Inverters are solid state devices which change DC to 120VAC electricity. They are sufficiently rugged and reliable to make them practical for use on utility vehicles for operating thumpers, tools, lights and induction motor loads. The SCR type rather than the transistor type inverter is generally required for inductive and reactive loads.
Static inverters operate from battery input. They provide power without running an engine, but are limited by battery capacity so work best in intermittent load applications.
Dynamic inverters operate from alternator input and will handle continuous loads to 7200 watts with truck engine running.
