Product information

Description

Doktorvolt PV DC Combiner Box DV-4432-FOT is a two-string solar/DC distribution unit designed for photovoltaic arrays. Rated for up to 1000 V DC, this combiner box consolidates two PV strings into a single DC output and integrates Type 2 surge protection with a PG cable gland interface for secure cable entry. The compact enclosure is suitable for rooftop and ground-mounted installations where centralized DC connection, overcurrent protection and surge mitigation are required.

Advantages

The combiner box provides centralized connection of two photovoltaic strings, reducing wiring complexity and improving system organization. Built-in Type 2 surge protection limits transient overvoltages at the PV array side, helping to protect downstream inverters and equipment. The PG cable gland interface ensures sealed and strain-relieved cable entries, while the 1000 V DC rating supports common commercial and residential string voltages. The unit is designed for straightforward installation and maintenance in outdoor solar environments.

Suitable for

  • Small commercial and residential rooftop solar arrays
  • Ground-mounted PV installations with two-string sub-arrays
  • Remote or distributed inverter setups requiring local surge protection
  • Systems where tidy DC consolidation and secure cable entry are needed

Key specifications

  • Number of PV input strings: 2
  • Maximum DC voltage rating: 1000 V DC
  • Surge protection level: Type 2 (T2)
  • Cable entry: PG cable gland interface for sealed connections
  • Function: String consolidation with surge protection and single DC output

How to use

Mount the combiner box at the PV array or near the inverter following local electrical codes and site safety requirements. Route each string positive and negative conductors through the PG cable glands and terminate them on the corresponding input terminals. Verify polarity and tighten terminations to the specified torque values. Connect the consolidated DC output to the inverter or downstream DC distribution. If the unit contains replaceable surge modules, check their status indicators periodically and replace modules according to the manufacturer instructions and after significant surge events.

Usage recommendations

Install the combiner box on a non-combustible surface with adequate clearance for ventilation and service access. Use appropriately rated conductors and overcurrent protection devices sized to the string currents and system voltage. Perform periodic inspections of cable glands and surge protection components, and follow local regulations and inverter manufacturer guidance when integrating the combiner box into the PV system.
