12kW Deye SUN-12K-SG05LP3-EU-SM2 Three-Phase Hybrid Solar Inverter – 48V High-Load Power

The 12kW Deye SUN-12K-SG05LP3-EU-SM2 Three-Phase Hybrid Solar Inverter is designed for properties that require three-phase power together with solar generation, battery storage and grid integration.

Its 12kW output provides substantial capacity for larger electrical loads. Unlike single-phase models, its three-phase architecture makes it particularly relevant for properties and businesses operating three-phase electrical systems.

The inverter works with a 48V low-voltage battery architecture, allowing integration with correctly matched lithium battery storage.

Its hybrid design manages energy between solar PV, batteries, utility grid and connected loads. This helps maximise solar utilisation while providing stored-energy and backup capability when correctly configured.

The combination of 12kW power, three-phase output and 48V battery integration makes this model a strong choice for large residences, commercial premises, workshops and other higher-demand solar installations.
