Solis inverters are designed and manufactured by the Ginlong Company of China. They are a long established family owned and operated firm, just like Si Clean Energy and we share many of the same values. Solis inverters are built with European quality and European performance. In fact during exhaustive testing in our lab we discovered that their Maximum Power Point Tracker (MPPT) performance sets the benchmark. Priced significantly lower than European brands, Solis inverters are recommended by Si Clean Energy as the “bridge to the solar future”.
