At the heart of the grid-connected system, the inverter extracts as much DC power as possible from the PV array and converts it into AC power at the right voltage and frequency for feeding into the grid or supplying domestic loads. The inverter is the key item of equipment for converting DC. VA defined the rating of Inverter. Most of the electrical rating is defined in terms of voltage and current (VA) because of AC power factor of current is decided by the load connected. AC Power = V X I X pf. Since the load power factor is not known while the Electrical. We are all aware of the use of electricity nowadays & it's an important part of our life. We are using Grid Electric Power supply provided by the Government or by some Private agencies in multistoried apartments. In India due to frequent power supply. In India, approximately 1 crore inverters are sold every year in India. Inverters are being sold which have both normal inverters and solar inverters. A normal inverter means that it will be used for charging of the battery by using electricity only, whereas a solar. While you are planning to buy a heavy capacity inverter for big homes where the average power consumption is 2,000 watts (2KW), below are the main decision-making factors, you should keep in mind.
