Off-Grid systems are ideal for remote buildings where there is no direct connection to Eskom. It allows the user to supply essential appliances with power.
These systems have no connection to mains electricity and the power generated comes purely from the solar panels. A generator can however be connected to provide power if the system does not provide sufficient power.
Any extra power generated by the solar panels will be stored in the batteries to be used at night. If the batteries are fully charged any additional power that is generated by die solar panels will be lost.
