Battery wiring connection process

Make sure battery switch is off and battery nominal voltage meet S-BP specification before connecting battery to inverter and make sure invereter is totally isolated from PV and AC power.[4]

1. Prepare battery cables and accessories and put battery power cable through battery cover.
   Note:

2. Please use delivered accessories.

3. Battery power cable should be 25-35mm2.

4. Use Special Tool to Crimp
   Make battery terminals:

   • Strip cable coat, revealing 10mm length of metal core.
   • Use special crimper to compress battery terminal tightly.

5. Connect battery terminal onto inverter.

• For the compatible lithium batteries (LG / PYLON / BYD / GCL / DYNESS / ALPHA) connection, please visit www.goodwe.com.

Battery Protection Description
Battery will act as protective charge/discharge current limitation under any condition as below:

• Battery SOC is lower than I-DOD

• Battery voltage lower than discharge voltage

• Battery over temperature protection

• Battery communication abnormal for lithium battery

• BMS limitation for lithium battery
  When charge/discharge current limitation protection happens:

• Under on-grid mode, battery charge/discharge operation could be abnormal

• Under off-grid mode, Back-Up supply will shut down

Note:

1. Under on-grid mode, battery is protected from over discharge by DOD and discharge voltage, under off-grid mode, it is protected by only discharge voltage in priority.
2. The DOD setting of a battery prevents the inverter from discharging battery reserve power. As soon as the DOD is reached the load of building will only be supported by either PV power or from the grid. If there are continuous days when little or no battery charging occurs, the battery may continue to self-consume energy to support communications with the inverter. This behaviour is different between battery manufactures products, however, if the SOC of the battery reaches a certain level the inverter will boost the SOC back up. This protection mechanism safegurads the battery to falling to 0% SOC.

On-Grid & Back-Up Connection
An external AC breaker is needed for On-Grid connection to be isolated from grid when necessary. Below are the requirements of On-Grid AC breaker.

1. Use a separate AC break for individual inverter.
2. On AC side, the individual break should be connected before loads (between inverter and loads).

On-grid wiring connection process is as below:

Make sure inverter inverter is totally isolated from any DC or AC power before connecting AC cable.[5]

1. Prepare the terminals and AC cables according to the right table.
   Cable| Description| Value
   ---|---|---
   A| Outside Diameter| 11-12 mm
   B| Isolation section| NA
   C| Conductor wire length| 7-9 mm
   D| Conductor core section| 6 mm2

Note:

1. Neutral cable shall be blue, line cable is black or brown (preferred) and protective earth cable yellow-green.
2. For AC cables, PE cable shall be longer than N&L cables, so that if in any case the AC cable slips or is taken out, the protecting earth conductor will be the last to take the strain.

2. Put AC cable through the terminal cover in the following sequence.
   Note: Please use the terminals in the accessories box.

3. Press the six connectors on cable conductor core tightly.
   Note: Make sure cable jacket is not locked within the connector.

4. Connect the assembled AC terminals onto the inverter.
   Note: Make sure it is not connected to a wrong side.

5. Lock the cover and screw the cap on.

Declaration for back-up function
The below statement lays out manufacturer’s general policies governing the energy storage inverters of the series ES, EM, SBP, ET, EH and BH.

• For Hybrid inverters (Series ES, EM, EH and ET), the standard PV installation typically consists of the connection of the inverter with both panels and batteries. In the case where the systems are not connected to the batteries, the back-up function is strongly not advised for use. GoodWe shall not cover the standard warranty and be liable for any consequences arising from users not following this instruction.
• Under normal circumstances, the back-up switching time is less than 10 ms (the minimal condition to be considered as the UPS level). However, some external factors may cause the system to fail on Back-Up mode. As such, we recommend the users to be aware of conditions and follow the instructions as below:

1. Do not connect loads if they are dependent on a stable energy supply for a reliable operation.
2. Do not connect the loads which may in total exceed the maximum back-up capacity.
3. Try to avoid those loads which may create very high start-up current surges such as Inverter Air-conditioner, high-power pump etc.
4. Due to the condition of battery itself, battery current might be limited by some factors including but not limited to the temperature, weather etc.

Declartion for back-up loads
GoodWe S-BP inverter is able to supply a continuous 5000VA output(max 5500VA within 10s) on Back-Up side. And the inverter will shutdown when it is full loading with high ambient temperature if grid is absent.

• Accepted Back-Up loads: television, computer, fridge, fan, illumination lamps, microwave oven, electrical rice cooker and router etc.
• Unacceptable house loads for Back-Up side: air conditioner, water pump, heaters, washing machine, electromagnetic oven, compression engine, hair drier and dust cleaner etc. with high power and other loads with high inrush current at start-up.

Special adjustable settings
The inverter has field adjustable setting like tripping point, tripping time, reconnect time, active and invalid QU/PU curves etc. They can be adjusted using special firmware, please contact after-sales for the special firmware and adjustment methods. For a convenient maintenance, an SP3T switch could be installed on Back-Up and On-Grid side. Then it is adjustable to support load by Back-Up or by grid or left alone.

1. Load is supplied from Back-Up side
2. Load is isolated
3. Load is supplied from grid side

Declartion for Back-Up overload protection

Inverter will restart itself if overload protection occurs. The preparation time for restarting will extend (max one hour) if overload protection repeats. Take following steps to restart inverter immediately:

• Decrease Back-Up load power within max limitation.
• On SolarGo APP → Advanced Setting → Click “Reset Back-Up Overload History”

Confirm On-Grid connected to power gird and Back-Up to loads: polarity (L/N) are not reversed, refer to 4.2.2.
Smart Meter & CT Connection:

1. If connection between Smart Meter and CT (port 1 and 4 on Smart Meter) is OK.
   Note: After turn on AC power, the COM led on Smart Meter should be blinking.

2. Make sure CT is connected between house loads and grid. And it follows the House Grid direction on CT, refer to 4.2.3.
   Note: For three-pahse Smart Meter, please refer to 2.4.3 Smart Meter & CT Connection to check if the connection and communication of Smart Meter is OK.

Battery Settings, BMS Communication and Safety Country:
After connecting Solar-WiFi ( means the last 8 characters of the inverter serial No.), check on SolarGo APP Param to make sure battery type is right what you have installed, and Safety Country is right. If not right, please set it right in “Set”.
For lithium batteries, BMS status is “Communication OK”.

Note: If BMS Status says “NG”, then please make sure battery communication cable wiring connection and all settings are all right, refer to battery connection SOP in S-BP QUICK INSTALLATION INSTRUCTIONS.

Problems During Operation
S-BP does not start up with only battery Solution:
Make sure the voltage of battery is higher than 48V, otherwise battery cannot start S-BP up.
No discharge or output from S-BP to support loads

Possible Reason:

1. There is grid-tied inverter connected in the system, and the output power is higher than power.
2. Load is connected between gird and CT, thus the system cannot detect load power, which is supported by grid power.
3. Load power is lower than 150W, as battery will only discharge if load power is higher than 150W.
4. Smart Meter communication fails or CT connected in a wrong direction, which gives S-BP wrong data.
5. Battery is not in the condition fort discharging, such as low SOC, battery communication fail for lithium batteries etc.

Solution:

1. Make sure communication between S-BP and SmartMeter is OK;
2. Make sure load power is higher than 150W;
   • a. Battery will does not discharge continuously unless load power is higher than 150W;
   • b. If battery still not discharge when Meter power is higher than 150W, then please check SmartMeter & CT connection and direction;
3. Make sure SOC is higher than I-DOD. Or if battery discharged to below I-DOD, than battery will only discharge again when SOC charged to [20% + (I-DOD)]/ 2 and SOC > 105% – DOD (if battery discharge is required immediately, battery should be restarted);
4. Check on App if it is charge time,, during charge time, battery will not discharge (battery will charge in priority during coincident time of charge/ discharge).

Battery does not charge:
Possible reason:

1. Smart Meter communication fails or CT connected in a wrong direction, which gives S-BP wrong data.
2. Battery is not in the condition for charging, such as high SOC, battery communication fail for lithium batteries etc.

Solution:

1. Make sure BMS communication is OK on SolarGo (for lithium batteries);
2. Check if CT is connected in the right position and in the right direction as stated in the user manual.

Questions & Answers (Q & A)

About the Wi-Fi Configuration

• Q: Why can’t I find the Solar-Wi-Fi* signal on mobile devices?

• A: Normally Solar-WiFi* signal can be found after inverter powered up.
  Please check if Wi-Fi module is connected well, and make sure inverter is powered up normally. Note: If Wi-Fi LED on inverter is single-blinking (0.5s on & off), then it means Wi-Fi module is not connected or not connected well.

• Q: Why can’t I connect to the Solar-Wi-Fi* signal on my phone?

• A: It can connect to only device at a time. So please make sure other devices are not already connected to the signal.

• Note: Please make sure the password of the Wi-Fi signal (12345678) is not wrong.

About Battery Operation

• Q: Why does the battery not discharge when the grid is not available but it discharges normally when the grid is available?
• A: On the APP, the off-grid output and backup function should be turned on to force the battery to discharge under off-grid mode.
• Q: Why is there no output on the backup side?
• A: For back-up supply, the Back-Up function on SolarGo App must be turned on. Under off-grid mode or grid power is disconnected, Off-Grid output function must be turned on as well.

Note: When turning on Off-Grid output, don’t restart inverter or battery, otherwise the function will switch off automatically.

• Q: Why does the battery switch always trip when it starts up (lithium battery)?
• A: For lithium battery like LG, normally the switch trips for following reasons:

1. BMS communication fails.
2. Battery SOC is too low, battery trips to protect itself.
3. An electrical short circuit occurred on battery connection side. Or other reasons please contact GoodWe for details.

• Q: Which battery should I use for S-BP?
• A: For S-BP inverters, it could connect lithium batteries, with nominal voltage 48V, max charge voltage 60V.
  Compatible lithium batteries please refer to S-BP QUICK INSTALLATION INSTRUCTIONS

About SolarGo Operation And Monitoring

• Q: Why can’t I save settings on the SolarGo App?
• A: This could be caused by losing the connection to Solar-Wi-Fi *.

1. Make sure you are connected to Solar-WiFi* (make sure no other devices connected) or router (if connected Solar-WiFi* to router) and on APP home page shows connection is stable.
2. Make sure S-BP is under wait mode (on App) before you change any settings on SolarGo App disconect grid/load, only leave battery connected and then restart S-BP till the work mode displays “wait” on the App.

• Q: Why are the data displayed on the homepage different from the param page, like charge/discharge, PV value, load value, or grid value?
• A: The data refresh frequency is different, so there will be data discrepancies between different pages on the APP as well as between these shown on the portal and APP.
• Q: On the App, why are the data displayed on the homepage and param page different, like charge/discharge, load or grid value?
• A: The data refresh frequency is different, so there will be a data inconformity between different pages on App as well as between that on the portal and App.
• Q: On the App, some columns show NA, like battery SOH, etc. why is that?
• A: NA means App does not receive data from inverter or server, normally it is due to communication problem, such as battery communication, and communication between inverter and the App.

About Smart Meter and Power Limit Function

• Q: Is power limit function possible for S-BP system?
• A: Please refer to 2.4.3 Smart Meter & CT Connection for details of this function on S-BP system.
• Q: Can I use other brand’s Meter to take over Smart Meter in S-BP system or change some settings on Smart Meter?
• A: No, because the communication protocol between inverter and Smart Meter is in-build in the Smart Meter, other brand’s Meter cannot communicate. Also any setting change could cause Smart Meter communication failure.
• Q: What is the max current allowed going through CT on Smart Meter?
• A: The max current for CT is 120A.

Other Questions

• Q: Is there a quick way to make the system work?
• A: The shortest way, please refer to S-BP QUICK INSTALLATION INSTRUCITONS.
• Q: What kind of load can I connect on Back-Up side?
• A: Please refer to user manual on page 11.
• Q: Will the warranty of the inverter still be valid if for some special conditions we cannot 100% follow the installation or operation instructions of the user manual?
• A: Normally we still provide technical support to problems caused from disobeying the instructions of the user manual, but we cannot guarantee a replacement or returns. So if there is any special condition when you cannot 100% follow the instrucions, please contact after-sales for suggestions.
