The Felicity 10kva 48v power inverter is a great fit for installations requiring large amount of backup power or large solar panel arrays because of its high efficiency in DC-AC conversation and vice versa. The automatically adjusted charge current helps prolong the longevity of a battery as well as protects it from overcharging. It can start electric motors of up to 3HP. Inverters are used as emergency backup when there is power outrage. It turns on the electrical appliances when the main supply is off. The function of the inverter is to convert direct current (DC) to Alternating current (AC). DC is the current produced from the battery or solar panel. Inverters are also called AC Drives, or VFD (Variable frequency drive). They are electronic devices that can turn DC (direct current) to AC (Alternating current). It is also responsible for controlling speed and torque for electric motors. There are 3 major types of inverters:1. Pure Sine wave inverter2. Modified Sine wave inverter3. Square wave inverter Inverters are used in the following areas: home, offices, church, mosques, hospitals, hotels, school etc.
