Product Description

The HUAWEI SUN2000-5KTL-M1 is a high-performance three-phase solar inverter designed to efficiently convert the direct current (DC) power generated by photovoltaic (PV) solar panels into three-phase alternating current (AC) electricity suitable for use in homes, commercial buildings, and industrial installations. It’s part of Huawei’s SUN2000 series of smart string inverters, known for combining advanced power conversion, smart safety features, and intelligent energy management in a compact and durable design.

With a rated output of 5 kW and a maximum AC output of approximately 5.5 kW, this inverter is well-suited for medium-sized solar arrays. Its high conversion efficiency of up to 98.4 % ensures that more of the energy captured by your solar panels is turned into usable electricity, maximizing your overall system yield and lowering your energy costs.

The SUN2000-5KTL-M1 features two independent Maximum Power Point Tracking (MPPT) inputs, which help optimize energy harvesting even when panels are installed in different orientations or experience partial shading. This improves system performance and flexibility in layout and installation.

Safety and reliability are central to its design. The inverter includes AI-based arc fault circuit interruption (AFCI) technology, which detects and mitigates dangerous arc faults to reduce fire risk, as well as surge protection, anti-islanding protection, reverse polarity protection, and residual current monitoring to safeguard both equipment and property. Its durable IP65-rated enclosure enables outdoor installation and protection against dust and water ingress.

The unit supports smart connectivity and monitoring, allowing installers and system owners to track performance via integrated Wi-Fi, RS485, Ethernet, or optional 4G communication modules. This makes remote monitoring, configuration, and troubleshooting easy through Huawei’s FusionSolar platform or compatible apps.

In addition, the inverter is battery-ready with a built-in interface that supports integration with Huawei’s LUNA2000 series energy storage systems, enabling future expansion into hybrid system setups that store solar energy for use during grid outages or peak pricing periods.

Compact and relatively lightweight (about 17 kg), the Sun2000-5KTL-M1 is easy to install and service. It operates quietly using natural convection cooling and handles a wide range of environmental conditions, with an operating temperature range from approximately –25 °C to +60 °C.

Overall, the HUAWEI SUN2000-5KTL-M1 5.5 kW 3-Phase Inverter is a versatile, efficient, and robust solution for grid-tied solar systems, offering strong performance, advanced safety, and smart features that make it a reliable backbone for modern solar energy installations.
