Max settings for On Grid cut off is 90%. This is always been… if you want to keep it at 100% 24/7 set the ac charge time to 00:00-23:59.
When the battery is charging it will stay at 56-57 but once the battery starts to discharge the voltage will drop around 53-54v. Battery at high voltage will...
are you using closed communication between the inverter and battery? If yes change your batt charge control to SOC instead of VOLT. If not set END 1volt lower than you battery spec charge voltage and for START set 2 volts lower than the END voltage..
Since you’ll be using the app to activate...
We do that recommended updating the inverter if everything are working but in this case if your build firmware is less than 1010, and you want ac couple with frequency shifting, you must update to the latest firmware available.
If you don’t mine DM your Inverter SN or Dongle Sn?
EG4 latest firmware is 1312 and lcd is v13..
Like i said the ac couple setting about Start and End Soc is only take place when the grid is down or in offgrid application. This will protect the battery from overcharging. It will shut down the ac couple when it reach the END SOC, the ac couple...
Make sure you have the latest inverter firmware and lcd update. 18kpv and Lux 12k operate the same way…
If the inverter is connected to the grid the export to grid must be enable and 0.1kw is minimum to make ac couple to work this will turn on the generator input relay on to power your ac...
ac couple must be connected to the generator input. and use ac couple setting under charge settings. Ac couple start (95%) and end (100%) must at least 5% gap difference. if you don't like to discharge your battery, use charge first (pv) settings.
