The reliability the residential sector demands
For homes, the realistic availability target is around 99.9% for common-area and unit loads. Silent operation and seamless changeover matter most — lifts, water pressurisation, common lighting, security and fire systems are the loads residents depend on, with estate-wide distribution for multi-block developments.
The loads that define homes — Lighting, Refrigeration, Water heater, Security, Home office — set the sizing and the priority of what must stay live during an outage. We base the design on a measured load profile so the system carries the worst real case (the heaviest motor start while everything else runs), not a brochure average.
The recurring challenges here — Family comfort, Noise sensitivity, Fuel storage, Automatic operation — are exactly what the engineering has to defeat: correct sizing, clean power, a fast and reliable changeover, the right protection, and an SLA that keeps the system ready. We solve them as a system (generator, UPS, solar and switchgear designed to cooperate), document it, and maintain it across every site under one contract.
