Samlex DC-AC pure sine power inverters convert DC voltage provided by a 12, 24 or 48 volt battery into AC current, similar to the current provided through a household electrical outlet. Choose from Pure Sine Wave or Modified Sine Wave power inverters to provide reliable AC power from your RV, boat, automobile, solar system, or stand-alone battery. It is recommended that battery isolators be used when auxiliary batteries are being used with inverters.
