Independent energy/ CALCULATOR
Battery autonomy after load shedding
Compare battery runtime before and after reducing the daily critical-load budget.
Use the rated energy capacity of the battery bank.
Respect manufacturer limits and the reserve in your operating plan.
Combined discharge, wiring and inverter efficiency for this estimate.
Use a measured daily total where possible.
Enter the load budget after switching off or rescheduling nonessential uses.
Energy available to loads
10.80 kWh
Autonomy at current load
1.80 days
Autonomy at reduced load
2.70 days
Autonomy gained
21.60 h
Interpretation:The reduced load adds about 21.6 hours of battery autonomy in this energy-only estimate.
Energy-only comparison with constant daily loads. Solar or generator charging, inverter power and surge limits, standby consumption, battery ageing, temperature and protection cutoffs are excluded. If the reduced budget is higher, autonomy gained will be negative.
