Deye 6–8 kW Three-Phase Low-Voltage Solar Inverter

The 6 kW and 8 kW models here are three-phase solar inverters made for low-voltage grids running at 127/220 V or 133/230 V. Both are 11 kg wall units with two MPPT trackers and no fan, which makes them practical over a shop counter or in a small workshop where nobody wants a noisy box overhead. The difference between the two is mainly how much panel each one will swallow.

True of every rating

• Both weigh 11 kg in a 283 x 463 x 178 mm case, so the same pair of bolts holds either one.
• Two MPPT trackers with a 200 to 700 V window and a 300 to 700 V full-load band.
• Wakes at 250 V and accepts up to 800 V from the array.
• IP65 sealed with natural cooling, meaning no fan to clog with dust.

Choose your rating

6 kW three-phase solar inverter for a 7.8 kW shop or villa array

Rated 6 kW with 7,800 W of panel capacity and 15.8 A per phase. Both of its trackers take 20 A, so the array wants splitting fairly evenly between them. European weighted efficiency is 97.8% and maximum output fault current is 30.2 A. Pick this one when the roof is a single clean plane and the load is lighting, fans and a couple of small motors.

Rated AC power: 6 kW · Max PV input power: 7,800 W · Max AC output current: 15.8 A · European efficiency: 97.8%

8 kW three-phase solar inverter with 20 A and 26 A MPPT inputs

Rated 8 kW and taking 10,400 W of panels, with 21 A per phase. Its two trackers are deliberately unequal, 20 A on one and 26 A on the other, which lets you hang a longer string on the bigger input instead of splitting the roof down the middle. European weighted efficiency is 98%, a little ahead of the 6 kW model, and maximum output fault current is 40.2 A.

Rated AC power: 8 kW · Max PV input power: 10,400 W · Max AC output current: 21 A · Max PV input current: 20 A + 26 A
