Deye 30–50 kW Three-Phase Solar Inverter

The Deye G04 three-phase solar inverter is a grid-tied machine for commercial roofs: it turns panel output into 400 V three-phase power and feeds it straight into the building, with no battery involved. Seven ratings run from 30 kW to 50 kW, and the practical difference between them is how much panel each one can take and how many separate roof faces it can track independently.

True of every rating

• European weighted efficiency of 98.1% on every rating in the group
• Strings up to 1,100 V, tracked anywhere between 200 V and 1,000 V
• Starts producing from 250 V and holds current distortion below 3%
• IP65 enclosure rated from -25 C to 60 C for rooftop or plant-room mounting

30 kW three-phase grid-tied solar inverter for a 45 kW commercial roof

The entry point of the G04 line takes up to 45 kW of panel against a 30 kW output, a 1.5 times oversize that only the 36 kW model matches. Two independent inputs of 40 A each let you split the array across two roof faces. It puts out 33 kVA and 50 A per phase, peaks at 98.6% efficiency, and weighs 23 kg.

Max panel input: 45 kW · PV inputs: 2 x 40 A · Max AC output current: 50 A · Weight: 23 kg

33 kW three-phase solar inverter, 42.9 kW panel input, two trackers

The 33 kW and the 35 kW share a datasheet column, so their output currents are quoted together rather than separately. What clearly separates them is the array: this one is specified for 42.9 kW of panel, 2.6 kW less than the 35 kW. Two 40 A inputs, full output from 500 V upward, 98.6% peak efficiency, and an altitude rating of 4,000 m for highland sites.

Max panel input: 42.9 kW · PV inputs: 2 x 40 A · Full-load tracking window: 500 to 850 V · Max altitude: 4,000 m

Model code: SUN-33K-G04

35 kW three-phase solar inverter with 45.5 kW of panel input allowed

Two extra kilowatts of output over the 33 kW, and 45.5 kW of panel rather than 42.9 kW. Deye publishes one shared current column for the two models, so we do not quote a separate output current here; the honest difference is rated power and array size. A 23 kg wall case, a pair of 40 A inputs, a 4,000 m altitude rating and 98.6% peak efficiency.

Max panel input: 45.5 kW · PV inputs: 2 x 40 A · Weight: 23 kg · Max efficiency: 98.6%

Model code: SUN-35K-G04

36 kW three-phase solar inverter, 54 kW panel input on two trackers

This is the last of the two-tracker frames and carries the most panel of that group: 54 kW feeding a 36 kW output. Useful on east and west roofs where neither side peaks at once. It delivers 39.6 kVA and 60 A per phase from a 23 kg case, and holds full output from 500 V upward. Fault current is quoted at 104.4 A, which your protection device needs to clear.

Max panel input: 54 kW · Max apparent power: 39.6 kVA · Max AC output current: 60 A · PV inputs: 2 x 40 A

Model code: SUN-36K-G04

40 kW three-phase solar inverter with three MPP trackers, 98.7% peak

A third independent PV input arrives at 40 kW, so the array can be split three ways across roofs facing different directions without losing yield on the shaded one. Peak efficiency also rises to 98.7%. Output is 44 kVA and 66.7 A per phase, panel input is capped at 52 kW, and the unit runs under 50 dB, quiet enough for a plant room next to offices. It weighs 37.1 kg.

Max panel input: 52 kW · PV inputs: 3 x 40 A · Max AC output current: 66.7 A · Noise: under 50 dB

Model code: SUN-40K-G04

45 kW three-phase solar inverter, 58.5 kW panel, three MPP trackers

Three 40 A inputs again, but a much larger frame: 698 by 613 by 236.5 mm and 53.7 kg, the same weight as the 33 kW. It accepts 58.5 kW of panel, gives 49.5 kVA and 75 A per phase, and holds 98.7% peak efficiency. Check the wall or frame it goes on before ordering, because the extra 16.6 kg over the 40 kW changes the fixing.

Max panel input: 58.5 kW · PV inputs: 3 x 40 A · Max AC output current: 75 A · Weight: 53.7 kg

Model code: SUN-45K-G04

50 kW three-phase solar inverter with four MPP trackers, 65 kW panel

The largest rating is the only one with four separate 40 A PV inputs, which suits a site with several roof pitches or a car park canopy in sections. It takes 65 kW of panel, the most in the range, and returns 55 kVA and 83.3 A per phase at up to 98.7% efficiency. Fault current is 145 A, so size the AC protection and cable accordingly.

Max panel input: 65 kW · PV inputs: 4 x 40 A · Max AC output current: 83.3 A · Max apparent power: 55 kVA
