Required load energy
4,800 Wh
Energy demanded by the connected load over the configured backup window.
Preliminary calculator
Battery calculator
Estimate nominal battery-bank capacity from load power, autonomy time, system voltage, efficiency, and depth-of-discharge limits.
Assumptions used by this preliminary calculator
- Load energy is converted to required nominal battery energy using inverter efficiency and maximum depth of discharge.
- The recommended Ah value is rounded up to a common battery-bank capacity step for quick planning.
- Final battery design still requires chemistry, discharge-rate, temperature, charging, and lifecycle review.
Minimum nominal energy
6,521.74 Wh
Nominal battery energy required after accounting for efficiency and usable depth of discharge.
Minimum nominal capacity
271.74 Ah
Calculated minimum battery-bank ampere-hour requirement.
Recommended battery bank
300 Ah
Rounded planning value based on common battery-bank capacity steps.
