3-phase solar inverter HUAWEI FusionSolar 10 kW with 2 MPPT inputs

HUAWEI FusionSolar 10 kW is a three-phase solar inverter designed for residential and light-commercial photovoltaic systems. It converts direct current (DC) produced by solar panels into alternating current (AC) suitable for three-phase grid supply. The inverter features two independent MPPT inputs for separate string tracking, allowing optimized power harvest from arrays with different orientations or shading conditions. Built to fit centralized three-phase installations, it supports multi-string configurations and aims to improve overall system efficiency.

Advantages

The two MPPT inputs enable independent maximum power point tracking for different strings, reducing mismatch losses and improving yield in mixed-orientation roofs or partially shaded installations. As a three-phase unit rated at 10 kW, it provides stable power distribution across phases for balanced loads and grid compliance. The design emphasizes reliable DC-to-AC conversion with compatibility for multi-string PV arrays, making it suitable where centralized inverter performance is required.

Suitable for

• Residential three-phase homes with medium to large PV arrays
• Light-commercial roofs and small business installations
• Systems with panels on multiple roof aspects or varying tilt angles
• Installations where partial shading affects different strings
• Centralized inverter setups requiring robust three-phase output

Key specifications

• Output power rating: 10 kW three-phase AC
• Number of MPPT inputs: 2 independent MPPT channels
• Input type: DC input from multiple PV strings
• Application: Residential and light-commercial PV systems
• Configuration support: Multi-string and centralized three-phase installations

How to use

Install the inverter according to local electrical codes and manufacturer installation guidelines, placing it in a well-ventilated, frost-free location with adequate clearance for wiring and cooling. Connect PV strings to the two MPPT inputs, keeping strings with similar orientation and tilt on the same MPPT where possible to maximize tracking effectiveness. Wire the AC output to the three-phase distribution panel or grid connection point using appropriately rated cables and protective devices. Commission the inverter following start-up procedures to configure grid parameters and monitor initial performance.

Usage recommendations

For optimal energy yield, group panels with similar orientation and shading characteristics per MPPT input, ensure proper DC string sizing within the inverter’s voltage and current limits, and perform routine visual inspections and monitoring to detect any underperformance or wiring issues.
