📝 Product Description
The PV combiner box is suitable for grid-connected and off-grid power generation. The main function is to sink the input of PV cell array at one level, and to provide fast cut-off short-circuit fault protection and lightning protection to avoid damage to PV panels and inverters in case of failure.
It is also used to reduce the connection of photovoltaic arrays to the inverter, optimize the system structure, improve reliability and maintainability, and optimize power generation efficiency. The parallel mode has anti-backflow and anti-reverse access functions.
Our solution accommodates overcurrent protection devices, disconnectors, and surge protective devices (SPDs) in one solar combiner box. Depending on the application, combiners are equipped with monitoring devices to measure current, voltage, and temperature to ensure the availability of the strings and to maximize generation.
❓ Frequently Asked Questions
What is the main purpose of a PV Combiner Box?
