Commercial and industrial PV solar power system require high-yield PV inverters that are easy-to-install, reliable and user friendly. Therefore our 30-50K LT-G2 series string inverters for solar panel are your best choice combining quality, performance, and reliability within a compact IP66 rated award winning design. Multiple MPPT´s (up to five) allowing up to 150 % oversizing of the PV array ensures complete PV plant design flexibility for all applications regardless of location. With the introduction of our unique shadow management feature, our 30-50K LT-G2 PV inverter will continue to generate high yields under non-ideal conditions without the need for additional DC optimisers, therefore reducing the overall cost of solar energy.
