What is a DC combiner box?
Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.
What are the different types of PV combiner box?
VRM offers different types of Solar PV Combiner Boxes based on customer requirement. They deal in Array Junction Boxes, string Combiner Boxes, and string Combiner Boxes. The Solar PV Combiner Box is customized based on the input leads from the Solar PV Module and the output lead either to an inverter or a Main Junction Box (MJB).
How are PV DC combiner boxes tested?
PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.
How many strings does a PV combiner box have?
As with many other solar devices, PV combiner boxes have varying capacities. The capacity of a PV combiner box is typified by the input voltage, output voltage, and total DC output. The higher the capacity of combiner boxes, the more power they can handle. Generally, a combiner box can have at least 3 strings and as many as 52 strings.
