Solis is a major brand for solar inverters, which are crucial components of solar power systems. They produce a wide range of inverters for residential, commercial, and utility-scale applications, including single-phase, three-phase, and hybrid inverters. They also offer accessories like data logging sticks and monitoring solutions.
The Solis S6-EH3P (30-50)K-H-ND SOLARATOR is a three-phase high-voltage hybrid (energy storage) inverter spanning 30 to 50 kW, built for commercial and industrial PV-plus-storage systems in cold and exposed climates. Rated to −25 °C and free of any outdoor LCD that could fade, ice over or fail, it uses an LED indicator with setup and monitoring through Bluetooth and the SolisCloud app. It runs 3–4 MPPTs (up to 8 strings) at 40 A per input, a 1,000 V max input voltage and a 150–850 V MPPT range, accepting up to 2× rated PV input. It works with 150–800 V Li-ion batteries over CAN/RS485 across two independent battery ports (100–280 Ah modules, fast charging up to 140 A), delivers up to 97.8% max efficiency (97.4% EU), and offers a three-in-one interface for grid PV, wind and diesel-generator input. It has backup switchover <10 ms, both DC and AC coupling, integrated DC switch, factory-fitted Type II DC/AC surge protection, intelligent fan-cooling and an IP66 enclosure.
