HLX Photovoltaic DC Combiner Box

The combiner box boasts an IP65 protection rating, providing waterproof, dustproof, rustproof, and salt spray resistance, making it ideal for outdoor installation. Utilizes PV-specific high-voltage surge protectors to safeguard the combined positive/negative busbars against ground faults. Continuous operating voltage (Uc) reaches DC1500V. The monitoring module employs reliable Honeywell Hall elements (DC CT sensors) to collect data on each string’s current, busbar voltage, and temperature. It provides alarm functions, local fault diagnosis, and monitors surge protector and circuit breaker status.

  • Fully Custom
  • Expedited Production Processing

Product Advantages:

1.Supports simultaneous connection of up to 32 PV strings.

2.Each string’s positive and negative poles are equipped with PV-specific fuses for fault protection. The fuse bases and fuses are matched to reduce long-term maintenance costs and ensure operator safety.

3.The monitoring module features a digital display showing real-time data per string (current, voltage), internal temperature, surge protector/circuit breaker status, system power, and device address. Includes RS485/MODBUS-RTU communication.

4.All external interfaces are equipped with surge protection.

5.Capable of receiving parameter downloads from local monitoring devices for analysis and processing.

6.The combiner box can be powered by external 220V AC/DC or its own internal power supply. If using the internal supply, no additional wiring is needed, simplifying installation.
