What is Micro-Inverter?
Micro-Inverter is an innovative solution for solar installations. It directly converts the DC voltage solar power from PV-panels into standard AC grid voltage (230V/50Hz). The micro-inverter is usually mounted directly at the solar panel. The input (DC) is 20V to 50V. The power of micro-inverter is usually 250W. (The inverters bellow 1kW of power are in general called micro-inverters).
There are many good reasons why to use the micro-inverter at the photovoltaic installation.
