I'm not privy to the specs, but from what I understand the off-grid allowance is less than the grid-interconnected allowance. I'm guessing here, but I assume they would limit the PV inverter output to the AC power rating of the internal inverter which I believe is 5kW. That way the PV output could never be higher than what the Powerwall could handle.
