I'm a newbie here, learning.
I just purchased a GroWatt SPF3000 24v unit with a 5kWh LifePO4 battery bank (coming). My starting point will be to add a smaller 4 panel solar array, but mostly use AC grid power (one way) to top up the batteries. The climate here has painfully low solar hours for 2 months a year, so the grid supply is necessary.
Grounding is where I am getting confused. Is the AC input in with its included ground wire, grounding the entire system, or do I need to deal with that separately? It seems to me that if my AC input was a generator, then I would require an independent grounding.
I'm sure someone has written about this specific setup somewhere, but can be hard to find since most write ups talk about fully off grid without a backup AC input.
