Photovoltaic Grid-tie Metering Switchgear

Photovoltaic Grid-tie Metering Switchgear. The product is mainly applied to 100KW~2000KW high-power industrial and commercial PV grid-connected power generation system, which can be connected in series between the grid-connected inverter (or AC convergence box) and the power grid.

Product Highlights
  • The installation position of metering meter and collector is reserved;
  • Metering meter can be viewed window, lead seal (anti-electricity theft);
  • Complete isolation of the power distribution part from the metering part, reducing electromagnetic interference;
  • PV-specific molded case reclosing circuit breaker and universal frame circuit breaker (optional), more reliable performance;
  • Optional online power quality monitoring device, anti-islanding protection device, fault resolution device, etc.;.
  • Optional outdoor and indoor installation, more convenient installation.
  • Support special requirements and function customization.

Overview

Photovoltaic Grid-tie Metering Switchgear. The product is mainly applied to 100KW~2000KW high-power industrial and commercial PV grid-connected power generation system, which can be connected in series between the grid-connected inverter (or AC convergence box) and the power grid.

The product has a series of protections such as anti-islanding protection, voltage closing, loss of voltage trip, grid low voltage, grid overvoltage, input lightning protection, system overcurrent, grid isolation, etc. The product can be connected in series between the grid-connected inverter (or AC converter box) and the grid.

Multi-function meter display and fault status indication make the system operation status clear at a glance, the product has passed the industry standard CCC certification, CE certification, IS09001 quality management system certification.
