Deye 10–15 kW Three-Phase Low-Voltage Solar Inverter

This is Deye's three-phase solar inverter for a building already wired with a 220V or 230V three-phase supply, sold here in 10, 12 and 15 kW ratings. All three send everything the panels make straight into the building and the grid, with no battery involved, at a weighted European efficiency of 98%. The cabinet is identical across the range, so sizing up later changes nothing about the bracket or the cable run.

True of every rating

• Connects to a 127/220V or 133/230V three-phase supply on 3L/N/PE, at 50 or 60 Hz
• Two panel inputs, each accepting up to 26 A, with an 800 V ceiling and a 250 V start-up
• 98.6% peak efficiency, 98% European weighted, and current distortion held under 3%
• Sealed to IP65 and cleared to 4,000 m altitude, so an outside wall in a hot yard is fine (up to 60C)

10 kW three-phase solar inverter for a villa or small shop rooftop

The 10 kW takes up to 13 kW of panels, which leaves room for the usual oversizing, and pushes 26.3 A per phase into the building. Its full load window opens at 250 V, the lowest of the three, so short strings and dull winter mornings still hold rated output. Its input and output apparent power limit is 11 kVA. Choose it when the three-phase daytime load sits near 10 kW.

Max panel input: 13 kW · Rated AC output current: 26.3 A · Full-load MPPT window: 250-700 V · Max input/output apparent power: 11 kVA

Model code: SUN-10K-G05-LV

12 kW three-phase string inverter for a workshop or small factory

The 12 kW sits in the middle of the range: 15.6 kW of panels, 31.5 A per phase and 13.2 kVA of apparent power. Its full load window starts at 300 V, so strings need to be a little longer here than on the 10 kW before the inverter will hold full output. It is the usual pick for a workshop or a pump shed whose daytime draw runs between 10 and 13 kW.

Max panel input: 15.6 kW · Rated AC output current: 31.5 A · Full-load MPPT window: 300-700 V · Max input/output apparent power: 13.2 kVA

Model code: SUN-12K-G05-LV

15 kW three-phase solar inverter for a small commercial rooftop

The 15 kW is the top of this range and takes 19.5 kW of panels, 6.5 kW more than the 10 kW unit, at 39.4 A per phase. Plan longer strings for it: full output needs at least 375 V from the array. Active and apparent power are both 15, so there is no reserve above the rating, worth knowing if motors dominate the load. Cabinet and weight match the smaller two.

Max panel input: 19.5 kW · Rated AC output current: 39.4 A · Full-load MPPT window: 375-700 V · Max input/output apparent power: 15 kVA
