Features

The Lithium Series Slim 48V 2.4 kWh battery has the following features:

• Designed for use in photovoltaic applications.
• Battery Management System (BMS): The BMS system built into the battery that monitors its operation and does not allow it to work outside the bounds of the design regime (V, I).
• Expandability: The system’s accumulation capacity can be expanded by incorporating more batteries.

The standard packing list of Lithium Series Slim is as follows:

Assembly and connection
Batteries may be connected in parallel up to a maximum of 15. All batteries must be grounded. It is suggested to connect the installation ground to the rack at the same point as all battery lands.

• Connection between batteries:

  • Up to 15 batteries are allowed to be used in parallel.
  • The batteries used in parallel must be the same batch of cases with the same SOC.
  • The Voltage difference of batteries used in parallel must be within 0,5V.
  • The dimensions of parallel cable must be the same.
  • The batteries must be connected two by two with the same cable to the bus, following next scheme.
    

• Connection between battery and inverter:
  25 mm2 power cable section.
  NOTE: Each power cord can carry a maximum of 120 A, so every two batteries would need to connect a new cable to the inverter. However, if the inverter is 5 kW only with one cable it would be enough to be at the limit of the maximum current recommended.

Warning when doing a battery expansion: It is very important that in the case of connecting batteries in parallel that are not new (for example, we add a new battery to an existing system), we previously perform a voltage balancing (without load) between them to avoid overcurrents that could damage the system. As an alternative to balancing voltages, balancing can be done by equalizing the SOC of the batteries. In addition, when connecting new batteries, we must take into account that the number of batteries at the time of connection must be similar to the number of batteries that are already connected in the system. For example, if we have five batteries installed and we want to connect a new one, we must first connect the new battery with two of the five that were already in place to balance them, and then connect these three with the other three remaining batteries in the system. Batteries should always be connected in groups of similar numbers so that a large group cannot damage a smaller group of batteries at the time of connection.
There must be installed a higher power of batteries than the inverter power
The sum of batteries power must be higher than the sum of the inverters power

Configuration without communications
For those cases where the battery is intended to operate connected to an inverter without communications, it’s not necessary to select a specific configuration of the DIP switches and the batteries do not need to be connected each other with the communication cable.

Configuration with communications
Communication cable: It will be configured one way or another depending on the inverter used.

Cable configuration Hybrid Inverter Turbo Energy/ Goodwe/Solis/Growatt

• It can be used a Straight-through cable
• Connect the cable to the CAN-2 port
• Growatt inverter is connected to the RS485-3 port

Cable configuration Victron

Connect the cable to the CAN-2 port

Cable configuration Sofar

Connect the cable to the CAN-1 port

Cable configuration Voltronic

Connect the cable to the RS485-2 port

DIP switch

Each module has 4 DIP switches (Dual Inline Package) that will be configured differently according to the number of batteries will be connected

On and Off
For the connection between batteries, we need to follow the next connection procedure:

1. With all devices disconnected, we proceed to the connection of the batteries, cables between each other.
2. We connect the master battery to the inverter, both energy cable and communication cable.
3. We turn on the batteries.
4. We turn on the inverter.

To turn on the batteries, we must do it one by one. To turn them off, when turning off one, all of them will turn off at the same time.
To turn on, press the power button for 2 seconds. The BMS will start and the LCD screen light up.
To turn off the batteries, press the power button for more than 3-6 seconds.

Sleep Function
When RS485/CAN communication interruption, no charge and discharge, no button operation, 5 minutes later, the system will go into sleep mode to reduce self- consumption. In this mode, the battery power connectors still have normal battery voltage.
When the battery is in the sleep mode and meets any of following conditions, the system will quit sleep mode and wake up.

1. Charge or discharge current is detected.
2. Press the “power” button for 1 second.
3. Access communication cable (RS485/CAN).

Power down function
When any of the following conditions are satisfied, the system will go into power down mode to reduce self-consumption and protect the cells:

1. Press the “power” button for 3~6 seconds and release it;
2. The lowest cell voltage is lower than the power down voltage, and the duration reaches the power down delay time (while no charging current).

In this mode, the battery power connectors don’t have voltage.
When the battery is in the power down mode and meets any of following conditions, the battery will quit power down mode and wake up.

• Charging current is detected (charging voltage should be higher than 48 V);
• Press the “power” button for 2 seconds and release it.

LED display
The LED light on the front of the battery will indicate the State Of Charge (SOC) as shown in the following table:

Protection codes
LED Alarm
Red light: 1 flicker
Green light:
N. º flickers = protection code

This error only operates in case that not all lads are illuminated. If all lads are on, means 100% charge. If not all, means cell overvoltage

LED Alarm
Red light: 2 flickers
Green light: N. º flickers = error code

If the battery constantly runs for 30 days and its SOC has not been corrected, the discharge function will not be available until the battery is fully charged at least once and the SOC is corrected.
If we find that the battery charges and discharges but the SOC doesn’t, it might be a signal that the battery needs to be updated.

Appendix

Security instructions

1. Please read the battery instructions before use.
2. Keep the battery away from high voltage and out of reach of children.
3. In operation, the battery should be kept in the set temperature ranges (between -10ºC and 50ºC) and a humidity less than 80%.
4. During handling, be very careful to avoid bumps/falls of the battery.
5. Be careful not to touch the contacts at the same time.
6. The battery, at the end of its useful life, requires a recovery process, not disassemble it.
7. Avoid locating batteries in damp places to avoid danger.
8. When not in use for a long time, store the battery intact and let the battery be half charged. Wrap the battery with non-conductive material to avoid direct contact of the metal. Store the battery in a cool, dry place.
9. Never expose the battery to fire or water.

Safety warnings

1. Do not disassemble the batteries. The inside of the battery has a protective mechanism and a protective circuit to avoid danger. Improper disassembly will damage the protection function permanently, leaving the battery without safety conditions.
2. Never short-circuit the poles of the Battery. Avoid contact of positive and negative poles with metals.
3. Keep the batteries away from fire and extreme temperatures. Monitor the distance to thermal bulbs, stoves, etc.
4. Keep the battery away from the water. Always be careful that the battery is not located in damp places where the dew point can be reached.
5. Do not use batteries that have physical damage that may be due to falls or bumps.
6. Do not weld near the battery.
7. Overheating will result in the loss of the protective function of its life cycle, even, it could render the battery useless and in extreme cases self-ignition of the battery occurs.
8. Never connect this battery in series and connect it in parallel only with identical batteries up to a maximum number of 6.
9. If the battery has liquid leakage, avoid contact with it completely. It can be harmful to the skin, and if you touch the eyes, wash, and go to the hospital immediately for treatment.
