The WHMU-1000 series steps up performance, delivering 1000W continuous power (2000W peak) alongside battery charging capabilities. Available in DC12V or DC24V input versions, it supplies modified sine wave AC power for 100-120VAC or 220-240VAC systems. The integrated multi-stage charger provides 15A (12V) or 10A (24V) charging current, accepting universal AC input voltages (90-135V / 190-260V). It features a 5V 1A USB port, reaches 90% maximum efficiency, and employs intelligent air cooling. Comprehensive protections are standard, guarding against voltage issues, overload, heat, shorts, and reverse polarity.
