AIMS 4000 Watt Pure Sine Inverter Charger 48Vdc/240Vac Input & 120/240Vac The AIMS Power low frequency 4000 Watt 48-volt, split phase Vac power inverter charger is not your average every-day power inverter. This is a top-of-the-line power inverter, built for the purpose of running your whole house (smaller home), business office or large RV. This inverter charger is perfect for your off grid system or for use as an emergency backup supply. Built with a 48 volt DC input, this inverter performs with very little power loss. Users receive a notable increase in efficiency in large systems when compared to using inverters that accept 12 or 24 volts. The 4000 watt inverter charger can utilize 240V grid power to charge the batteries and send the power out to your application using the built-in 40 amp charger. If the grid power is lost, this inverter is equipped with a seamless automatic transition transfer switch, becoming a true UPS (Uninterruptable Power Supply) when you need it in emergency situations and natural disasters (battery required). This inverter charger also comes with an Auto Generator Start mode that can tell a generator to start up and begin providing charge to the batteries (through a separate charger on 240V gensets).
