Solar Grid Connected Metering Low Voltage Cabinet

●Material:cold rolled plate/Stainless steel
●Protection grades:IP55
●Installation mode:Vertical
●Support special requirements and function customization


This product is mainly used in photovoltaic distributed grid-connected power generation system, which is connected in seriesbetween grid-connected inverter and grid. The product has a series of protections such as grid low voltage, grid overvoltage, input lightning protection, system overcurrent, grid isolation, etc. Accurate electric energy metering, transmission and intelligent operation control are essential parts of household grid-connected power generation system. The product has passed CCCcertification, CE certification, ISO9001 quality management system certification, etc.

Main Characteristics:

Reserve the installation position of metering meter and collector;

Visual window and lead seal of metering meter (anti-electricity stealing);

The integrated design concept of the product, the power distribution part is completely isolated from the metering part, and the electromagnetic interference is reduced;

Special photovoltaic molded case reclosing circuit breaker, with more reliable performance;

It can be matched with on-line power quality monitoring and islanding protection device, fault

disconnection device, etc;

Optional outdoor and indoor installation, making installation more convenient;

Support special requirements and function customization.
