## Overview

Engineered for commercial and industrial solar installations, this Chinese-manufactured hybrid inverter delivers exceptional performance with its impressive 97.6% maximum efficiency rating. The unit operates across a wide MPPT voltage range of 160-650V and can handle up to 800V maximum DC input, making it suitable for large-scale photovoltaic systems requiring robust power conversion capabilities.

Dual MPPT channels provide enhanced flexibility for complex solar array configurations, with each channel supporting up to 72A of DC input current. The three-phase AC output supports both 220/380V and 230/400V configurations at 50/60Hz, ensuring compatibility with various grid standards. Built to withstand harsh environmental conditions, the inverter features IP65 protection and operates reliably across an extreme temperature range from -40°C to +60°C, while maintaining low harmonic distortion at just 3% THD.

## Frequently asked questions

### What sizes does the Deye SUN14/15/16/18/20K-SG05LP3 designation include?

The Deye SUN14/15/16/18/20K-SG05LP3 designation covers three-phase hybrid inverters from 14 kW up to 20 kW, so the rating installed depends on the variant ordered. A single shared set of figures is stored for this entry and describes the common hybrid platform, not the output of any one member of that 14 to 20 kW family.

### What supply does the Deye SUN14/15/16/18/20K-SG05LP3 need, and is it a hybrid unit?

The Deye SUN14/15/16/18/20K-SG05LP3 is recorded as a three-phase hybrid inverter for 220/380 V or 230/400 V grids at 50 or 60 Hz. Each pair is one four-wire configuration, phase voltage before line voltage, not two separate options. A three-phase service is therefore mandatory, and harmonic distortion is quoted at 3 percent.

### What is the MPPT operating window of the Deye SUN14/15/16/18/20K-SG05LP3?

The Deye SUN14/15/16/18/20K-SG05LP3 tracks between 160 V and 650 V and accepts a maximum DC input voltage of 800 V. Because the tracking window closes at 650 V while the absolute limit is 800 V, string design has to leave headroom for the voltage rise that occurs on a cold, bright morning before production properly begins.

### How much DC current can each MPPT of the Deye SUN14/15/16/18/20K-SG05LP3 take?

The Deye SUN14/15/16/18/20K-SG05LP3 has two MPPT channels, each rated for up to 72 A of DC input current. That is a very generous allowance for a string inverter and allows several strings to be paralleled on one tracker, which is what makes heavy DC oversizing practical on a hybrid system of this size.

### What are the efficiency ratings of the Deye SUN14/15/16/18/20K-SG05LP3?

The Deye SUN14/15/16/18/20K-SG05LP3 is rated at 97.6 percent maximum efficiency and 97.0 percent European efficiency. The weighted European value is the realistic one for annual modelling and implies about three percent of the array's DC energy is lost converting it, before any additional losses from battery charging and discharging.

### How demanding is the Deye SUN14/15/16/18/20K-SG05LP3 to mount?

At 51.9 kg the Deye SUN14/15/16/18/20K-SG05LP3 is a two-person lift and needs a solid wall with properly rated fixings; hybrid inverters carry the extra hardware that explains the mass. It is rated IP65 and specified from -40 to +60 degrees Celsius, so an outdoor location remains within its declared limits.
