Electrical Wiring Connection

2.4.1 Battery Wiring Connection

• For lithium battery (pack) the capacity should be 50Ah or larger. lead-acid batteries are not allowed for use with GoodWe hybrid inverters without GoodWe’s authority. Battery cable requirements are shown below.

• Please be careful against any electric shock or chemical hazard
• Make sure there is an external DC breaker (≥125A) connected for batteries without a build-in DC breaker

Battery wiring connection steps as below:
**** Make sure the battery switch is off and battery nominal voltage meets S-BP specification before connecting the battery to the inverter and make sure the inverter is totally isolated from PV and AC power.[4]

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

1.  Please use accessories from the GoodWe box
2. The battery power cable should be 25-35mm

Step 2
Make battery terminals:

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

Step 3
Connect battery terminal onto inverter.
Note: Please make sure polarity (+/-) of battery are not reversed

• For the compatible lithium batteries (LG / PYLON / BYD / GCL / DYNESS / ALPHA) connection, please refer to battery connection part in S-BP QUICK INSTALLATION INSTRUCTIONS.

Battery Protection Description
The 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, the battery is protected from over-discharge by DOD and discharge voltage, under the 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 a load of the 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 behavior is different between battery manufacturers’ products, however, if the SOC of the battery reaches a certain level the inverter will boost the SOC back up. This protection mechanism safeguards the battery to fall to

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

• The on-grid wiring connection process is as below:
  **** Make sure the inverter is totally isolated from any DC or AC power before connecting AC cable.[5]

Step 1
Prepare the terminals and AC cables according to the right table.

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

Step 2

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

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

Step 4

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

2. Lock the cover and screw the cap on.

Declaration for backup function
The below statement lays out the 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 backup 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 backup 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 backup 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 the battery itself, battery current might be limited by some factors including but not limited to the temperature, weather, etc.

Declaration for backup loads
GoodWe S-BP inverter is able to supply a continuous 5000VA output(max 5500VA within 10s) on the Back-Up side. And the inverter will shut down when it is full loading with high ambient temperature if the 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 settings 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 convenient maintenance, an SP3T switch could be installed on the Back-Up and On-Grid sides. Then it is adjustable to support load by Back-Up or by grid or left alone.

Possible 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 a 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 the battery will only discharge if load power is higher than 150W.
4. Smart Meter communication fails or CT is connected in the 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 the 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 is discharged to below I-DOD, then 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, the battery will not discharge (battery will charge in priority during a coincident time of charge/ discharge).

Battery does not charge:
Possible reason:

1. Smart Meter communication fails or CT is connected in the wrong direction, which gives S-BP wrong data.
2. The 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 PV Master (for lithium batteries);
2. Check if CT is connected in the right position and in the right direction as stated in the user manual page 13;

Question & Answers (Q&A)
About Wi-Fi configuration
Q: Why can’t I find the Solar-WiFi signal on a smartphone?
A: Normally Solar-WiFi signal can be found after the inverter is powered up.
Please check if the Wi-Fi module is connected well, and make sure inverter is powered up normally.
Note: If Wi-Fi LED on the 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 find the Solar-WiFi* signal on smart 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 grid is not available, while it discharge normally when grid is available?
A: On App, off-grid output and back-up function should be turned on to make battery discharge under off-grid mode.
Q: Why is there output on the Back-Up side?
A: For backup supply, the Back-Up function on PV Master 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 the inverter or battery, otherwise the function will switch off automatically.
Q: Why battery switch always trip when starts it up (Lithium battery)?
A: For lithium batteries like LG, normally the switch trips for the following reasons:

1. BMS communication fails.
2. Battery SOC is too low, battery trips to protect itself.
3. An electrical short circuit occurred on the 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 PV Master operation and monitoring
Q: Why can’t I save settings on PV Master APP
A: This could be caused by losing connection to Solar-WiFi*.

1. Make sure you are connected to Solar-WiFi (make sure no other devices are connected) or router (if connected Solar-WiFi to router) and on APP home page shows the connection is stable.
2.  Make sure S-BP is under wait mode (on App) before you change any settings on PV Master App disconnect grid/load, only leave the battery connected and then restart S-BP till the work mode displays “wait” on the 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 in conformity 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 problems, such as battery communication, and communication between the inverter and the App. (For lead-acid battery, NA is normal)
About Smart Meter and Power Limit Function
Q: Is power limit function possible for S-BP system?
A: Please refer to page 11 for details of this function on S-BP system.
Q: Can I use other brand’s Meter to take over Smart Meter in the 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 brands’ 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 INSTRUCTIONS
