The power required to run an inverter is approximately 8-10% more than the power load of the appliances being run. This is due to the efficiency of the inverter. These days, quality inverters are between 90-92% efficient. An easy formula to use to WORK out how much DC Amps you will use from your battery is, simply divide the AC wattage of your appliance by 12 (or 24 if a 24v SYSTEM) and times this number by 1.1 to get a very close ESTIMATE of the DC draw.

Inverters will draw power from your batteries when not in use, and the unit is turned on. This can vary from around .02 amps right up to 2 amps depending on the unit and design of their standby systems if you leave your inverter turned on with no load attached, the average draw from your batteries will be 1 amp per hour; 24 amps per day; or 168 amps over a week. The simplest solution to this is to just turn the inverter off when not required as the battery drain then becomes zero. Many of our inverters feature standard or optional remote on/off controls.
