Solis, celebrating its 20th anniversary, showcased its advanced hybrid inverters for the residential and commercial and industrial (C&I) solar energy systems at REI 2025.
Launched under the S6-EH3P series, its 125 kW smart string hybrid inverter for C&I solar systems integrates battery smart charging/discharging (PCS), PV inversion, on-grid/off-grid and genset switching (STS), and a smart energy management system into a single compact unit.
The inverter supports both DC and AC coupling, enabling flexible retrofits and system expansions. It also offers a three-in-one interface for seamless integration of on-grid PV, wind power, and diesel generators. With a transition time of less than 10 ms between on-grid and off-grid modes, it ensures a continuous and stable power supply.
In addition, the S6-EH3P hybrid inverter is scalable for larger C&I solar applications by supporting multi-unit parallel operation up to 1.25 MW.
The inverter supports up to 2× rated PV input, maximizing solar energy utilization. Each string supports up to 21 A current, ensuring full compatibility with high-power and bifacial 182/210 mm PV modules. It is compatible with 100–314 Ah battery modules, helping reduce overall system costs, and supports fast battery charging with a maximum charging current of 200 A.
Two independent battery ports allow for flexible configurations and easy capacity expansion. The system can deliver 160% overload for 200 ms in off-grid mode, enabling stable startup of heavy loads. Solis’ patented cooling technology ensures reliable operation even under high-temperature conditions.
