Estimate your solar battery backup time in hours. Supports 5kWh, 10kWh Lithium (LFP) modules and Tubular batteries with Depth of Discharge (DoD) analysis.
Battery Bank Configuration
Avoid discharging Lead-Acid batteries below 50% as it significantly reduces their lifespan. Lithium batteries are much more resilient.

At a constant load of 1000W, your battery bank is discharging at 20.0% of its total capacity per hour.
We've accounted for a 10% inverter overhead in our calculations to ensure you get a realistic estimate of your backup time.
Understanding your battery backup is essential for surviving load-shedding and optimizing your off-grid solar system.
To calculate backup time, you need to know three things:
Don't get confused by panel wattages. Learn how to accurately calculate your total solar kW capacity, daily unit generation, and roof space requirements.
Everything you need to know about energy storage in 2026. From Lithium LFP modules to backup time calculations and NEPRA regulations.
