Product Description

Microinverter Test System

Introduction:

All microinverters operate in parallel and directly convert the DC electricity from each photovoltaic module into AC electricity for grid connection. During operation, microinverters only have a few dozen volts of DC voltage, significantly reducing safety hazards. They improve overall efficiency in cases of shading or performance differences among modules, minimize safety risks, and have the advantages of being compact, lightweight, and easy to install and use.

Features:

1. No need for personnel to select voltage levels, avoiding accidental operations that may lead to safety incidents.
CAN communication automatically determines power without the need for manual intervention.
PLC human-machine interaction display is intuitive and clear.
