Product Description
PV String DC Combiner Boxes are key components in the PV Solar power systems, which are placed between Solar Modules and the Inverters.
Simplify the physical wiring between solar panel and inverter Fault current protection for each PV String Fault alarm Easy installation and maintenance.
1. With DC FUSE
2. With DC Surge Protection Device
3. With DC circuit breaker or DC load isolation switch.
Strong adaptability
1. IP65 design,waterproof,anti dust and anti ultraviolet.
2. Strict test for high and low temperature,used widely/
3. The simple installation, the simplified system wiring, the convenient wiring.
4. The box body is made of cold rolled steel and other metal materials.
Flexible configuration
5. Used for single crystal silicon solar modules, poly crystalline silicon solar modules, thin film solar modules. Current rating
of the photostatic fuse, circuit breaker, load isolation switch is modified.
Feature
structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter.
2. Except the PV junction function, the pc combiner box should also have reverse current prevention, over-current protection,over-voltage protection, lightning protection etc a series of perfect protection functions, meanwhile, checking the running state, current, voltage and power after junction, arrester state, collection of DC circuit breaker state and Arc detection,leakage,detection(optional) and so on.
3. The PV combiner box we manufacture is equipped with all the functions mentioned above, configuration with on grid/off grid solar inverter to make up a complete set of solar power system.
4. When choose the pv combiner box, based on the input dc voltage range and output power of inverter, certain qty of panels will be connected in series as a string, certain strings in parallel will connect to the PV combiner box for junction, via control of circuit breaker and protection of arrester, then feed to the inverter.
