Zero-downtime power for hospitals — Solar + Battery + Generator resilience
Hospitals cannot lose power. LEONICS delivers grid-interactive PV + battery + generator so critical loads — ICU, operating theatres, imaging, and the cold chain — ride through grid failures seamlessly, with solar cutting the round-the-clock bill. Proven at Dhulikhel Hospital, Nepal.
Design figures for a system sized to this use case. What a given site actually gets depends on its load shape, the PV and battery sizing and its tariff — the worked examples below show the inputs.
The Challenge
A hospital cannot lose power — an outage threatens operating theatres, ICUs, and the vaccine/blood cold chain, yet diesel-only backup is costly and slow to switch over.
- Zero downtime — Operating rooms, ICU, and life-support cannot tolerate an outage — even a few seconds is dangerous.
- Unreliable grid — In many regions the grid fails often, so the hospital must be able to rely on itself.
- Diesel-only isn’t enough — Gensets alone have a transfer delay, high fuel cost, and emissions.
- Cold-chain at risk — Vaccines, medicines, and blood need uninterrupted refrigeration — even a short outage causes loss.
- Costly critical load — Running critical loads on diesel over the long term is expensive.
Solar and battery join on the DC side; grid and genset tap the AC bus. The critical bus is fed through one grid-interactive inverter.
