The request
“A home with 6 kW of solar and a Tesla Powerwall (5 kW, 13.5 kWh) on a hybrid inverter. A backup gateway switches between the grid, through the smart meter, and the inverter, then a 230 V consumer unit with a 63 A RCD feeds lights, sockets, kitchen and a 7.4 kW EV charger, with cable sizes.”
Then tryMark which circuits stay on in a power cutAdd a solar diverter for the water heater
What is in this drawing
Read the decisions behind it.
01
Use of hybrid inverter to manage solar and battery DC inputs
02
Backup Gateway as automatic transfer switch between grid and inverter AC output
03
Main consumer unit with RCD and individual circuit breakers for load groups
When planning or documenting a grid-tied residential photovoltaic installation with battery storage and islanding capability for critical load backup.
