Hi community,
I want to take some safety and be sure that my generator will never get feed-in from the PV inverter, so my flow is like this:
- if the grid has been lost and batteries go near 20%, I will start the generator (a small gasoline generator, without automation functions)
- then on CerboGX, change AcSource to Generator (there is no way to change using automation, over Modbus, unfortunately)
- the change of ac-source-type will trigger an automated workflow that will change a contactor to enable the generator and also change ac-in Amps to what the generator can make (24A) (Modbus /Ac/ActiveIn/CurrentLimit)
- Multiplus will soak as much energy from the generator as possible from AC-In + PV solar (Fronius) on ac-out
- while batteries are low, and still in bulk is It safe to run PV solar (Fronius) with the generator on ac-in? is it possible to get feed-in by multi into the generator?
- The batteries will reach some "end" goal which is 80%, my plan is to disable the PV inverter using `/PvInverter/Disable` Modbus, this will give me an opportunity to PowerAssist OR change the contactor that goes to a generator
As for now, my main concern is safety and not burning generators with feed-in, all other automation of how to get back to the grid could be automated later.
Thanks for the help!
