@mzezman If I may hop in here as my issue seems related.... My system is taking ac from the grid at seemingly random times even though the AC charge times are all set to 00:00. the AC first settings are also all at 00:00. The sun is out and the panels are doing what they're supposed to.... I also set the AC charge to 'DISABLE', and even then it charged the battery from around 70% (I think) to 100% today - at around midday while the panels were generating beautifully. As a matter of interest I also set the AC charge end battery SOC to 90% (as suggested by my installer) - It chrged all the way to 100% if you have any insight I'd be very grateful Regards

I have been using exactly that method to charge the battery at night, and it performs as expected - It's the unexpected ones that I'm scratching my head about. Where I have not set the charge times to charge at all - ie they're at 00:00 start and 00:00 end. I can try as you suggested but I'm not sure how it's any different to what I was already doing? thanks anyway for taking the time to help

Hi @zsde Thanks ! - What outcome should I expect from the test ? a one minute charge at midnight - hopefully cancelling out any other charges?

Hi If anyone can help with this please? I have a Luxpower eco hybrid inverter - SNA5000 WPV, my battery is a CFE-5100S I'm aware of how to request a time based charge from the grid via the app and have used this successfully nightly. However, the system has been charging the battery via the grid seemingly randomly the last few days - until the battery hits 100%. Even though I have all the times set to 00:00 - ie no request for grid/ac charging, And even though the sun was still out (3/4pm, ) and the battery was at around 70% charge. I've mailed luxpowertec and they say: Battery BMS requested to force charge battery from AC, Please check with battery engineer to resolve this issue. here's the screen shot from luxpower and here's what the app showed at the time of random charging
