Victron makes some amazing inverters, my configuration runs the house from solar powered batteries when possible, then connects to the grid when necessary to maintain power continuity. If you are willing to utilize some grid for stability it can be pretty painless. It also accepts two AC inputs and can start a generator as an outage option.

I refuse to pay for victron at this time. I don't have the space for separate components, and thus I opted for the less expensive and more space conseving AIO unit.
They are definitely expensive. I like the UI, it’s pretty handy. I can connect to the MPPT controller via Bluetooth, check the BV and production profiles, know when to go clean the panels…in the long run on a primary source system, I think the cost is worth it for the configuration flexibility alone. I’m also building a second water wheel powered AC input, having the dual input prority programmable options is going to be key to eliminating the grid altogether, or using it only for system failure.
Yup. If you've got the space and want that kind of flexibility, Victron really is a top choice!
