Deye 60–80 kW Three-Phase Solar Inverter

A three-phase solar inverter of this size goes on the wall of a factory, a cold store or a school and sends the whole roof straight into the building's own supply. Four ratings share one 53.7 kg cabinet, so the frame, the cabling method and the spares stay the same whichever one is specified. Panels connect at up to 1,100 V, which keeps string counts and cable runs down on a large roof.

True of every rating

• One 53.7 kg cabinet across all four ratings, IP65 sealed and fan cooled at 55 dB or less
• Panel input to 1,100 V with tracking from 200 V, so long strings are allowed
• Rated to 4,000 m altitude and ambient temperatures of -25 to 60 degrees C
• Three-phase 220/380 V or 230/400 V connection, wired 3L/N/PE

60 kW three-phase inverter for a mid-size commercial roof

The smallest of the four, rated 60,000 W with 66,000 VA available and 90.9 A per phase. Its efficiency sits a shade below its siblings, at 98.6% peak and 98.0% European weighted. It holds full output from 490 V upward on the tracker, the widest window in the group, which leaves the string designer the most room. Panel input is capped at 90,000 W, half as much again as the AC rating.

Rated output: 60,000 W · Max efficiency: 98.6% · Max PV input: 90,000 W · Full-load tracker window: 490-850 V

Model code: SUN-60K-G04P3-EU-AM4

70 kW three-phase inverter carrying 105 kW of panels on one unit

Rated 70,000 W and 77,000 VA, giving 106.1 A per phase, with peak efficiency of 98.7% and 98.1% European weighted. Full output needs 570 V or more on the tracker. Panel input is capped at 105,000 W. Case, weight and altitude rating match the 60 kW exactly, so a site laid out for one takes the other with no change to the mounting or the cable entry.

Rated output: 70,000 W · Max PV input: 105,000 W · Rated output current: 106.1 A · Full-load tracker window: 570-850 V

Model code: SUN-70K-G04P3-EU-AM4

75 kW three-phase inverter built around a 720 V string design

Rated 75,000 W with 82,500 VA and 113.6 A per phase. This is the first of the four sized around a 720 V nominal panel voltage rather than 600 V, and it wants at least 610 V on the tracker to hold full output, so the strings are designed longer. Panel input is capped at 112,500 W. Peak efficiency is 98.7%, European weighted 98.1%.

Rated output: 75,000 W · Nominal PV voltage: 720 V · Max PV input: 112,500 W · Full-load tracker window: 610-850 V

Model code: SUN-75K-G04P3-EU-AM4

80 kW three-phase inverter, the largest here at 120 kW of panels

The biggest of the family at 80,000 W, 88,000 VA and 133.3 A per phase, and that current figure is the one to check against the incoming breaker and cable before ordering. Panels can total 120,000 W. Full output needs 650 V or more on the tracker, the narrowest window of the four. Efficiency is 98.7% peak and 98.1% European weighted, in the same 53.7 kg case.

Rated output: 80,000 W · Max AC output current: 133.3 A · Max PV input: 120,000 W · Full-load tracker window: 650-850 V
