Hi Folks im new to all this but I would like some advice
I have 50kw of batteries installed with my solar . at nigth if I transfer it to the grid they wil only ever charge to approx 80%.
how can I get them to charge up to say 95.00%

Batteries only charging to approx 80 %
Hi @Alan3737
Do you mine sharing your settings. Others on the forum might be able to narrow down your issue then.
I assume you're charging up over night using ESS scheduled charging. First place to check is if you've set the SoC to 95% in there. (Settings -> ESS -> Scheduled charge levels).
If you have the next thing i'd check is voltage/SoC calibration. It may be that your battery is reaching absorption voltage at 80%. If that's the case then either absorption voltage is set too low or the SoC is not correctly calibrated/not correct..
What is monitoring SoC within your system, is it coming from the battery BMS or do you have a smart shunt or equivalent monitor?
Thank you very much for the quick reply . I dont have ess as my system is different than my old one. I upgraded to get completely off grid.
I have now 2 inverters (One as a slave)Solar.jpg
