Independent energy/ CALCULATOR

Generator-assisted battery recharge plan

Estimate recharge time, generator-side demand and fuel for a stated battery deficit.

Battery energy deficitkWhEnergy that must actually be added to the battery between the chosen states of charge.

Average battery-side charge powerkWUse sustained power accepted by the battery, after any taper or control limits.

AC-to-battery efficiency%Combined conversion efficiency from generator AC output to stored battery energy.

Concurrent household loadkWAverage load supplied by the generator while the battery charges.

Fuel use at planned loadL/hUse manufacturer data or measurement near the calculated combined load.
