Clear answer
Clear answer, explained.
For example, a 200 kWh battery powering 50 kW of essential loads provides roughly four hours of backup. Businesses often prioritise critical systems only—such as lighting, IT, refrigeration, or security—to extend runtime. Larger batteries or solar recharging during daylight can further increase backup duration.
Key points
What this means in practice.
- Typical backup duration: 2–6 hours
- Runtime = battery capacity (kWh) ÷ load (kW) Critical load panels extend outage coverage
- Larger batteries provide longer backup
- Solar can recharge batteries during daytime outages
- Designed for resilience, not full-building operation
When this applies
Best-fit environments.
- Businesses needing outage protection
- Retail, healthcare, food storage, and office facilities
- Solar-plus-storage or microgrid systems
- Sites in areas with weather-related outages or grid instability
