Description
The Deye SUN-25K-G04 is a commercial-grade 25 kW three-phase grid-tied string inverter designed for direct solar power feed-in without battery storage.Engineered for high yield in residential and commercial PV setups, it features 2 independent MPPT trackers with a maximum efficiency of 98.6%.Equipped with a low start-up voltage (250V), wide MPPT voltage range (200V–850V), Type II DC/AC surge protection, and intelligent string monitoring, it delivers reliable, long-term power generation and easy maintenance.
Key Features & Benefits
Dual MPPT Tracking:Built with 2 independent MPP trackers (3 strings per MPPT capacity) to maximize solar harvesting across complex roofs and varying panel orientations.
High Conversion Efficiency:Achieves up to 98.6% maximum efficiency (97.8% European efficiency) to minimize energy power losses.
Wide MPPT Operating Range:Operates effectively across a 200V–850V MPPT range with a low 250V start-up voltage for longer daily operational hours.
Integrated Type II Surge Protection: Features built-in Type II DC and AC surge arresters to protect against electrical surges and lightning transients.
Zero Export & VSG Support:Compatible with external energy meters or CTs for zero-feed-in control and Virtual Synchronous Generator (VSG) grid support functions.
Intelligent Air Cooling:Built with smart fan cooling and an IP65 protection rating for long-term outdoor operation.
