The inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. Once the pure sine inverter is turned on, it starts to invert the DC energy to AC regardless if a load is applied or not (I'll talk about this parasitic draw later). Now, if you wonder what kind of battery you should use for your sine wave inverters, you must first. . Pairing a right size capacity battery for an inverter can be a bit confusing for most the beginners So I have made it easy for you, use the calculator below to calculate the battery size for 200 watt, 300 watt, 500 watt, 1000 watt, 2000 watt, 3000 watt, 5000-watt inverter Failed to calculate field. .
