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(5-18)K02-NV-YD-L is a three-phase hybrid energy storage inverter (SOLARATOR series) for residential and light commercial sites needing solar, storage and backup on one platform, available from 5 to 18 kW. It runs 2 MPPTs with 2–4 PV strings depending on model, accepts up to 1000 V and 21 A per input, supports PV oversizing to 160% of rated DC power, and reaches 97.5% max efficiency (97.0% EU). It works with low-voltage (40–60 V) Li-ion or lead-acid batteries across two battery ports, supports both DC and AC coupling, and includes a native backup output with <10 ms switchover. Standard protection covers an integrated DC switch, residual current detection, insulation resistance monitoring, DC reverse-polarity and anti-islanding, in an IP66 enclosure rated for outdoor install.
