Description

KCGGD 380V 500V 100-2000KW High-quality three phase photovoltaic grid-connected metering cabinet

Introduction of photovoltaic grid-connected metering cabinet

Photovoltaic grid-connected metering cabinet.This product is mainly used in 100KW~2000KW high-power industrial and commercial photovoltaic grid-connected power generation systems.  and it is connected in series between the grid-connected inverter (or AC combiner box) and the power grid.

Power grid low voltage, power grid overvoltage, input lightning protection, system overcurrent, power grid isolation and a series of protection, multi-function meter display and fault status indication make the system operating status clear at a glance.

The product has passed the industry standard CCC certification, CE certification, ISO9001 quality management System certification, etc.

Product structure features:

The installation location of the meter and collector is reserved, the view window of the meter, the lead seal (anti-theft), the integrated design concept of the product.

The power distribution part and the metering part are completely isolated, the electromagnetic interference is reduced, and the photovoltaic special plastic case reclosing circuit breaker.

It can be equipped with on-line power quality monitoring, anti-islanding protection device, fault de-loading device, etc. Outdoor and indoor installations are optional, making installation more convenient. Support special requirements and function customization.

Environment condition:

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
