Whenyouoperatetheinverterforlongperiodsoftimecombinedwithahighcontinuousloaddemand,theresult

tousetopoweryourinverter.

To calculate the approximate

 power drain on your battery you will want to estimate the reserve power

("amp/hour")ofthebatteryandtheampstheinverterwillrequire,tomeetthecontinuousloaddemandofthe

2. Toestimatethemaximumbatterypowertheinverterwillrequiretorunapieceofequipmentorappliance,
