Solar Panels Job - Cyrildene, GP, 2198

We have 4 off-grid lights at a block of flats, which require troubleshooting and repair. Each has a solar panel and MPPT to charge a deep cycle battery, which powers the lights at night (switched by a day/night sensor). We also need relays installed at each light which keeps the lights off when municipal power (and normal timer-switched lights) are on so that the batteries are not drained at these times.
