So helco plugs into the charger/inverter via a battery monitoring relay (or a simple switch), the dc side connects to your batteries, which are also connected to your solar array, and the AC side can supply a circuit or a small breaker box in your house. A separate breaker box could supply the helco only side.
Optimal battery size for a 4000w array would be 2 or 3 strings of 8 x 6v golf cart batteries. $1600-$2400 in batteries + say $300 more in cables.
So for as little as $2250 or as much as $4100 + relay/breakers you could be up and running and saving money. Not bad at all. I wonder why more people don't do this?
I like that option for those who fear being totally off the grid, but much prefer a quiet generator to do the charging. Studies have show the more control you have over your environment and life the less stress you have. I think the trick with solar is to have more panels than batteries to ensure they are topped off regularly.
