Note: When turning on O-Grid output, don't restart inverter or battery, otherwise the function will
switch o 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 PV Master Operation And Monitoring
Q: Why can't I save settings on the PV Master 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 PV Master
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 dierent from the param page, like charge/
discharge, PV value, load value, or grid value?
A: The data refresh frequency is dierent, so there will be data discrepancies between dierent
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 dierent, like
charge/discharge, load or grid value?
A: The data refresh frequency is dierent, so there will be a data inconformity between dierent
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.
