Solar Inverter is an important component in any solar power system. Its basic function is to change the variable Direct Current (DC) output of the solar panels into Alternating Current (AC). The various other components connected in the circuit assist in the conversion.
A) Off Grid Inverters:- These inverters are used in isolated systems wherein the inverter is fed DC power from a battery bank. This battery bank is charged by solar panels.
B) Grid Tie Inverters:- An inverter which is connected to the grid can be said to be a grid tie inverter. The grid tie inverters are designed to automatically shut down after sensing loss of supply from the utility.
C) Battery backup Inverters:- These special types of inverters are especially designed to draw energy from a battery. The battery charge is maintained by using an onboard charger and the extra energy is exported to the grid.
D) Micro Inverters:- These inverters are the latest in the solar industry. They are small & compact in size and yet are packed with a lot of performance & promise.
