Product Q&A

Q:What is the max output wire size?

It could run max 58A. You should use 4-6 AWG wire for the output. But we could only fit for 6 AWG wire now. We would update this unit in the next version and make it could 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. Then you would get a 48V combination and use 1 string in this box. 4 strings = 16 panels and it would work since the max current for 1 string would be 15A for this system. The cords and fuses are fitted.

Q:Where can I buy replacement 15A fuses?

We provide some as the replacements in our original package. It should be 4 more in the package. If you want to purchase more, you could view this link to help.

Q:Will this work with 12x400W panels connected in 3 series (4 total), pushing about 60A?

No. the fuse is 15A rated.

Q:What is the maximum current capacity for a single string?

The max current for 1 string is 15A for this system, as the fuses are 15A rated.
