Deye SUN-50K-SG01HP3-EU-BM4 50kW Three-Phase High-Voltage Hybrid Inverter

The SUN-50K-SG01HP3-EU-BM4 is a 50 kW three-phase hybrid inverter from Deye for commercial and industrial sites: factories, hotels, hospitals, schools, and office blocks. It works with high-voltage lithium battery systems such as Deye's BOS-A stacks, which carry large power at lower current than 48 V banks, reducing cable sizes and losses.

The BM4 version has four MPPT trackers for large or mixed-orientation solar arrays, and the inverter balances unequal loads across the three phases. It can integrate a diesel generator, charging the batteries from it and reducing generator run hours and fuel use.

It is part of Deye's 29.9–50 kW high-voltage hybrid range. Systems of this size need proper design: we survey your loads, generator, and roof or ground space, then size the array, battery stack, and protection, and commission the system with monitoring.
