The micro-inverter offers unique technology that enables much improved solar energy harvest, increased reliability, simplified installation and efficient management of solar power systems. Each micro-inverter is individually connected to up to four PV module in the solar panel array.This unique conflguration achleves Maximum Power Point Tracking (MPPT) at the PV module level,thus eliminating single-point failure,minimizing the effect of shading,soiling,orientation or PV module ageing, and improving the system's efficiency by up to 30%.
