Deye SUN-12K-SG04LP3-EU 12kW Three-Phase Hybrid Inverter (48 V)

The SUN-12K-SG04LP3-EU is a 12 kW three-phase hybrid inverter from Deye for homes, offices, and businesses with a three-phase supply that want solar and battery backup on all three phases. It runs on a 48 V low-voltage battery bank at up to 240 A charge and discharge, with transformer isolation.

It supports 100% unbalanced output, with each phase able to deliver up to half the rated power, which matters in real buildings where loads are never shared evenly across phases.

Two MPPTs accept up to 800 V and track from 200 to 650 V. It can charge the battery from a diesel generator, retrofit an existing solar system by AC coupling, and use six time periods for battery scheduling. Up to 10 units run in parallel, on or off grid.

The IP65 housing allows outdoor installation, operating from -40 to 60 °C, and peak efficiency is 97.6%. We size the inverter, battery bank, and solar array to your actual loads and backup hours, and handle the installation, earthing, and surge protection.
