Solar and backup power in Pretoria — what we actually find
Pretoria properties usually already run pool pumps, borehole pumps and irrigation on circuits added years after the original board, and those additions are the usual source of earth leakage. They have to be sorted before they sit behind an inverter, because a nuisance trip that was an annoyance on municipal supply becomes an outage on backup. We isolate and test each one during design.
Property stock in Pretoria
Pretoria's older suburbs run higher municipal pressure than most of Johannesburg, and without a working pressure-reducing valve that pressure destroys geyser elements and mixer cartridges early. Summer storms overwhelm older gully traps that were never sized for the runoff. Electrically, pool pumps, borehole pumps and irrigation were usually added years after the original board and are where earth leakage tends to start.
Direct access on most freehold properties. Where a pressure-reducing valve or added pump circuit is involved, we test at the meter and the board rather than working from assumptions.
Faults that cluster in Pretoria
- High municipal pressure destroying geyser elements and mixer cartridges early
- Missing or failed pressure-reducing valves behind repeat leaks
- Older gully traps overwhelmed by summer storm runoff
- Pool, borehole and irrigation circuits added after the original board causing earth leakage
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 Pretoria 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
