YCX8-(Fe) Photovoltaic DC Combiner Box

Features

● The box can be made of hot-dip galvanized steel plate or cold-rolled steel plate to ensure that the components do not shake and remain unchanged in shape after installation and operation;
● Protection grade: IP65;
● Can simultaneously access up to 50 solar photovoltaic arrays, with a maximum output current of 800A;
● The positive and negative electrodes of each battery string are equipped with photovoltaic dedicated fuses;
● The current measurement adopts Hall sensor perforated measurement, and the measuring equipment is completely isolated from the electrical equipment;
● The output terminal is equipped with a photovoltaic DC high-voltage lightning protection module that can withstand a maximum lightning current of 40KA;
● The combiner box is equipped with a modular intelligent detection unit to detect the current, voltage, circuit breaker status, box temperature, etc. of each string of components;
● The overall power consumption of the modular combiner box intelligent detection unit is less than 4W, and the measurement accuracy is 0.5%;
● The modular combiner box intelligent detection unit adopts DC 1000V/1500V self power supply mode;
● It has multiple methods for remote data transmission, providing RS485 interface and wireless ZigBee interface;
● The power supply has functions such as simulated reverse connection, overcurrent, overvoltage protection, and anti-corrosion.
