Inverter and UPS wiring so backup powers the right circuits
Separate backup circuits, changeover and safe battery placement so lights, fans and Wi-Fi stay on during power cuts.
An inverter is only as useful as its wiring. Many homes have backup connected to random points, or to heavy loads that drain batteries in minutes.
RennovEN wires a dedicated backup circuit to the lights, fans, routers and chargers you actually need, with safe changeover and ventilated battery placement.
Signs you need this
- Backup drains quickly during cuts
- Wrong rooms stay on during power cuts
- Extension cords running from the inverter
- Battery placed in a closed cupboard

Why it happens
