DC 500V / 1000V Solar PV Combiner Box 2 Strings Circuit Breaker For Solar Panel

Description

The solar DC string box is made of high-quality ABS and PC, so it is strong and durable. It can protect the amplifier from overload current, voltage damage, and short circuits, and can be manually powered off and reset to facilitate circuit inspection and maintenance. And the multiple protections allow for safe use. It is your ideal choice.

 

Key Features

Highly Functional: It can protect the amplifier from overload current or voltage damage while protecting the power supply to prevent short circuits from causing battery breakage and explosion. It can be manually powered off and reset, facilitating circuit inspection and maintenance.

 

High Safety: Multiple protections including surge protection, overload protection, lightning protection, as well as reliable DC components, can provide ensure the usage safety.

 

2 in 1 Out Design: This allows two inputs to be directly connected to one output, improving electricity utilization efficiency.

 

 

Real-time Detection&Remote Control: It can be directly connected to the monitoring system through external data lines, achieving real-time monitoring and remote control of the system's operating status.

 

Waterproof&Dustproof and Impact-resistant: It is well-sealed to be highly waterproof and dustproof (IP65). It also has a high impact resistance level (IK10), allowing it to be used in harsh environments.

 

Multiple Uses: Designed with reset lever, it is not only a DC circuit breaker but also an arc extinguishing switch to meet your various usage needs.

 

Selected Materials: Made of high-quality ABS and PC, it can resist wear, shock, and deformation, allowing it to be installed between the solar panel and the solar inverter.

 

Hassle-free Use: It uses MC solar connector for faster and safer installation. And you can use it directly after plugging it in.

 

Complete Kit: Complete accessories and an English manual in the package make this product convenient to use.

 

Guaranteed Customer Service: We aim to provide quality products and services. If you have problems, please feel free to contact us. We will reply and solve the problem for you as soon as possible.

 

Details

Practical Cover: The clear cover can well seal the product to achieve waterproof, moisture-proof, and dustproof while making it convenient to check the status of the circuit breaker at any time.

 

Round Corners: The round corners rather than sharp can prevent scratching your hands.

 

Application

It is mainly used for output protection of outdoor solar panels, motor homes, electric vehicles, UPS batteries, photovoltaic arrays, RV solar energy, and inverters, and is suitable for networked photovoltaic solar systems and off-grid solar power generation systems.
