Deye 70–110 kW Three-Phase Solar Inverter

This is Deye's heavy end of the three-phase solar inverter range, the box you put on a factory roof, a cold store or a small solar farm feeding a 380/400 V supply. Six ratings share one cabinet, so the choice comes down to how many panels you are connecting and how much current the site can take. Every unit runs on the grid alone, with no battery involved.

True of every rating

• One cabinet across all six ratings: 824 x 516 x 312.7 mm and 81 kg, so the mounting frame and the lifting plan never change
• Sealed to IP65 and rated from -25C to 60C, which means it can hang on an outside wall in Gulf or Levant heat
• Approved for sites up to 4,000 m above sea level, covering highland projects in Africa and the Levant
• Current distortion stays under 3% THD, with anti-islanding, residual current detection and thermal protection built in

70 kW three-phase inverter for a factory roof of about 105 kW

The entry point of the range. It accepts up to 105 kW of panels across four independent trackers, so a roof split over two or three orientations still gets tracked properly. Output tops out at 116.7 A per phase, with 106.1 A at the rated point, and the strings can run as high as 1,100 V. Its full-load tracking window is 570 to 850 V, the roomiest of the four-tracker units.

Rated AC output: 70 kW · Max PV input: 105 kW · MPPT trackers: 4 · Max AC output current: 116.7 A

Model code: SUN-70K-G03

75 kW string inverter, 112.5 kW of panels on four trackers

A half step up from the 70 kW for sites where the roof takes a few more strings. It handles 112.5 kW of panels and 82.5 kVA of apparent power, giving 125 A maximum per phase against 113.6 A rated. Deye lists its rated PV input voltage at 720 V and its full-load tracking window at 610 to 850 V, so it prefers longer strings than the 70 kW does.

Rated AC output: 75 kW · Max PV input: 112.5 kW · Apparent power: 82.5 kVA · Max AC output current: 125 A

Model code: SUN-75K-G03

80 kW three-phase inverter for 120 kW of panels, 133.3 A out

The largest of the four-tracker units. It takes 120 kW of panels, rated at 88 kVA, and pushes up to 133.3 A per phase with 121.2 A at the rated point. Its full-load tracking window starts at 650 V, the highest in the range, so strings need to be long enough to sit above that before it delivers full output. Cabling and breakers should be sized for the 133.3 A figure.

Rated AC output: 80 kW · Max PV input: 120 kW · Apparent power: 88 kVA · Full-load MPPT window: 650-850 V

Model code: SUN-80K-G03

90 kW solar inverter with six MPPT trackers and 135 kW PV input

This is where the range switches to six trackers, so a complicated roof with six different string groups can go on one machine. It accepts 135 kW of panels and 99 kVA, delivering up to 150 A per phase. The six-tracker units also drop the maximum string voltage to 1,000 V and narrow the tracking window to 200 to 850 V, which changes how strings are laid out compared with the 70 to 80 kW units.

Rated AC output: 90 kW · Max PV input: 135 kW · MPPT trackers: 6 · Max PV input voltage: 1,000 V

Model code: SUN-90K-G03

100 kW three-phase inverter, 150 kW of panels on six trackers

A 100 kW machine sharing the six-tracker platform with the 90 and 110 kW. It carries the highest panel ceiling in the range at 150 kW, tracks between 200 and 850 V and accepts strings up to 1,000 V. Worth knowing before you choose: Deye's table gives the 100 kW and the 110 kW the same 150 kW input ceiling and the same output current column, so the honest difference between them is the 100 kW rated output itself.

Rated AC output: 100 kW · Max PV input: 150 kW · MPPT trackers: 6 · MPPT window: 200-850 V

Model code: SUN-100K-G03

110 kW inverter, the largest rating in Deye's G03 string range

The top of the range at 110 kW of rated AC output, for the largest roofs and ground mounts on a 380/400 V connection. It shares the six-tracker cabinet with the 100 kW model, along with the 150 kW panel ceiling, the 200 to 850 V tracking window and the 1,000 V string limit; the datasheet lists no separate current figures for it. Pick this one when the connection agreement allows the extra 10 kW of export.
