There's a reason why home battery storage systems needs to be connected to the breaker panel. You route power through it. When the batteries aren't needed then it's just a dumb relay for grid power. When you're drawing power from batteries it disconnects the grid.

Only a few industries ever draw power both from grid and local power sources at once (during peak load) and they route all the power sources through a power distribution system which prevents backfeeding.
