## Overview

Professional solar installations demand reliable power conversion, and this Chinese-manufactured hybrid inverter delivers exceptional performance for commercial and industrial applications. Engineered with dual MPPT technology, it efficiently manages solar input across a wide 200-650V voltage range while maintaining an impressive 97.6% maximum efficiency rating.

Built for demanding environments, this three-phase unit operates reliably from -40°C to +60°C with IP65 weatherproof protection. The robust design handles up to 800V DC input while delivering clean AC power at 220/380V or 230/400V configurations with only 3% total harmonic distortion. At 35.2 kg, it provides substantial power processing capability while supporting both 50Hz and 60Hz grid frequencies, making it suitable for diverse international markets and hybrid battery-supported installations.

## Frequently asked questions

### Is the Deye SUN 3-12K SG05LP3-EU-SM2 single-phase or three-phase?

Three-phase. The Deye SUN 3-12K SG05LP3-EU-SM2 is recorded with three phases and an AC output of 220/380 V or 230/400 V at 50 Hz or 60 Hz, so it needs a three-phase connection rather than an ordinary single-phase domestic supply. Those paired voltages are two alternative network configurations, not four separate ones.

### What does the 3-12K in the Deye SUN 3-12K SG05LP3-EU-SM2 name mean?

It marks a family rather than one unit: the Deye SUN 3-12K SG05LP3-EU-SM2 designation runs from 3 kW through 4, 5, 6, 8 and 10 kW up to 12 kW. The values held for this entry, two MPPT channels with a 200 V to 650 V window and 800 V maximum DC input, are common to the range.

### Does the Deye SUN 3-12K SG05LP3-EU-SM2 work with a battery?

Yes. The Deye SUN 3-12K SG05LP3-EU-SM2 is listed as a hybrid inverter, meaning battery charging and discharging is handled inside the same box that converts the PV array and ties into the grid. For a three-phase household that removes the need for a separate battery inverter alongside the solar one.

### How many roof orientations can the Deye SUN 3-12K SG05LP3-EU-SM2 handle?

Two. The Deye SUN 3-12K SG05LP3-EU-SM2 has two MPPT channels, which is modest for a designation reaching 12 kW, so an array spread over three or more differently oriented planes has to be grouped onto two trackers. Its tracking window runs from 200 V to 650 V, with an 800 V maximum DC input ceiling.

### How efficient is the Deye SUN 3-12K SG05LP3-EU-SM2?

The Deye SUN 3-12K SG05LP3-EU-SM2 is rated at 97.6 percent maximum efficiency and 97.0 percent European efficiency. The two figures sit unusually close, which points to conversion losses staying near their best across much of the load range rather than only at full output. Total harmonic distortion of the injected current is given as 3 percent.

### Where can the Deye SUN 3-12K SG05LP3-EU-SM2 be mounted?

The Deye SUN 3-12K SG05LP3-EU-SM2 is rated IP65 with a declared operating range of -40 to +60 degrees Celsius, so an outdoor wall in a cold or a hot climate stays within specification. At 35.2 kg it is noticeably heavier than a single-phase hybrid and is best lifted onto its bracket by two people.
