As commercial and industrial (C&I) facilities increasingly adopt renewable energy and battery storage, the demand for flexible, efficient and scalable power solutions continues to grow. Addressing these requirements, Deye’s SUN-125K-SG02HP3-EU-GM10 is a three-phase, high-voltage hybrid inverter designed to integrate solar generation, battery storage and AC power management within a single platform.
High-Voltage Battery Integration
The inverter supports high-voltage lithium-ion batteries with a voltage range of 160–1000 V and a maximum charging and discharging current of 200 A, configured as 100 A + 100 A across two battery inputs. Its battery management system (BMS) self-adaptation supports communication with compatible battery systems, enabling coordinated battery operation.
With six programmable time periods for battery charging and discharging, the inverter allows users to configure energy management according to site requirements and solar generation patterns. This flexibility can help commercial facilities optimise battery utilisation based on their electricity consumption profiles and tariff structures.
Efficient Solar Power Conversion
The SUN-125K-SG02HP3-EU-GM10 delivers a rated AC active power of 125 kW and offers a maximum efficiency of 98.70%.
The inverter supports a maximum PV input power of 200 kW, with ten maximum power point trackers (MPPTs). These features provide flexibility in configuring solar arrays for suitable new installations and solar-plus-storage projects.
Additionally, its 100% unbalanced output capability supports applications with uneven loads across three phases. The inverter can deliver up to 1.5 times its rated power for 10 seconds in off-grid operation, helping accommodate short-duration power demands, subject to system design and load characteristics.
Flexible Retrofit and Scalable Design
For facilities with existing solar installations, the inverter supports AC coupling, enabling battery storage integration while retaining suitable existing solar equipment. This provides an option for businesses looking to expand their energy storage capabilities without necessarily replacing their existing solar inverters.
The system supports parallel operation of up to ten units in both on-grid and off-grid applications. It also supports multiple batteries in parallel, subject to equipment compatibility and appropriate system design. In addition, the inverter can store energy from a diesel generator, providing another option for installations incorporating generator-based power supply.
Built for Reliable Operation
The inverter features an IP65 protection rating and intelligent air cooling, with a specified operating temperature range of -40°C to +60°C, with power derating above 45°C. Integrated protection functions include DC reverse-polarity protection, AC overcurrent protection, thermal protection, anti-islanding protection, insulation monitoring and Type II AC/DC surge protection. Arc-fault circuit interruption is available as an option.
Monitoring and communication options include RS485, RS232 and CAN, alongside optional Wi-Fi, Bluetooth, 4G, LAN and GPRS connectivity.
By combining high-voltage battery integration, AC-coupling flexibility, configurable energy management and scalable parallel operation, Deye’s 125 kW hybrid inverter is designed to support a range of commercial and industrial solar-plus-storage applications.
