I have a Multi2 inverter, with a 250/100 VE.CAN MPPT and a Cerbo GX.
I would like to switch a relay based on the current PV generation (Watts or Current will work, but not Voltage as this does not relate to available power very well).
Idea would be: [If (PVGen > 1000W for > 5 min) then Relay on for 5 hours.]
This relay will then switch my pool pump on. This would ensure that the pool pump will only run if the sun is out - I do not want it running while it's overcast or raining.
I would prefer not having to rely on SoC as I want the pump to switch on before the batteries are charged up. I cannot find a way to do this - please point me in the right direction?
