low battery flashes red on multiplus but battery voltage is 53v
I started changing my multiplus from off grid situation to on-grid. I configured the country code and added the ess assistant including pv on ac out.
The ac in is not connected yet.
After uploading the settings the low battery flashes red even that the battery voltage is 53v.
The multiplus also doesn't start charging with the power of the PV on ac out 1 (clould be the power production is too low at this point : 40w but no loads so was expecting some minimum charging)
