Gada 16 String Input 1 Output 1000V IP65 Solar PV DC Combiner Box

Product Description

 

Product Description

The PV DC combiner box is designed to combine multiple photovoltaic strings into a single DC output, providing centralized connection, protection and distribution for solar PV systems.

This 16-input, 1-output combiner box allows up to 16 PV strings with the same electrical specifications to be connected in parallel. The combined DC power is then transmitted to the solar inverter or DC distribution equipment.

Equipped with DC fuses, a surge protective device and a DC circuit breaker or isolating switch, the combiner box provides protection against overcurrent, short circuits and transient overvoltage. It also allows the DC circuit to be safely isolated during system inspection and maintenance.

The enclosure is designed for outdoor photovoltaic applications and helps simplify system wiring, improve installation efficiency and reduce the affected circuit range during maintenance or system faults.

Product Features

1. Integrated DC Protection

2. 16-Input and 1-Output Configuration

Supports the parallel connection of up to 16 photovoltaic strings and combines them into one centralized DC output.

3. IP65 Protection Degree

The enclosure provides protection against dust and water ingress, making it suitable for indoor and outdoor photovoltaic installations.

4. Reliable Metal Enclosure

The box body is manufactured from cold-rolled steel, providing good mechanical strength and protection for the internal electrical components.

5. Simplified System Wiring

The centralized input and output design helps reduce field wiring, improve installation efficiency and simplify system inspection and maintenance.

6. Wide PV Module Compatibility

Suitable for monocrystalline silicon, polycrystalline silicon and thin-film photovoltaic modules.

7. Flexible Component Configuration

The ratings of the DC fuses, circuit breaker and isolating switch can be configured according to the voltage, current and protection requirements of the photovoltaic system.

8. Convenient Maintenance and Isolation

The output circuit can be disconnected during inspection or maintenance, helping reduce the affected area in the event of a system fault.
