## Overview

Engineered for commercial and large residential solar installations, this three-phase solar inverter delivers impressive power handling capabilities with its 33.75kW nominal output and peak capacity of 37.125kW. The dual MPPT technology maximizes energy harvest from solar arrays, supporting DC voltages from 200V to 1000V with up to 40A input current per channel.

What sets this inverter apart is its exceptional 98.6% maximum efficiency rating, ensuring minimal energy loss during DC to AC conversion. The robust IP65-rated enclosure weighs just 28.7kg despite its industrial-grade construction, making installation manageable while providing reliable outdoor protection. Operating across a wide temperature range from -25°C to +60°C, it maintains consistent performance in challenging environmental conditions with low 3% total harmonic distortion for clean power output.

## Frequently asked questions

### What AC power is recorded for the Deye SUN30-33-36KG04?

The Deye SUN30-33-36KG04 designation names three ratings, 30, 33 and 36 kW. The figures stored for this entry are 33,750 W of nominal AC power and 37,125 W maximum, ten percent above nominal. They fall inside that span without matching one of the three named ratings exactly, so the rating of the specific variant is worth confirming.

### How should an array be split across the two MPPT inputs of the Deye SUN30-33-36KG04?

The Deye SUN30-33-36KG04 has two MPPT channels, each accepting up to 40 A of DC input current. Forty amps per input leaves room for several strings in parallel, so an array of this size is normally divided into two groups by orientation. The DC cabling and protection on each input must be sized for the full 40 A.

### Can the Deye SUN30-33-36KG04 work with short strings?

Not very short ones. The Deye SUN30-33-36KG04 starts tracking at 200 V, so every string has to stay above 200 V even on a hot afternoon when module voltage sags; a handful of modules in series drops out of the window. At the other end it tracks to 1000 V and withstands 1100 V of DC input.

### Is the Deye SUN30-33-36KG04 galvanically isolated from the grid?

No. The Deye SUN30-33-36KG04 is recorded as a non-isolated inverter, meaning there is no transformer between the array and the grid. Leaving that stage out saves weight and a conversion step, which helps explain its 98.6 percent maximum and 98.1 percent European efficiency, but the modules chosen must be suitable for a transformerless connection.

### Does the Deye SUN30-33-36KG04 work on both 50 Hz and 60 Hz grids?

Yes. The Deye SUN30-33-36KG04 is declared for 50 or 60 Hz and for two alternative three-phase configurations, 220/380 V or 230/400 V, so the same hardware covers European-style grids and other regional ones. Its total harmonic distortion of 3 percent keeps the injected current within what network operators normally require.

### Where should the Deye SUN30-33-36KG04 be mounted?

The Deye SUN30-33-36KG04 is rated IP65 and declared for -25 to +60 degrees Celsius, so an outdoor wall is acceptable, though a shaded position keeps the enclosure away from the top of that range in summer. At 28.7 kg it takes two people, or a lifting aid, to place the unit on its bracket.
