Multiplus II Detected Battery Capacity is incorrect

Q&A and troubleshooting DESS

Hi everyone,

I have noticed after enabling Dynamic ESS that the available/installed battery capacity showing on the Multiplus is incorrect. I have checked my ESS settings and made sure everything is correct there (200AH) but it still shows as 240AH installed/available.

Where does this reading come from? The BMS or is it calculated based on current/voltage etc.?

I have 2 x BSL 5.1kwh (100AH) batteries
MPPT 150/100

Appreciate the inputs!

Regards.

The battery reports it to the GX of that is where you are seeing it. So that is where the information comes from. DESS cannot affect that is is sent on CAN
The ESS assistant is something only you can define but does not affect the GX value
