Just received the 6 string combiner box. Great quality and plenty of space. The box, with the proper hardware, has space for 10 strings. The ground for the panels have ferrules, the rest don't. ( there are pros and cons to using ferrules on positive leads.) The fuse holders read 32A. However, the fuses are 15A. Lately I have been buying VEVOR products and have found no problems with them, including the pure sine wave inverters.
