The M2HT series has a power range of 75–125 kW and is the company’s first product in the 125 kW power class.
Chinese energy storage solutions company Solinteg has released a new series of hybrid inverters designed for the commercial and industrial (C&I) market.
The series, called M2HT, offers power ratings of 75 kW, 80 kW, 99 kW, 100 kW and 125 kW, marking the company’s first entry into the 125 kW power class. It features 200% oversized PV capacity, with corresponding solar inputs of 150 kW, 160 kW, 200 kW, 200 kW and 250 kW.
“The core of the new platform is a 300 A charge/discharge capacity, combined with two independent battery inputs,” the company said. “The system is designed to support large size lithium cells, such as 314 Ah and 628 Ah units. Each battery input is managed by its own battery management system (BMS), allowing the inverter to accommodate phased capacity expansion and battery modules of different brands or specifications to operate in parallel without interdependence.”
All systems in the series are equipped with six Maximum Power Point Trackers (MPPTs). The 75 kW, 80 kW and 99 kW models support two strings per MPPT, while the 100 kW and 125 kW models support three strings per MPPT. For all models, the MPPT operating range is 160 V to 950 V. A built-in energy management system provides scheduling, peak shaving and dynamic price integration, with optional PV generation forecasting.
“To ensure continuity of supply, the inverter supports 100% three-phase unbalanced loads, half-wave loads and transitions of less than 20 ms from mains to backup mode. On the backup side, it can provide 150% overload for ten seconds, allowing it to absorb the inrush current of motor-driven and inductive equipment,” Solinteg said. “Additional features include automatic control of the diesel generator and smart load management, designed for environments with mixed energy sources or irregular demand patterns. The enclosure is IP66 rated and includes a 330 A contactor, with an optional AFCI module.”
The inverters have the dimensions 122.6 cm x 93.2 cm x 35.6 cm and weigh 168 kg. They operate at temperatures from -30 C to 60 C and humidity up to 100%, with a maximum operating altitude of 3,000 m. The company notes that the series is adaptable to a wide range of distributed energy scenarios, from industrial and commercial operations with variable demand to agricultural facilities with seasonal consumption, as well as emerging microgrids that require coordinated control of PV, storage and diesel sources.
