Description
The Deye SUN-20K-G04 is a high-efficiency 20 kW three-phase grid-tied string inverter built for commercial and residential solar projects.Designed for pure solar generation without energy storage, it incorporates 2 independent MPPT trackers with dual string access to maximize performance across complex array layouts.Delivering up to 98.6% conversion efficiency, it incorporates integrated Anti-PID functionality, Type II DC/AC surge protection, zero-export control, and smart string monitoring for dependable long-term operation.
Key Features & Benefits
Dual MPPT Tracking:Built with 2 MPP trackers (2 strings per MPPT) to optimize yield on roofs with multiple pitch angles or light shading.
High Conversion Efficiency:Reaches up to 98.6% max efficiency for superior energy harvest and rapid ROI.
Wide Voltage Range:Wide MPPT operating voltage range with a low startup threshold for extended power output during early morning and late afternoon hours.
Anti-PID Feature:Includes built-in Anti-PID protection to prevent potential-induced degradation and extend PV panel lifespans.
Integrated Type II Surge Protection: Built-in DC and AC Type II surge protection devices protect internal circuits from lightning transients and voltage spikes.
Zero Export & VSG Support:Compatible with external energy meters or CTs for zero-feed-in compliance and Virtual Synchronous Generator (VSG) grid support.
