Menič HUAWEI SUN2000-20K-MB0 20000 W trojfázový menič

HUAWEI SUN2000-20K-MB0 is a three-phase solar inverter with a nominal AC output of 20,000 W designed for grid-connected photovoltaic systems. It converts DC power from PV arrays into usable AC power for commercial or large residential installations and supports monitoring and protection functions. The unit is intended for rooftop and ground-mounted arrays and is compatible with standard three-phase distribution systems.

Advantages

The inverter provides high conversion efficiency and stable three-phase output suitable for medium-to-large PV systems. Integrated monitoring capabilities allow for real-time performance tracking and fault reporting. Built-in protection functions help ensure safety and compliance with grid requirements. Compact design and thermal management features support reliable operation in a range of installation environments.

Suitable for

• Commercial rooftop photovoltaic systems
• Large residential three-phase installations
• Ground-mounted PV farms of small to medium size
• Sites requiring grid-compliant three-phase inverters with monitoring

Key specifications

• Nominal AC output power: 20,000 W
• Phase type: Three-phase output
• Application: Grid-connected photovoltaic systems
• Supports real-time system monitoring and fault diagnostics
• Protection features: anti-islanding, over/under voltage protection, and thermal protection
• Suitable for rooftop and ground-mounted array installations

How to use

Install the inverter following applicable electrical codes and manufacturer installation guides. Mount the unit in a ventilated, weather-protected location with adequate clearance for cooling and service access. Connect DC inputs from PV strings with appropriately sized DC cabling and overcurrent protection, and connect the AC output to the site's three-phase distribution board using qualified electrical workmanship. Configure monitoring and protection settings through the inverter's interface or management platform and verify grid-connection parameters before commissioning.

Recommendations

To maintain performance and safety, schedule periodic visual inspections, keep ventilation paths clear of dust and debris, and ensure firmware and monitoring software are kept up to date. For system design, match string configurations and maximum input voltage to the inverter's input range and include proper surge protection and external isolation where required by local regulations.
