Deye 5–12 kW Three-Phase Low-Voltage Hybrid Solar Inverter

Deye's SG04LP3 range is a three-phase hybrid inverter for a 400V house or workshop supply, sold in five ratings from 5 kW to 12 kW. Each one runs solar, a 48V battery and the grid together, and carries the load on its own when the grid fails. Picking the rating is really picking two things: how much you can run at once, and how fast the battery refills.

True of every rating

• Runs a 48V battery bank, lead-acid or lithium, over a 40 to 60 V window
• IP65 sealed for an outside wall, fan cooled, and no louder than 55 dB
• Two solar inputs, 97.6% peak efficiency, and an 800 V ceiling on the array
• Handles uneven loads at up to 50% of rated power on any one phase, plus 45 A of grid passthrough

5 kW three-phase hybrid inverter, 48V, for a modest family home

The smallest in the range and the one most three-bedroom homes land on. It charges the battery at up to 120 A and takes 7,500 W of panels, with 10,000 W the largest array Deye allows on it. Output peaks at 5,500 VA, 8.4 A per phase. If your evening load is lighting, a fridge, a couple of air conditioners and a water pump, this is the size that fits.

Max charge and discharge current: 120 A · Max PV input power: 7,500 W · Largest permitted array: 10,000 W · Peak apparent power: 5,500 VA

Model code: SUN-5K-SG04LP3-EU

6 kW three-phase hybrid inverter for a home with two air conditioners

One step up from the 5 kW, and the step is real: 150 A of battery charging instead of 120 A, and 9,000 W of panels instead of 7,500 W. Deye allows a 12,000 W array on it. Peak output is 6,600 VA at 10 A per phase. Worth the difference if you already know the roof will grow, because the extra panel headroom is where the value sits.

Max charge and discharge current: 150 A · Max PV input power: 9,000 W · Largest permitted array: 12,000 W · Peak apparent power: 6,600 VA

Model code: SUN-6K-SG04LP3-EU

8 kW three-phase hybrid inverter for a large villa or small workshop

This is the last rating in the range that still uses the narrower solar inputs, 13 A on each of the two trackers. It charges at 190 A, takes 12,000 W of panels and allows a 16,000 W array, reaching 8,800 VA and 13.4 A per phase at maximum output. A good match for a villa running several air conditioners, or a shop with a chiller and a few motors.

Max charge and discharge current: 190 A · Max PV input power: 12,000 W · Largest permitted array: 16,000 W · Max AC output current: 13.4 A

Model code: SUN-8K-SG04LP3-EU

10 kW three-phase hybrid inverter for a big villa or a small business

The 10 kW is where the hardware changes, not just the numbers. Its first solar tracker takes 26 A rather than 13 A, so wider strings can go into it, and the unit adds reverse-polarity protection on the DC side plus insulation monitoring. Charging reaches 210 A, panels 15,000 W, array 20,000 W. Deye lists this rating at 60 Hz nominal, so confirm the grid setting with your installer.

Max charge and discharge current: 210 A · Max PV input power: 15,000 W · PV input current, first tracker: 26 A · Max output fault current: 33.4 A

Model code: SUN-10K-SG04LP3-EU

12 kW three-phase hybrid inverter, the largest in this 5 to 12 kW range

The largest of the five and the one that leaves the most room to grow into. It charges at 240 A, takes 18,000 W of panels and allows a 24,000 W array, with 13,200 VA peak and 18.2 A per phase at the rated output. Like the 10 kW it carries the wider 26 A first tracker, and its output fault rating is 40 A. Deye lists this one at 60 Hz nominal too, so check that against your grid.

Max charge and discharge current: 240 A · Max PV input power: 18,000 W · Largest permitted array: 24,000 W · Max output fault current: 40 A
