EasySolar-II GX 48/3000/35 powering on and off

I have a EasySolar-II GX 48/3000/35 powering on and off , batteries are 4x rittar 12V200Ah/10HR


This have worked fine until recently when in battery operation it starts to turn on and off. Right now its winter and dark here so not really getting anything from solar panels. Connected to grid there's no problem. Its installed in a tiny house.

Its installed and configured by a previous owner.


Current settings


Battery voltage: 48v

Max charge current: 16A

Absorption voltage: 58,80v

Float voltage: 55,20v

Equalization voltage: 57,60v

Automatic equalisation: disabled

Temperature compensation: disabled

Low temp cut-off: 0c


Relaymode: battery voltage low

Minimum closed time: 1h

Battery low voltage relay: 53v

Clear battery low voltage 55v


Batter voltage today: min 51,96, Max 58,79


Is there any obvious faulty setting above?


Thankfull for advice

@Walrus

It is likely your battery internal resistance is high and the voltage is dropping under load.
