Off Grid Combiner Box
DC combiner boxes link PV inverters and PV arrays, combining the output of a large number of strings to improve PV performance.
Through the design of our combiner box, we enable easy integration of additional functions, such as the inclusion of switches and a second MPPT.

With over 10 production lines, we produce over 200w annually and receive out orders at any volume.
We also carry out quality testing that determines the durability of our combiner boxes under extreme conditions.
