The Sigenergy Sigen PV H2 is a multi-MPPT string inverter, available both in the 333,3 kW and 360 kW version, and it is part of the Sigen Utility PV Inverter series, designed for utility-scale ground-mounted PV systems with DC voltage up to 1,500 V. The inverter features 14 independent MPPTs, each supporting up to 2 PV strings thanks to the high levels of current supported, for a total of 28 strings connectable.
On the AC side, the Sigen PV 370H2 delivers a rated output power of 333.000 W, while the Sigen PV 400H2 delivers a rated output power of 360.000 W, both with an output voltage of 800 V (3W+PE). Maximum efficiency reaches 99%, with a European efficiency of 98.8%.
Built-in safety functions include a DC switch, PV/output terminal overtemperature protection, anti-islanding protection, AC overcurrent protection, DC reverse-polarity protection, insulation monitoring, and residual current monitoring. DC surge protection is Type II as standard (Type I optional), while AC surge protection is Type II; arc-fault detection (AFCI) is available as an option.
The inverter can operate within an ambient temperature range from -30 °C to 60 °C, has an IP66 protection rating and a smart air cooling system. The anti-corrosion class is C5-M as standard (C5-H optional). Dimensions do not go over half a cubic meter, with a weight of 150 kg.
It communicates via Fast Ethernet, AC-side power line communication (PLC) and WLAN. The management is performed through a dedicated app and an integrated LED display.
