Three-phase hybrid inverter — Deye SUN-20K-SG01HP3-EU-AM2
The Deye SUN-20K-SG01HP3-EU-AM2 is a three-phase high-voltage hybrid inverter designed for commercial and large residential PV systems. It combines DC-coupled and AC-coupled modes for retrofit and new installations, supports parallel scaling and multi-battery configurations, and offers robust protection and wide temperature tolerance for demanding PV + battery storage applications.
Applications and use cases
This 20 kW hybrid inverter is built for three-phase distribution in commercial rooftops, small commercial sites and larger residential installations that require integrated PV and battery storage. Its DC-coupling and AC-coupling capability make it suitable for retrofitting existing solar arrays as well as new system designs, and support for diesel-generator charging makes it useful in off-grid or hybrid backup scenarios.
- Three-phase inverter architecture for commercial and multi-phase residential systems
- DC-couple and AC-couple operation for retrofit and new PV + storage systems
- Supports storing energy from diesel generator for hybrid backup setups
- Parallelable design for larger installations — up to 10 units in parallel for on-grid and off-grid operation
