"It wasn't raining when Noah built the ark."-- Howard Ruff
Good points.I planned a grid-tie system, then rejected it due to the complexity of a hybrid off grid/grid tie system and the low rates for buyback. Another thing I'm looking at is a whole house LP generator as a backup to solar to charge the batteries. This would keep me independent in grid down for the duration of my propane stores. Also in the cards is a PTO generator to supplement power with diesel fuel. Like a lot of my systems, Plan A, Plan B, Plan C... During normal use, utilizing a whole house generator to supplement solar could get me off the grid, but, and this is a weird but, I have a street lamp that lights up the whole cul de sac. I pay a flat fee for it, and it doesn't go through my meter. It sounds like a weird priority, but it burned out once, and being the middle of nowhere, it was so super dark it was a little off putting. I'd like to maintain enough of an electric service to keep that running during grid up. In SHTF, the darkness could be an asset.
What does your solar guy say about integrating a whole house generator into the house system?
If He used a Connex XW6848 inverter it has a generator start module accessory that will start & run the generator, charge the solar battery and turn it off again all unattended.
