Hybrid Inverter DeyeSUN-15/20K-SG05LP3-EU

Deye SUN-15/20K-SG05LP3-EU is a three-phase hybrid inverter with a power output of 15 kW or 20 kW, designed for larger photovoltaic installations with energy storage. It is suitable for homes with high energy consumption, commercial buildings, farms and small businesses. It combines on-grid and off-grid operation, ensuring independence and continuity of power supply even in the event of a power failure.

Key features and benefits

• AC output power: 15 kW or 20 kW – ideal for larger photovoltaic systems.
• Three-phase operation – even load distribution and compatibility with 3-phase installations.
• On-grid/off-grid hybrid – possibility of feeding surplus energy back into the grid or operating autonomously from batteries.
• Support for 48 V energy storage – works with lithium-ion and lead-acid batteries.
• Two independent MPPTs – maximum efficiency of PV panels with different roof or structure orientations.
• High operating efficiency – up to approximately 97–98% and MPPT efficiency above 99%.
• Possibility of parallel operation of up to 10 devices – easy scaling of the energy system.
• 100% uneven load on phases – stable operation even with different receiver powers.
• IP65 protection rating – safe installation outdoors or in technical rooms.
• Advanced protection – protection against overvoltage, overload, reverse polarity, insulation monitoring, cooperation with BMS.

Application

• Single-family homes with high energy consumption.
• Companies, workshops, shops, offices and service facilities.
• Farms, agritourism, recreational facilities.
• Photovoltaic installations with energy storage and emergency power supply function.
• Modernisation of existing PV systems – addition of hybrid function and batteries.
