Sigenergy Sigen Hybrid 50M1-HYB Hybrid Inverter 50 kW Three-Phase
The Sigen Hybrid 50M1-HYB is Sigenergy's 50 kW commercial and industrial (C&I) three-phase hybrid inverter in the HYB version, the only one in the range that supports on-grid and off-grid operation with load backup. It combines photovoltaic inverter and battery inverter and connects 4 to 21 SigenStack BAT 12.0 modules through the M2-0.5C-BST / M2-1C-BST battery controllers, with charging and discharging power up to 55,000 W.
The photovoltaic side accepts up to 100,000 Wp on 4 MPPTs (2 strings per tracker, 40 A per MPPT, 160-1,000 V range, maximum DC voltage 1,100 V). Backup switchover takes 0 ms with peak power up to 75,000 W for 10 seconds, and the AC input accepts up to 100,000 VA. Maximum efficiency of 98.6%, IP66 and intelligent air cooling.
