Inverters - general information why an inverter is needed the utility grid supplies you with alternating current (ac) electricity. Ac is the standard form of electricity for anything that “plugs in” to the utility power. Direct current (dc) electricity flows in a single direction. Batteries provide ...

Page 5 loads that require “surge power” to start resistive types of loads (like incandescent lamps, toaster, coffee maker, electric range, iron etc) do not require extra power to start. Their starting power is the same as their running power. Some loads like induction motors and high inertia motor d...

Page 12 devices that may not operate on modified sine wave the output wave form of these inverters is a modified sine wave. See the diagram under “principle of operation” on page 11. In a sine wave, the voltage rises and falls smoothly with a smoothly changing phase angle and also changes its polari...

Sizing the inverter battery bank one of the most frequently asked question is, “how long will the batteries last?’. This question cannot be answered without knowing the size of the battery system and the load on the inverter. Usually this question is turned around to ask “how long do you want your l...
