Manufacturer Involar

The INVOLAR MAC250 Microinverter offers the latest technology in power inverters. Each Microinverter is connected to one PV module in the solar panel array. Unlike conventional Inverters, in the event of single panel failure the remaining panels continue to produce power.

By performing Maximum Power Point Tracking (MPPT) at the PV module level,  INVOLAR Microinverters minimize the effects of shading, debris, snow, panel orientation differences and mismatches or PV module aging, improving the system’s  energy harvest and customer income by up to 25% over the system lifetime.

These advantages in combination with a much longer product warranty, enables an  INVOLAR Microinverter system to greatly improve the end customer’s Return On Investment. 

The company proudly stands behind the M250 with a solid 25-year limited warranty.
