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
appliance.
1. Whencalculatingtheamp/hourofthebattery,findits“reserveminutes"rating.Thisistypicallyis

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