Deye SUN-50K-SG01HP3-EU-BM4 Hybrid three-phase inverter 50KW

DEYE SUN-50K-SG01HP3-EU-BM4 is a professional three-phase hybrid solar inverter with a rated power of 50 kW, designed for large photovoltaic (PV) systems with batteries and grid integration. This model is ideal for commercial rooftop installations, small industrial sites and larger multi-phase residential systems where high reliability, energy independence, stable self-consumption management and backup power are required.

The inverter combines functions for managing solar production, charging/discharging batteries, and automatic transition to backup mode in the event of a grid outage, making it a universal solution for modern energy projects.

Main advantages

• Hybrid architecture. The SUN-50K combines PV generation, battery storage, and backup power capability in a single device — without the need for additional controllers.
• 4 independent MPPT inputs. With up to 4 MPPT trackers and 8 DC inputs for panels, the inverter ensures maximum energy extraction from photovoltaic arrays, even when part of the roof has a different orientation or shading.
• High efficiency. With a maximum efficiency of 97.6% and a Euro efficiency of around 97%, the model minimizes energy conversion losses and increases system yield.
• Flexible connectivity. Supports on-grid energy with export, self-consumption and backup mode, making it suitable for various types of system architectures.
• Parallel operation. Up to 10 inverters in parallel — ability to scale power when needed for larger PV systems or higher loads.
• Robust protection and durability. Comprehensive protection includes anti-islanding protection, overvoltage protection, reverse connection, insulation fault and residual current monitoring. IP65 housing allows installation in semi-enclosed or open locations.
