There are different types of off-grid systems which we will go into more detail later, but for now I will keep it simple. This description is for an AC coupled system, in a DC coupled system power is first sent to the battery bank, then sent to your appliances.

The battery bank. In an off-grid system there is no public electricity grid. Once solar power is used by the appliances in your property, any excess power will be sent to your battery bank. 

Once the battery bank is full it will stop receiving power from the solar system. 

When your solar system is not working (night time or cloudy days), your appliances will draw power from the batteries.

Backup Generator. For times of the year when the batteries are low on charge and the weather is very cloudy you will generally need a backup power source, such as a backup generator or gen-set. 

The size of the gen-set (measured in kVA) should to be adequate to supply your house and charge the batteries at the same time.
