Perfect for off grid solar set ups

Item has fast delivered. I recommended this.Thanks Amazon.

I bought this for the solar setup on my RV, 4-2 panel arrays. Using 2 panels for each array allowed me to use 10 Ga solar extension cables and they plug directly into the bottom of this combiner box. No cable ends to put on and minimal screw connections. Each cable set runs through a fuse and then through a breaker after combined. Adding the cables between the combiner and the solar charge controller was very easy. There is enough room to manipulate the cables in the box and the connection points are easy to access and secure. There were no extras to buy and no modifications needed. All the components seem to be good quality and all the connection points and exit glands are properly sized for the required cabling.I used a heavy magnet at each corner to mount this box to the back of my external tv box, in my rig that is right behind the wardrobe drawers with good ventilaton and easy access.If you are looking for a simple plug and play solution this is a huge safety upgrade over simple Y type combiners this is a good option. The fusing is not required by code in all applications but it is always a good idea.I would highly recommend this box for anyone wanting to combine 4 or less solar arrays safely and simply.

decent quality would buy again
