Deye SUN-50K-SG01HP3-EU-BM4 Hybrid Inverter 50kW Three-Phase
The Deye SUN-50K-SG01HP3-EU-BM4 is the flagship three-phase 50kW hybrid inverter of the high-voltage range, aimed at commercial and industrial sites: warehouses, farms, hospitality buildings and storage systems that have to cover serious loads. Its 4 MPP trackers rated 36A each let a single unit handle very large PV arrays spread over different exposures.
It stores energy in a 160-800V high-voltage battery through two independent battery inputs and up to 100A of charge and discharge, with the BMS communicating over CAN. Continuous AC passthrough of up to 200A keeps substantial loads supplied in bypass, while running up to 10 units in parallel scales the system towards the 500kW mark. IP65 enclosure suitable for outdoor installation.
