Solar and backup power in Randburg — what we actually find
In Randburg the sizing conversation matters more than the panels. Homes converted into offices and back rooms have loads well beyond what the original board assumed, so we calculate actual demand before specifying anything. Sub-boards feeding cottages and outbuildings without their own earth leakage have to be corrected as part of the work, since the installation is certified as a whole.
Property stock in Randburg
Randburg's older freehold homes around Ferndale and Blairgowrie still have galvanised supply pipe in the walls, and once it starts weeping the pressure drop shows at the furthest tap first. Complexes here often share a single bulk meter, which makes one unit's internal leak everyone's problem. A high proportion of homes have been converted into offices or back rooms, each conversion adding load to a board sized for a family house.
Freehold access is direct. On bulk-metered complexes we coordinate with the managing agent, because isolating to test a single unit affects the others.

How solar and backup power works
The expensive mistake in solar and backup is sizing, not equipment. Undersize it and you are disappointed every outage; oversize it and you have paid for capacity that never gets used. Essential-loads wiring is what makes the numbers work — splitting the board so the inverter carries lights, plugs, fridge, Wi-Fi and security while the geyser and stove stay on the grid side. Without that split you are effectively sizing the whole system around the geyser.
- Load surveys based on twelve months of actual consumption rather than estimates
- Hybrid inverter and LiFePO4 battery installations sized to real essential loads
- Solar PV with shading analysis and string layout matched to roof orientation
- Essential-loads board splits and correct isolation
- Electrical COC on completion, and City Power approval where the system is grid-tied
Our process on a Randburg call-out
- 1Survey the site — roof orientation, shading, roof space and board condition
- 2Review twelve months of bills to size against real consumption
- 3Agree the essential-loads circuit list before anything is ordered
- 4Install, commission and demonstrate the system under an actual outage
- 5Issue the Electrical COC and handle grid-tied approval where it applies
