The 6000 Watt low frequency Inverter Charger has the power to get the job done. With a 20 second surge capacity of 18,000 watts (18kw) at a 220 volt split phase, the inverter is ideal for use with motors, pumps and compressors which generally require 3-7 times running power for startup. This split phase inverter is capable of producing 110/220V ac. It will work virtually anywhere in the world, with the ability to auto detect 50 or 60 Hz. Also, the built-in charger allows for you to use your existing grid power to maintain a charge on your batteries. It also includes an Auto-Gen start that will tell your Auto-Start Compatible generator to turn on and provide power for the 24 volt battery charger.
