Off-Grid Common Components

The image and explanations below share what the major components are on a Commodore off-grid pre wired board

Inverter - The inverter charger has two functions, it converts 48v DC power from the batteries and Solar to 240v to power appliances.

MPPT Charge Controller - this brings in the Solar power from your Solar panels and converts that power to 48v which can be used either directly from the inverter with excess power charging the batteries.

Cerbo GX - this is the central brains unit for the whole off grid system connecting the inverter, MPPT batteries and generator to all work seamlessly together.

Cerbo Screen - this screen allows you to view how your system is working and also to access settings.

AC breaker box - this box is where the electrician wires circuits either to another switchboard or can run circuits directly to loads from here. This is where the breaker(s) for the generator are or can be added to later.

DC breaker box - this is where the DC breakers are held which are for the Solar panels.

Battery Isolator - this isolator is the protection between the batteries and the inverter.

Wifi Module - we often use these on a pre wired board which is AC coupled with a Solar inverter like a Fronius, not usually needed on other installs.

Generator Plug - this is a 15a plug that we put on most boards that you can plug any generator into to charge up the batteries. Larger pre wired boards often have provision in the means of a bigger breaker in the AC breaker box.

GPO’s - often there are either 10 amp and/or a 15 amp GPO (powerpoint) on the board
