The Deye SUN-30K-SG02HP3-EU-AM2 is a 30 kW three-phase high-voltage hybrid inverter built for larger residential, multi-unit and small C&I PV systems that need strong PV harvesting, HV battery storage, and reliable backup/off-grid capability. With 3 MPPT (6 strings) and AC coupling support, it is a great choice for new hybrid installations and for upgrading existing solar systems with storage—without rebuilding the PV side. 

Why installers choose it

• High-voltage battery platform (160–700 V) for higher efficiency and lower currents in larger ESS builds. 

• 1× battery input (HV) with up to 75 A charge / 75 A discharge (self-adaption to BMS via CAN/RS485). 

• 3 MPPT / 6 strings (2+2+2) for flexible string layouts across multiple roof orientations and partial shading. 

• 100% unbalanced output for real-world 3-phase loads (each phase supported). 

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

• Advanced energy scheduling: up to 6 time periods for battery charging/discharging + diesel generator energy storage support.
