The consumer unit / breaker panel that splits the inverter’s AC output into protected circuits for your sockets and appliances.
The inverter’s AC output has to be split into protected circuits for your sockets and appliances — with the right breakers and an RCD/GFCI to protect people.
It sits on the inverter’s AC output (or shore inlet), distributing mains power to your AC circuits behind breakers and a residual-current device.
Design your van, boat, cabin or RV system in Wattonomy and it adds an AC panel with a residual-current device on the inverter output when your design includes AC loads — from the appliances you actually run, sized to the recognized standard for your region. You see it on the wiring diagram, in the sized parts list, and in a plain-English build pack that explains the reasoning behind every choice. No account, no email — about a minute to a complete, validated design.
If you run mains appliances from an inverter or shore power, yes — the AC side needs breakers and an RCD/GFCI to be safe and compliant.
It cuts power fast if current leaks to earth — for example through a person. It is required on inverter and shore AC circuits.
