Hi all,

I wanted to know what is the lowest SOC you should run the battery? Mine is currently default set at 35%.

My setup in the NW UK: 4kw PV Southfacing - panels ~7 yrs old, newly installed sunsynk 3.6Kw inverter with 2 x 5.1KWh batteries.

My plan is to have 2 generic setups - summer/winter. Summer maximises battery load from PV and Winter uses off peak electricity to top up battery to utilise through the day.

I just need to know what parameters I can set the battery charges to maximise usable battery capacity, whilst still looking after the long term battery health.

Thanks in advance.

Simon
