## Overview

Designed for commercial and large residential solar installations, this high-performance smart PV inverter delivers exceptional power conversion capabilities. With its impressive 36.3kW maximum AC power output and industry-leading 98.7% maximum efficiency, it ensures optimal energy harvesting from solar arrays while minimizing power losses.

Built for durability and reliability, the three-phase inverter features robust IP66 protection rating, making it suitable for harsh outdoor environments. Each MPPT input can handle up to 42A of DC current, providing flexibility for various panel configurations. Despite its substantial 36.3kW power capacity, the unit maintains a relatively compact profile at just 19kg, facilitating easier installation and maintenance for solar professionals.

## Frequently asked questions

### What size project does the GoodWe SDT G4 15 33 suit?

The GoodWe SDT G4 15 33 is recorded with a single maximum AC power rating of 36300 W, or 36.3 kW, as a three-phase inverter, which places it in commercial rather than residential territory despite the '15 33' in its name possibly referring to a wider model family. At this scale, it suits a mid-sized commercial rooftop or small industrial site.

### How much DC current can the GoodWe SDT G4 15 33 handle per MPPT input?

The GoodWe SDT G4 15 33 accepts up to 42 A of maximum DC input current per MPPT channel. That current ceiling determines how many parallel strings, or how large a single string of high-output panels, can be safely combined onto one input without exceeding the inverter's rated tolerance, an important check before finalizing a string design.

### How efficient is the GoodWe SDT G4 15 33?

The GoodWe SDT G4 15 33 reaches 98.7 percent maximum efficiency, among the higher figures in GoodWe's commercial string range. As with most published inverter specs, this is a peak value rather than a seasonally weighted one, so actual annual conversion losses across varying load conditions will typically be a little higher than this headline figure implies.

### How heavy is the GoodWe SDT G4 15 33 for installation?

At 19 kg, the GoodWe SDT G4 15 33 is noticeably heavier than a small residential inverter, reflecting its 36300 W commercial power class, but it still stays light enough that most installers can manage it with careful lifting technique or basic mounting hardware, rather than requiring a crane or forklift used for larger utility-scale cabinets.

### What kind of inverter is the GoodWe SDT G4 15 33, and can it go outdoors?

GoodWe categorizes the SDT G4 15 33 as a Smart PV Inverter, and its enclosure carries an IP66 rating, meaning it is sealed against dust and can withstand powerful water jets from any direction. That protection level, combined with its three-phase 36300 W output, supports outdoor installation at a commercial site without extra weatherproof housing.
