Hello. I keep seeing ‘write failure’ whenever I try and schedule a charge on my battery (see second attachment). I also have the energy stats app. When I try it from there it shows a ‘44098 write failure’ (see first attachment).

My setup is:

Fox ESS KH 9kW 1ph Hybrid Inverter inverter

3x Fox ESS EQ4800-M 4.66kWh Li-ion battery

Any help greatly appreciated!

You have mode scheduler enabled, you can’t run the older charge periods at the same time as scheduler - if you disable the scheduler, charge periods will work again.

Alternatively if you are using scheduler, set a force charge schedule instead of using charge periods.

Ah thank you so much Dave! I’m *still* waiting for DNO approval, so just making sure I’m all set when it does actually come through.
