalances, we need to observe them at a different reference point and not when the batteries are fully charged. Fully charged LFP cells have an acceptable cell voltage differential that can grow due to chemical variability, aging of the cell, and balancing, and be perceived as widest in the fully charged process but not necessarily indicative of a cell imbalance. Therefore, you also won’t find balancing occurring during the end charge process. Balancing occurs in the recharging process.
When reviewing the Samkoon screen, there are several parameters which will require a mandatory stoppage of this inspection and repair procedure. Immediately contact Patrick Distribution (1-800-6212278 or email renogy- oem@patrickind.com) for approval to replace the lithium battery.
WARNING: Do not attempt to charge the battery with the following conditions:

• If the voltage difference between the min and max cell voltage is greater than 800mv.
• If the battery total voltage is less than 32V.
•  If the max cell reads 8,000mV or similar.
• If the min cell is under 2,000mV.

When determining cell imbalance, the charge source should be disconnected and the battery idle to observe the actual voltage difference gap between the maximum volt cell and the minimum volt cell. Cell imbalance is determined when the differential has grown beyond 300mV.
Note: At 500mv cell differential the Samkoon will report a Level 1 warning and at 800mv cell differential the Samkoon will report a Level 2 protection. Only when the cell differential has been
closed to below 300mv will the error on the Samkoon clear. 

• Clearing Cell Imbalance
  Clearing cell balancing requires having a stable charge source and prolonging the charge process so that balancing may take effect. Balancing cannot be carried out if there are any overvoltage warnings and will also not be carried out if the total charging current reaches 0, indicating the battery is fully charged.

The balancing algorithm is only carried out during charging, triggered when both the following conditions are met:

1. Single cell voltage reaches 3.4V
2. The voltage difference between cells is above 60mV.

When the balancing starts, the cell(s) with high voltage will be discharged at 50mA. The balancing will be ON for 1 sec, then OFF for 1 sec. As long as both the above conditions are met, the balancing cycle will be carried out intermittently. It can’t be a continuous process, to avoid overheating of the resistor in balancing circuit.
Cells can be balanced by the following method:

1. Review the Samkoon screen to verify the system is not any alarm state – warning or protections.

2. With the lithium system operational and clear of any faults:
   A. Discharge the system to below 53.0V.
   B. Let the battery sit idle for 10-15 minutes.
   C. Observe and note the Total Voltage, Max_Volt and Min_Volt.

3. Change inverter settings:
   A. Press SET button on Inverter to open parameter settings
   B. Press UP or DOWN and go to Parameter #9 and then press ENT button
   C. Parameter setting will begin to flash, then change to 54.0V.
   D. Press ENT button to save setting
   E. Press UP or DOWN and go to Parameter #28 and then press ENT button
   F. Parameter setting will begin to flash, then change to 5A.
   G. Press SET button to exit setting menu

4. Connect the unit to an external 120VAC (up to 30A) power source.

5. Continue to charge with shore power for an extended amount of time.
   NOTE: Dependent on the lithium battery condition, balancing may take 1-2 days.

6. To observe the cell imbalance differential gap closing, discharge the battery to the same Total Voltage in Step 2 and compare the cell differential. It should be observed that the cell differential should be closer as this cannot be seen when the battery is fully charged.
   NOTE: Repeat Steps 2-5 until the cell differential has closed completely and/or until the Cell Imbalance error has cleared.\

Battery 101
How to quickly calculate power for consumption, and recharge. There is a physical limit to the amount of stored energy, so energy must be budgeted. You can determine what each activity, or load will “cost you” in watt-hours. This will help you understand energy usage, and how to make your reserve last when a charging source in not available.
To be able to manage energy, there needs to be a basic understanding of a few mathematic equations to convert energy from one source to the same source as the battery. The first step is a basic understanding of electrical terms.
The battery is rated at 51.2VDC at 210Ah. An “Ah” is amp-hour, or a rating for battery capacity (electric charge) which means that it will supply 210 amps of current for one hour. This means that to determine the capacity that a load will consume we will need to use a few calculations to move the loads of various power sources to one value.
To make calculations easy, we will use watt-hours or Wh. Watts is a measure of power, and it’s the roduct of the current and voltage of a specific load or device, and to determine power, simply multiply the wattage (in watts) by the time it’s used (in hours). Example:
Coffee pot consumes 12.5A and it connects to the 120VAC outlet. (12.5A) x (120V) = 1500W
To determine the energy use (watt-hours) of the activity, first determine the load in watts and multiply by the time it’s used (in hours). Example: Making coffee for breakfast and the coffee pot was on for 30 minutes: Wh = (1500W) x (.5 Hours) = 750Wh
The battery has 210 Ampere Hours at 51.2VDC, or 10,752Wh of energy available at 100% SOC. Each 1% of SOC (state of charge) is equal to 2.1A at 51.2VDC, or 107.52Wh (51.2V x 2.1A). To determine current reserve capacity, in SOC% left after the usage, divide the Wh’s of usage by 107.52Wh to determine the SOC % that the activity would cost. Then you can compare that SOC percentage from the current SOC percentage to determine if you want to perform that activity. Continuing our example from above: Making coffee for breakfast and the coffee pot was on for 30 minutes:
Wh = (1500W) x (.5 Hours) = 750Wh
SOC% = 750Wh/107.52Wh = 6.98%
SOC% Cost for 30 minutes of coffee is approximately 7% SOC The display will give you current SOC%, and the aforementioned calculations can be used to determine what loads will cost in SOC, to help determine how long the current capacity can last before recharging. Recharging uses the same calculations so you simply convert the amps of charging to watt hours, then SOC%. The only difference is you add from current SOC% instead of subtract. To simplify this, a chart was comprised of typical loads and charge values, with corresponding Wh and SOC percentage are.
SOC Quick Reference for discharge: Use the chart below as a quick reference for typical load SOC percentages to subtract from current SOC percentage for discharge times, see below:

Rangy BT-2 Bluetooth Module: Pair the controller to the Renogy DC Home App to monitor your system using a smart device like a cell phone or tablet. Set custom charging parameters using User Mode and monitor your system in real time. APS-500 Alternator Regulator
The APS-500 provides control over alternator-based charging by utilizing system voltage, current monitoring and alternator and battery temperature to ensure safe and powerful charging. The APS-500 Alternator Regulator is equipped with a multi-color LED which provides a range of operational and advisory codes. The LED is visible via a waterproof bezel located on near the lower left corner of the label on the regulator’s cover.
WARNING: Turn off switches and disconnect your batteries prior to installing your APS-500 Alternator Regulator or other electrical system components. Failure to do so may cause damage or injury. Do not reconnect batteries until wiring is complete, and ensure wires are connected correctly.
There are three modes of information provided:

• Orange (Flashing) = Synced with the battery BMS
• Green = Lost communication with the battery BMS
•  Red (Flashing) = Error/Advisory mode

Should the APS-500 determine that a condition is outside of normal limits, it will display a red flashing LED pattern, followed by a series of flashes indicating the type of fault occurring. Most errors are hard-faults, indicating a condition which the APS-500 Alternator Regulator is unable to decipher and as such will shut down until corrected, in order to prevent any potential systems or battery damage. A few errors will attempt to autorestart to see if the failing condition clears (example, error low battery voltage). When a fault is detected, the APS-500 will flash the “Error” code twice, followed by a series of flashes indicating the fault/error number. Note: the LED will only indicate the most recent fault detected.

• Ignore the fast flashes.
• Start counting the number of flashes to provide you the first digit of the error code.
•  There will be a short pause.
•  Start counting the number of flashes to provide you the second digit of the error code.

In some models, the APS-500 is not easily accessible via an access panel. In these vehicles, a secondary light has been added.

Frequently Asked Questions (FAQ)

How long does it take to fully charge the Lithium Battery?

• There are a number of variables surrounding the length of time to fully charge the Lithium Battery. • The Inverter Boost Charge Voltage (setting #9) should be set to 54.0 most of the time. The system can be charged utilizing alternator, shore power and/or solar. • The battery needs to be maintained above 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV. When any of the parameters are met, a recharge cycle needs to take place. This can be completed by either connection to 120VAC 30A source or starting the engine to allow the engine driven alternator/generator to recharge the battery.

What is my Battery Operation Status?

• The battery contains a battery management system (BMS) that warns you and protects the battery from over-voltage, under-voltage, overcurrent, short circuit, high temperature, low temperature, uneven temperature, uneven voltage, and insulation fault. At the Battery Operation Status, you will find a number between 0-3. 0 = Normal (NO faults and all operating values are within normal range) 1 = Warning – message will clear when the system recovery value is reached 2 = Alarm – requires a battery restart when the system recovery value is reached 3 = Protection – requires a battery restart when the system recovery value is reached • It is important to note that a lithium battery fault may affect multiple components. By first looking at the battery monitor screen (Renogy Samkoon), it will help diagnose the root cause of the fault and allow for the fault to be corrected. Once the battery fault is corrected, all other erroneous faults will be cleared from alternator regulator. The most common faults are under-voltage, over-voltage and undertemperature. It is important to know that the severity number of the fault, which is indicated in the second bubble below the battery is a 1 (warning), 2(alarm), 3(protection). Any condition with the fault level of 1 or warning is self-recoverable, and will correct itself once the level of the waring is reduced.

How do I verify that the Lithium Battery is charging?

• On the Samkoon Screen: o Review the Top Bubble which states Charge or Discharge. o Review the Total Current - Negative Current means the system is discharging and positive current means charging.  Alternator: Depending on total voltage and other circumstances, the typical total current can range from 0-100A.  Shore Cord: Depending on total voltage and other circumstances, the typical total current can range from 0-40A.  Solar Power: Depending on total voltage and other circumstances, the typical total current can range from 0-4A. • On the Inverter Screen, review to ensure that the inverter is showing the solar and/or utility charging:

If my Lithium Battery has a fault, what do I need to do?

Refer to the BMS Warnings & Protections chart in the 51.2V 210Ah Lithium Battery section (above) for the triggering and recovery condition of each warning and protection. • Most common faults are Battery Under-Voltage, Battery Cell Over-Voltage and Charge Low Temperature. o Battery Under-Voltage or Cell Under-Voltage: plug in the shore cord to charge the lithium battery to the recovery condition. o Battery Over -Voltage or Cell Over-Voltage: remove any charging sources and utilize the 12V or 48V system to draw down the battery to the recovery condition. o Charge Low Temperature : Bring the unit inside to allow the unit to warm or warm the unit with the internal heaters by connecting the shore power, it will provide a stable charge current greater than 8A required for the self-heating function to operate normally. • NOTE: Warnings will automatically disappear and Protections will require restarting the Lithium Battery.

How do I verify my shore power is charging on the inverter?

• The Inverter remote switch must be in the ON position and the AC/INV light on the Inverter Screen must be a solid Orange light indicating the shore power is connected. • On the Renogy Inverter Remote Switch, verify that the Red light is off and/or review the Inverter Screen to see if any Inverter Faults are present. The most common faults are 03 (Battery Not Detected) and 04 (Battery Under-voltage).

How do I verify my rooftop solar power is charging?

• There two different solar options for the Lithium System: o There are 4 50W solar panels mounted on the roof, wired in series to create a 74.4VDC 200W solar array that is connected to the 3500W 48V MPPT inverter / charger, to recharge the 51.2VDC 210 aH Lithium Ion battery. o There is a factory installed Rover Boost DC to DC charge controller connected to the factory installed external solar port to recharge the 51.2VDC 210 aH Lithium Ion battery. • The rooftop solar panels are connected to an emergency disconnect switch on the roof and a secondary disconnect switch near the inverter. There are multiple solar connections dependent on production build: • Units prior to MY2024, the solar routes through the inverter to the lithium battery. o On the inverter LCD screen, press the down button to cycle through the screens until they get to the one that shows PV Input Voltage on the left side of the screen and PV Output Current on the right side of the screen. o The PV Input Voltage must be over 60V for solar to charge from the 200W solar array on the roof. The PV Output Amps (A) charge output displays how many Amps the solar is charging. • Units built after MY2024, the solar routes through the Victron Solar Controller to the lithium battery. o Use the Victron Connect APP. The PV Input Voltage must be over 60V for solar to charge from the 200W solar array on the roof. The PV Output Amps (A) charge output displays how many Amps the solar is charging. Solar will produce about 3-5A on sunny day

Why is my Alternator not charging the battery?

• The APS-500 Voltage Regulator is the component that regulates the alternator charging by getting messages from the battery BMS. There is a light on the voltage regulator: o Orange (Flashing) = Synced with the battery BMS o Green = Lost communication with the battery BMS o Red (Flashing) = Error/Advisory mode • Should the APS-500 determine that a condition is outside of normal limits, it will display a red flashing LED pattern, followed by a series of flashes indicating the type of fault occurring. Most errors are hardfaults, indicating a condition which the APS-500 Alternator Regulator is unable to decipher and as such will shut down until corrected, in order to prevent any potential systems or battery damage. • A few errors will attempt to auto-restart to see if the failing condition clears (example, error low battery voltage). When a fault is detected, the APS-500 will flash the “Error” code twice, followed by a series of flashes indicating the fault/error number. Note: the LED will only indicate the most recent fault detected.

What needs to be done to clear Charge Low Temperature Warning and/or Protection?

• With the system shut down for long periods of storage, it is not necessary to keep the unit connected to shore power. However, shore power will need to be connected if the temperature drops below 10°C (50°F) for charging • The heat process may take 15-20 minutes to activate and begin warming the cell temperature enough to re-charge the battery bank. The warming process could take up to one hour or longer. • The inverter/charger will charge at 8A to heat the battery, and once the minimum cell temperature reaches 5° the charging contactor will close, and full charging will begin. NOTE: With the shore power connected, it is common to hear clicking and to see the shore power to connect and disconnect on the inverter. Leave the shore power connected and allow time to complete the warming process. NOTE: Once the warming process is completed, it will take additional time to charge completely.

Does my battery draw power to heat the battery in cold weather?

• The normal operation of the heating function requires a stable charge current greater than 8A. The self-heating function will start operating automatically once the battery temperature drops below 41°F (5°C) and stop operating automatically once the battery temperature rises above 50°F (10°C). • The self-heating function will not be able to operate normally if the unit is not connected to shore power, and the Inverter Maximum A/C Charging Current (setting #28) is not greater than 5A. The solar array is not large enough to preheat the battery.

What do I need to do if my battery goes into Battery Over-Voltage or Cell Over-Voltage Protection Mode?

• To begin the recovery process, disconnect any external 120VAC (up to 30A) power source and turn off the secondary solar switch. Ensure that the inverter/charger power switch is in the “ON” position. o If a Warning occurs, the message will automatically clear itself once the recovery threshold is met. o For a Protection (hard fault), the protection mode will need to be cleared by allowing the cell voltage to reach the recovery and restarting the battery. NOTE: With the new lithium battery firmware 137.3.13, the 48V side will stop operating but the 12V side will continue to work as an attempt to lower the cell voltage.

What do I need to do if my battery goes into Battery Under-Voltage or Cell Under-Voltage Protection Mode?

• To begin the recovery process, connect the RV to an external 120VAC (up to 30A) power source, and ensure that the inverter/charger power switch is in the “ON” position. o For a Protection (hard fault), the protection mode will need to be cleared by allowing the cell voltage to reach the recovery and restarting the battery. • When the unit is depleted below 10% SOC, this can cause the SOC% and voltage levels to be out of calibration, the only way to recalibrate the BMS is to charge the unit to 54.4V which will re-calibrate the SOC to 100%. NOTE: If a battery is allowed to let the minimum cell voltage to be lower than 2000mV, it is unlikely that the lithium battery can be recovered.

Why is the SOC% (State of Charge) not showing on the Firefly Screen?

• When the unit is depleted below 10% SOC, this can cause the SOC% and voltage levels to be out of calibration. • There are times when you will see that this system’s total voltage is either increasing or decreasing but the SOC% may appear to be locked on a certain percentage. The BMS (Battery Management System) can fall out of calibration over time. • When this occurs, change the inverter #9 setting to 54.4 and fully charging the battery with shore power. It will recalibrate the battery BMS. NOTE: After calibration, it is recommended to re-set Inverter setting #9 back to 54.0V.
