The AIMS 4000-Watt， 48-Volt DC to 120-Volt/240-Volt AC pure sine wave inverter charger with built-in transfer switch and battery charger is your solution for backup or off grid power solutions. This inverter is split-phase and will output 110-Volt/120-Volt or 220-Volt/230-Volt/240-Volt AC， and operates at 50 Hz or 60 Hz via the SW4 dipswitch on the DC side of the product. This means that this inverter works internationally and is operable with nearly any electrical system on the planet. The split phase 110-Volt/120-Volt/220-Volt/240-Volt split phase inverter is capable of producing 2 legs of 110-Volt， making this inverter perfect for home and shop applications with a 220 panel in place. The 4000-Watt inverter is also built to withstand reasonable heat and temperature fluctuations because of its over-temperature protection and dual thermally-controlled fans and its protected from humidity or airborne dust and dirt by virtue of its marine-coated (or conformal-coated) boards. This inverter provides reliable power needed in any RV， boat， camping， business or residential emergency backup power application and built with a 48-Volt DC input for more efficiency.
