Function

The SUN2000 is a three-phase grid-tied PV string inverter that converts the DC power generated by PV strings into AC power and feeds the power into the power grid.

Model

This document involves the following product models:

• SUN2000-196KTL-H0
• SUN2000-200KTL-H2
• SUN2000-215KTL-H0

Figure 2-1 Model (SUN2000-196KTL-H0 is used as an example)

• The SUN2000-196KTL-H0 is applicable only to the Chinese mainland. For other countries or regions, Huawei does not provide quality assurance.
• The SUN2000-196KTL-H0, SUN2000-200KTL-H2, and SUN2000-215KTL-H0 inverters described in this document must not be connected to a winding (of the transformer station) that has other models of inverters connected to it.

Networking Application

The SUN2000 applies to grid-tied PV systems for commercial rooftop projects and utility-scale plants. Typically, a grid-tied PV system consists of the PV string, SUN2000, AC power distribution unit, and step-up transformer.

The SUN2000 is powered by a dedicated power transformer instead of connecting to low-voltage overhead power lines.

Supported Earthing Systems

The SUN2000 supports the IT earthing system.

Figure 2-3 Earthing system

The SUN2000 supports the IT earthing system in PV-only scenarios. The use of the SUN2000 in other types of earthing systems, such as TT, TN-C, and TN-C-S, is not recommended. (If such an earthing system is encountered, contact the Company's engineers.)
