Wholesale solar is overpriced.
1. Look at your electric usage (last 12 months of bills)
2. Check with your electric company on what happens if you sell them power
3. What are the building and electrical permit requirements in your area
4. What are the electric company regulations for grid connection
All solar inverters are setup to disconnect the grid loses power. It is not BS. Most of the grid-tied inverters are simply money saving systems and they must disconnect. And you do not want to put power down the lines when the grid is down. Yes, you can kill linemen.
Battery based systems are not difficult to build, but you need decide your purpose. If it is backup power, then there are solutions that direction. If you want to "net meter" yourself with batteries, there are choices that direction.
Battery based systems work better if you use DC coupling to the batteries.
We build hybrid solar energy systems. Battery based solar energy systems with integral backup generators.
