PC for out door ,ABS for indoor long life PV junction cases, with PC enclosure for out door ,ABS ,plastic for indoor use PV junction boxes ,transparent smart solar combiner boxes 2 strings

Quick Detail:

In a large solar photovoltaic (PV) array, multiple solar modules are connected in series in a string to build the voltage up to proper levels for the inverter. Multiple strings of solar modules are then combined together in parallel to multiply the string output currents to higher levels for input into the inverter.

Description:

The combiner box is a device that combines the output of multiple strings of PV modules for connection to the inverter. It is typically used in the larger commercial and utility scale PV power plants (greater than 50kW). The combiner box commonly houses the input overcurrent protection fuse assemblies for several strings (from as few as 2 strings to as many as 32), as well as the combined bus of those inputs into a single main output.

Normally PV combiner box may also house several other components for the site, such as a DC disconnect, surge protective devices and string monitoring hardware.

Solar Combiner Box (PC/ABS/PLASTIC)

Specifications:

In a large photovoltaic (PV) grid generation system, it is generally to install a DC combining device between the PV module and inverter in order to reduce the connection between PV module and inverter, facilitate maintenance and improve reliability. Our intelligent photovoltaic combiner box with SPD series are especially designed to meet the requirement, which can provide a solution for PV power generation system matching with photovoltaic inverter. According to the input voltage of the inverter, a fixed number of similar PV modules can be connected to form a PV array by using PV array combiner box. Then different channels of PV arrays can be combined into the PV combiner box. Its output can be connected to inverter by way of circuit breakers with SPD protection.

To ensure body safety and reducing the danger. Longmax solar combiner has features as below:

1. Meet outdoor installation requirements, the degree of protection is IP54, has the function of avoiding UV, acid and alkali, moisture, mold and rat;
2. 12 strings of solar arrays can be input at the same time, each channel with 12A,1000Vdc (can be replaced to other level);
3. Each positive, negative string under the fuse protection;
4. With special high voltage PV SPD, both positive and negative pole have the function of thunder and lightning;
5. Use photovoltaic circuit breaker;
