DC Combiner Box

DC combiner box is a key equipment in photovoltaic power generation systems, used to converge the DC output currents of multiple photovoltaic modules, simplify the connection with inverters, and improve the reliability and maintenance convenience of the system. It is usually installed between photovoltaic modules and inverters, with functions such as lightning protection, overcurrent protection, and monitoring.



Multi channel input and convergence

Supports multiple inputs of photovoltaic modules (such as 8, 12, 16, 24), with each current up to 11A and a maximum of 15A, meeting the needs of photovoltaic systems of different scales.

Multiple protection functions

Each input is equipped with a photovoltaic specific fuse to prevent current backflow in case of component failure. Equipped with DC high-voltage lightning arrester, both positive and negative poles have lightning protection function, and can withstand a maximum lightning current of 80kA. Anti reverse diodes prevent circulating current between strings.

Intelligent monitoring and communication

The intelligent combiner box has a built-in monitoring unit that can collect real-time data on each current, bus voltage, box temperature, lightning arrester status, and circuit breaker status, and transmit it remotely through the RS485 interface.

High protection level

The protection level reaches IP65, with waterproof, dustproof, rust proof, and salt spray resistant functions, suitable for harsh outdoor environments.
