Hi.
I have a Narada 48NPFC100 connected up to a 5kVA Voltronic inverter (Skyking) and have a bit of what another user wrote, buyers remorse.

First issue:
The inverter is connected to a raspberry PI and I read all the stats I require from the inverter, but the inverter has no idea what the battery is up to and reports very dodgy statistics on the battery current as I have read on this forum.

The battery is connected to the same raspberry PI using a RS485 TTL adapter and I figured out that the slave id of the battery is (38), but cannot read any of the registers from there.

A Narada technician was kind enough to check the battery for me, he opened a program named BMS on windows and it automatically picked up the battery and could read everything from SOC to number of cycles. Of course, I could not get a copy of the program, but it does mean there is a way to read the information from the battery.

Second issue:
Sometimes the battery just suddenly turns off all current (on full charge), I think it is trying to protect itself from fast discharge but my stats on the inverter does not show high discharge. The inverter has to quickly switch to a different source of energy and there is a noticeable power dip. I physically have to restart the battery to get it to work again but I think this is definitely bad for the inverter and for the appliances connected to the inverter.

Any help would be greatly appreciated.

For anyone else that may have the same issue as I had with the battery switching off, I finally figured out that my logic was incorrect, I worked out the Amperes using 230V/240V instead of using the batteries 48V so the Amperes I was pulling were too high and the battery switched off to protect itself. Adding a second battery should solve the issue I have been told by the suppliers of Narada batteries.
