HUAWEI solar inverter SUN2000-5KTL-M1-HC 5 kW three-phase, 2 MPPT

HUAWEI SUN2000-5KTL-M1-HC is a 5 kW three-phase solar inverter designed for residential and small commercial photovoltaic installations. The inverter converts DC power from PV arrays into AC power suitable for grid connection and three-phase distribution. With two independent MPPT inputs, the device can optimise energy harvest from separate PV strings and maintain stable output across varying irradiance and shading conditions. The unit supports monitoring and basic system integration functions to help manage production and ensure reliable operation.

Advantages

The inverter delivers balanced three-phase output for homes and small businesses, with two MPPT trackers to increase energy yield when arrays are installed on different orientations or with partial shading. It provides efficient DC-to-AC conversion and includes monitoring capability to track performance and fault conditions. Its compact design and built-in protection features support straightforward installation and long-term reliability in typical residential PV environments.

Suitable for

• Residential rooftop photovoltaic systems requiring three-phase output
• Small commercial PV installations up to approximately 5 kW
• Installations with two separate PV strings or different roof orientations
• Systems where monitoring and grid-tied operation are required

Key specifications

• Output power: 5 kW three-phase AC
• MPPT inputs: 2 independent maximum power point trackers
• Function: DC-to-AC conversion for grid-tied operation
• Application: residential and small commercial photovoltaic systems
• Mounting: wall or dedicated inverter mounting in protected outdoor or indoor locations (follow installation guide)
• Monitoring: built-in or supported monitoring functions for performance and fault reporting

How to use

Install the inverter according to local electrical codes and the manufacturer’s installation manual. Connect the PV array DC inputs to the two MPPT input circuits, ensuring correct polarity and adherence to string voltage and current limits. Connect the AC output to the building’s three-phase distribution or grid connection point through appropriate protection devices and breakers. Configure the inverter for the local grid parameters and enable monitoring features to record energy production and receive alerts. Regularly inspect DC and AC connections and follow safety procedures when performing maintenance.

Recommendations

Place the inverter in a ventilated, weather-protected location with ambient temperatures within the manufacturer’s specified range. Use correct cable sizes and protective devices to comply with grid interconnection requirements. For optimal energy yield, design PV strings so that each MPPT input sees similarly oriented modules with comparable shading conditions. Schedule periodic checks of electrical connections and firmware updates where applicable to maintain reliable operation.
