Product Q&A

Q:What is the maximum output wire size?

It can run up to 58A. You should use 4-6 AWG wire for the output, but currently, it only fits 6 AWG wire. This will be updated in the next version to fit 4 AWG wires.

Q:Can this combiner box handle a 1600W system with 4s4p 100W 12V panels?

You should get 4 panels in 1 string to create a 48V combination and use 1 string in this box. With 4 strings (16 panels), it will work since the max current for 1 string is 15A for this system. The cords and fuses are fitted.

Q:Where can I buy replacement 15A fuses?

We provide some as replacements in the original package. There should be 4 more in the package. If you want to purchase more, you can view the provided link for help.

Q:Will this work with 12*400W panels connected in 3 series (4 total), pushing about 60A?

No. The fuse can be chosen as 10A, 15A, 20A, 30A, 40A, or 50A. A 60A output exceeds the standard fuse options for this specific configuration.

Q:What materials are used for the shell?

The shell is made of high-quality ABS or Polycarbonate (PC) plastic materials. The base and frame are ABS RAL 7035 grey, and the transparent window is PC tinted with UV protection.
