December 8, 20241 yr I asked Solar Assistant support if there is a chance that they would add some configuration option for the Growatt SPF 5000 ES. But maybe the task can be achieved via the automation options as well? I would very much like to have control over the AC output. So either it would be helpful to adjust the time when AC output starts and stops (Option 50, please see attachment - at least adjustable via mqtt) or a switch to manually switch on/off AC output (guess that would be difficult using MODBUS on the Growatt SPF 5000 ES). Reason is, that the Growatt inverters use a lot of power even in standby as long as the inverter circuit for AC output is active. And it depends on battery state and/or time (even daylight savings time) when AC output should be active to avoid burning energy while solar power is not available. For the time controlled adjustments there would also be need to set the correct current date/time on the inverter. (I also experienced that the internal clock is off quiet quick) Are there already any options in Solar Assistant that might help? Or does anybody have clues about managing the inverter? Thanks in advance! Edited December 8, 20241 yr by woehrl
