Hi @Aphere and @Lyndon_S, Thank you for your interest in the EP760. Like all our other models, the EP760 uses lithium iron phosphate (LiFePO4) batteries.
We regret to inform you that the SOC charging limit setting you mentioned cannot be used in off-grid scenarios. In off-grid operation, the system will utilize all available battery capacity.
You can rest assured that charging the EP760 to full capacity will not affect the battery’s service life. Please feel free to charge it completely.
I’m curious? I’ve had my EP760 operational for just over a month and I have my SoC setting set to 30-95% as I want to maximise the usable capacity each day. Once it reaches 95% it never shows at SoC level above that (despite what was said eariler that it will continue to charge on solar alone after the SoC limit is reached).
I did briefly change it one night when my wife was smashing it with power consumption and that was the only night that it drew power from the Grid at SoC of 50% (other than the trickle amount it draws each day of 0.15kWH-0.3kWHr/day, that it seems to need to remain co-ordinated with the grid) .
With the battery maintenence setting, is it recommended/encouraged to utilise this feature when you know that your going to have good solar day(s) or do you also need high demand days at the same time to bring the SoC down before recharging kicks in?
