Product Overview
The HLX-PV photovoltaic combiner box is suitable for inverters with a maximum input voltage of DC550V/DC1500V. The box can be made of stainless steel or cold-rolled steel and has passed tests for fire resistance, temperature rise, impact resistance, and UV resistance, reaching an IP65 protection level. This product is designed and configured in strict accordance with the "Technical Specifications for Photovoltaic Combiner Equipment" CGC/GF 037:2014, providing users with a safe, simple, and aesthetically pleasing photovoltaic system product. The HLX-PV24/Z/D lightning protection combiner box combines the DC input of up to 24 photovoltaic array strings into one or more output lines. Each line is equipped with a fuse, and the output is equipped with a surge protector and circuit breaker, greatly simplifying the DC switchgear and inverter input wiring. It provides surge protection, short-circuit protection, and grounding protection. Combiner boxes are available in intelligent and non-intelligent types. The intelligent lightning protection combiner box has a built-in combiner monitoring unit that can monitor the current input of each photovoltaic string, the total output voltage, the temperature inside the box, and the status of the surge protector and circuit breaker.
The internal layout of the device is clear and concise, with neat and reasonable wiring. It boasts high reliability and simple maintenance. With outdoor wall-mounted installation, it can adapt to various harsh environments.
Except for the core components, other parts can be customized according to user requirements.
