Product Description:

Description:

 

A solar micro-inverter, converts direct current (DC) electricity from a single solar panel to alternating current (AC). The electric power from several micro-inverters is combined and fed into an existing electrical grid. Micro-inverters contrast with conventional string or central inverter devices, which are connected to multiple solar panels.

 

Characteristic & Advantages:

More Energy Harvest: Distributed MPPT allows10~25% more energy harvest
Simple: Modularized,single ac cable to the house
Reliability: Longer life time and almost 100% operation hours
Security: No high Voltage, makes safter environments
Inteligent : Monitoring each module
Savings: No dc components and significantly save labor cost
