Detail

PRODUCT OVERVIEW

This product is mainly used in photovoltaic distributed grid-connected power generation system, which

is connected in series between 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 CCC

certification, 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.

Grid-connected switch
Self resetting overvoltage and undervoltage protector1. When the power grid is cut off or the bias voltage is greater than 20%, it will automatically disconnect (internal disconnection);
2. When the power grid returns to normal, it will automatically close (internal connection);
Special photovoltaic reclosing circuit breaker1. When the power grid is cut off or the bias voltage is greater than 20%, it will automatic break-brake (operation handle action);
2. When the power grid returns to normal, it will automatically switch on (operating the handle);
3. Manual operation and automatic operation can be switched;
Changshu molded case reclosing1. When the power grid is cut off or the bias voltage is greater than 20%, it will automatically trip (the delay tripping time is adjustable from 0 to 0~10S);
2. When the power grid returns to normal, automatic switching;
3. Manual operation and automatic operation can be switched;
