Solar and backup power in Johannesburg North — what we actually find
The limiting factor on many Johannesburg North installations is the original 1970s mains cable, which was never sized for the loads already added, let alone an inverter and battery system. We check the supply side before designing anything. Overhead service connections are also worth assessing, since storm damage there is common and change-over behaviour needs to be right when it happens.
Property stock in Johannesburg North
The established freehold suburbs of Johannesburg North sit on mature gardens with decades-old trees, and root intrusion into clay sewer lines is the single most common cause of the blockages we clear. Overhead municipal feeds are still common, so storm damage to a service connection presents exactly like an internal fault. Many homes still run the original 1970s mains cable, undersized for everything added since.
Mostly freehold with direct access. On larger stands we allow time to locate boundary stop-cocks and the point of entry before diagnosing.
Faults that cluster in Johannesburg North
- Root intrusion into original clay sewer lines under mature gardens
- Storm damage to overhead service connections mimicking an internal fault
- Original 1970s mains cable undersized for present-day loads
- Repeat blockages returning months after rodding because the pipe itself has failed
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 Johannesburg North 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
