This customer relocated from Gauteng and permanently moved into their holiday home in Port Alfred. As part of a total revamp, they decided to equip their home with a PV system to give them energy security in the event of load shedding.

The essential loads have the benefit of battery backup should a utility outage occur for whatever reason.
