Q: Why battery switch always trip when it starts up?
A: The switch of lithium battery normally trips because of following reasons:
1. BMS communication fails.
2. Battery SOC is too low, battery trips to protect itself.
3. An electrical short-cut happened on battery connection side. Or for other reasons please
contact after-sales.
Q: Which battery should I use for A-ES?
A: For A-ES series inverter, it could connect lithium batteries which have compatibility with A-ES
series inverter with nominal voltage from 80V to 495V. For compatible lithium batteries please
refer to battery list in PV Master App.
About PV Master Operation And Monitoring
Q: Why can't I save settings on PV Master App?
A: It could be caused by losing connection to Solar-WiFi *.
1. Make sure you have already connected Solar-WiFi* (make sure no other devices connected) or
drouter (if connected Solar-WiFi* to router). App's homepage shows connection well.
2. Make sure you restart inverter 10mins after you change some settings because inverter
will save dsettings every 10 mins under normal mode. We recommend to change setting
parameters when dinverter is in wait mode.
Q: Why are the data displayed on the homepage dierent from the param page, like
charge/discharge, load value 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 these on portal and App.
Q: Some columns show NA, like battery SOH, etc. Why does that happen?
A: NA means App does not receive data from inverter or server because of communication
problem, such as battery communication, and communication between inverter and the App.
About Smart Meter And Power Limit Function
Q: How to activate anti-reverse function?
A: For A-ES system, the function could be realized by turning on anti-reverse function on App.
Note: Even if this function is turned on, there might still be a deviation of a max of 100W
exporting to grid.
Q: Why is there still power exporting to grid after I set power limit as 0W?
A: Export limit could be 0W theoretically, but there will be a deviation of around 50-100W for
A-ES system.
Q: Can I use other brand CT to take over in A-ES system?
A: No, because the CT ratio and Meter are well matched, the accuracy and data accuracy cannot
be guaranteed by replacing with other CT
Q: What is the maximum current allowed to go through CT on Smart Meter?
A: The max current for CT is 200A.
