mankk 4 String PV Combiner Box IP65 Waterproof Solar Combiner Box with 63A Circuit Breaker Lightning Arreste Solar Connector and 15A Rated Current Fuse for On/Off Grid Solar Panel System PV-BOX-4X

Great Combiner box. Well built, works great. Couldn't be happier.

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.

I like these boxes makes hooking up solar panels fast and easy plus safe from lightning and power surges

Used it replace a defective combiner box. Solar was going in, but no solar comming out. Installed this unit and everything is now working perfectly. So far so good. Very pleased

The media could not be loaded. With some very minor alterations ....well best watch/listen to the video. Modified mounting and use of weather-tight.Photos of completed project.An afterthought....might add LEDs to outside of box to indicate power is being generated from EACH panel.UPDATE : Been in place for 2 years and still performing very well. NO signs of UV deterioration.

Nice workmanship and quality components for this 4 string solar combiner. The surge protector is a nice bonus!

Very well organized, compact, waterproof case. All components are well made, I especially liked the lightning arrester built in.

Really was looking forward to installing this unit on my solar system but….. I wanted to be sure of what I needed to do so I started looking for the owner’s manual. NADA! I called the 800 number and ask for and owners manual and sure enough she looked it up and said that the owners manual doesn't come with it. She sent me a link to request a manual on the sellers website.After reviewing the box it's pretty easy to figure out where the wires go
