The Deye SUN-30K-SG01HP3-EU-BM3 is a powerful three-phase hybrid inverter (30 kW) built for high-demand residential, multi-unit, and small C&I PV systems that require high-voltage battery storage, flexible retrofit options, and stable backup/off-grid capability. It supports both DC-coupled and AC-coupled system designs, making it ideal for new installs as well as upgrading existing PV sites with energy storage. 

Why installers choose it

• High-voltage battery integration (160–800 V): higher system efficiency and lower currents for large ESS builds. Hybrid flexibility (retrofit-ready): supports DC coupling + AC coupling to add storage to existing solar systems.

• Parallel scalability: up to 10 units in parallel for on-grid and off-grid operation; supports multiple batteries in parallel. 

• Backup/off-grid performance: supports on-grid/off-grid operation with 1.5× peak power (10 s) for demanding loads. 

• Generator (diesel) support: can store energy from a diesel generator (useful for hybrid microgrid sites). 

• Advanced time-of-use control: up to 6 time periods for battery charging/discharging scheduling.
