Deye introduces its latest innovation in commercial and industrial (C&I) energy solutions — the SUN-100/125K-SG02HP3-EU-GM8/GM10 series, designed to meet the growing demand for high-performance, flexible, and scalable energy systems.
Available in three configurations — 100kW with 8 MPPTs, 100kW with 10 MPPTs, and 125kW with 10 MPPTs — the series is engineered to optimize solar generation even in challenging rooftop environments. Each unit features up to 10 independent MPPTs, with 2 strings per MPPT and a maximum input current of 21A per string, making it fully compatible with high-power PV modules. With support for up to 200% PV oversizing and 160% PV input capacity, the inverter maximizes solar energy harvesting and system yield.
The inverter supports parallel operation of up to 10 units, allowing system expansion up to 1.25MW. This scalability makes it ideal for factories, commercial buildings, and large-scale distributed energy projects. Its AC coupling capability enables seamless upgrades of existing solar systems without major modifications.
With an IP65 protection rating and a maximum efficiency of 98.7%, the system ensures reliable performance across a wide range of indoor and outdoor environments. Built for mission-critical applications, the inverter provides UPS-level seamless switching between on-grid and off-grid modes, ensuring uninterrupted power supply during grid outages. It also delivers 150% peak off-grid output for up to 10 seconds, and supports diesel generator integration for automatic backup power during prolonged outages.
Through a built-in Time-of-Use (ToU) strategy, the system allows up to six customizable time slots for battery charging and discharging, enabling users to optimize energy consumption based on local tariff structures. AI-driven optimization further enhances performance by dynamically adjusting charge and discharge strategies in response to fluctuating electricity prices.
The inverter supports a wide battery voltage range from 160V to 1000V, ensuring compatibility with mainstream high-voltage energy storage systems. With dual battery ports and 100A + 100A charge/discharge current, the system enables efficient energy storage and fast response to load demands.
To meet diverse application needs, the inverter can be paired with Deye’s diversified high-voltage battery portfolio: the GE-F240/F256 series (314Ah) for outdoor all-in-one cabinets (16.08kWh per unit, up to 241/257kWh single-cluster); the BOS-B Pro (314Ah) for high-capacity indoor projects (up to 257kWh); the BOS-A series (200Ah) for precise capacity configuration (7.68kWh per unit, up to 161kWh single-cluster); and the GB-W (235Ah) stackable solution (12.03kWh per unit, up to 192kWh).
Deye is a supplier in the energy-storage value chain covered by the Besscare Selection.
