The SMT G2 Series string inverters (35–80kW) are designed for C&I applications, delivering high energy yields and exceptional power density. The 35–50kW models are tailored for low-voltage (127/220Vac) installations. Across the range, support for high-power PV modules is ensured through multiple MPPTs and up to 21A input current per string, delivering consistently optimized performance. The SMT G2 Series comes in two designs: a compact, ultra-low-noise version for the 35/37.5/60kW models, and a reinforced, high-power-density version for the 50/75/80kW models. For reliability, the series includes Type II surge protection on both DC and AC sides, with optional AFCI for enhanced protection.
