Utilize you vehicle's battery to efficiently power work site power tools, pumps, as well as your laptop computer. Continuously supplies 1250W of 120VAC power to (2) AC outlets from any 12VDC battery source. Frequency control locks AC output at 60Hz for operating stability of motor loads and other inductive loads with high current startup requirements. Note: To protect against high current draw that may occur during inverter failure, a fuse link rated at 200A should be positioned no more than 18" from the PV1250FC's battery in the positive line.
