BATTERIES

To achieve 50% cycling you should calculate your Amp-hour consumption between charging cycles and use a battery bank with twice that capacity.

To calculate Amp-hour consumption first look at the rating plate on your AC appli- ance or tools. Each appliance or tool will be rated in either AC Amps or AC watts or AC VA (Volts-Amps) apparent power. Use one of the following formulas to calculate the DC Amp-hour draw for a 12 Volt system:

(AC Amps x 10) x 1.1 x hours of operation = DC Amp-hours

(AC watts/12) x 1.1 x hours of operation = DC Amp-hours

(AC VA/12) x 1.1 x hours of operation = DC Amp-hours

In all formulas, 1.1 is the factor for inverter efficiency.

Calculate the above for every AC appliance or tool you intend to use on your inverter. This will give you the total number of Amp-hours used between recharges. Size your battery bank using this number as a guideline. A good rule to follow is to size the battery bank about 2 times larger than your total Amp-hour load requirement. Plan on recharging when 50% discharged.

Many electric motors have momentary starting requirements well above their op- erational rating. Start up watts are listed where appropriate. Individual styles and brands of appliances may vary.
