Solar Combiner Box Install

Finally installing a combiner box on the older solar panels.

[@mericasilverpatriot9110]

Just hooked up a combiner box myself. Nice set up.

I was told that ‘tinning’ prevents the wire from corrosion. A solar installer told me that. Take that, with a grain of salt, I reckon!

[@kevincrawford2027]

I think tinning is a better choice than ferrules.

I just got one of these the other day. Found most of the connections needed to be screwed down more, most did half a turn, but the ones on the fuses for the solar leads were totally unscrewed. otherwise, it works fine.

[@kevincrawford2027]

Mine were all reasonably tight. Still got a partial turn on about half of them. I also installed another one but needed to put #4 wire in the output breaker. I had to move the breaker to a different location in the box so there was a straight shot to the breaker.

got the same problem with my cat..

[@Electronzap]

Nice.

[@vudunof]

Would a PV disconnect switch be required also, or would the breaker in the combiner box serve the same purpose?

[@kevincrawford2027]

I am not sure. You would need to check your local code. I do not have one but I have a second breaker next to my solar charge controller. My system is off grid.

Can you please tell me,Do them box's have blocking diodes

[@kevincrawford2027]

No they do not have blocking diodes.

That's funny.
