Im looking at getting a 25kw inverter with 48kwh battery.

What i am confused about is the installer says the full 63A 3 phase can be pulled from grid to backup (house) and there is only a limit of 25kw when pulling from the battery.

However reading the specs of the gateway it says 30kw limit on backup output and 30kw limit on grid connection.

I want to be able to run a 22kw ev charger and full house load (at times more than 12kw) from the grid during the free eletricity period.

Can I use the standard TP gateway or do I need the C60 unit?
