Disconnect BYD Battery from easysolar

Hi, i want to know if i have any risk of damaging anything if i disconnect (rotary switch 300Amps and shut down battery) the BYD battery from EasySolar when PV is connected at Night and during the week end. I don't want to leave the new installation "alone" for the moment.

i've see here many differents answers but no one really match my case...

I understand it can not dammage the MPPT but it can occure an overvoltage when i disconnect it, that's right ?


Thank you

make sure there's no current while you disconnect to minimise contact damage due to arcing from breaking a live circuit.

Ideally you should have the ability to precharge the easysolar before you reconnect, to minimise contact damage from capacitor inrush

Thank you for your answer, but what did you mean by Precharge?
