Deye 23–30 kW Three-Phase Low-Voltage Solar Inverter
Deye 23–30 kW Three-Phase Low-Voltage Solar Inverter
23-30 kW low-voltage three-phase inverter for a workshop or farm
A three-phase low-voltage solar inverter built for grids that run at 127/220 V or 133/230 V rather than the 230/400 V used in Europe and the Gulf, which is what the LV in the name refers to. It suits a workshop, a farm or a small commercial building of roughly 23 kW to 30 kW, feeding the building first and the grid after. Fitting a standard 400 V model to one of these supplies does not work, which is the reason this version exists.
One machine covering the 23 kW to 30 kW band on a 127/220 V three-phase supply. Panels can reach 800 V, tracking runs from 200 V to 700 V and it needs 250 V on the strings before it starts producing. It weighs 37.1 kg in a 434 x 570 x 243 mm case and cools with a fan, so it sits at about 65 dB, better placed on a plant room wall than beside an office window. Five-year warranty.
