IP66 Solar Combiner Box， 32A PV DC Isolator Switch with Solar Connector for Solar Panel Solar Power System RV, Boats, and Off/On-Grid Solar System

A bit on the spendy side, but it was complete and robustly built. No extra trips made for an enjoyable install.

I thought that I already wrote a review for this thing, but here goes. It looks like this allows you to switch on/off one solar circuit. That is correct. But it actually loops back that same circuit internally, so it actually switches it twice. Technically, this thing is four switches. Four physically separated circuit-interruption devices inside a box with one lever that opens/closes all four of those together. It comes, by default, with two of those four used for the + of your solar loop, and the other two of those four used for the - of your solar loop. You can change it around a little, if you're brave and know what you're doing. I use this to turn on/off two different solar loops. One little note: The one I got broke the plastic handle almost immediately, and Amazon replaced it for me. The torque needed to turn the handle is fairly high, and the handle is plastic, but I was still surprised that it broke. The replacement worked fine with no problems so far, so I'm guessing that the first one just had a manufacturing defect. I'm using this for 880w of solar on an RV. Great to have this for a safety shut-off.

No issues at all

At first I thought this was a good product. Purchased in January of this year it’s coming up on one year old. However I had to take it out of use months ago because it was filling with water!! The box was protected from the elements but it didn’t matter. I’m lucky I caught this issue before a short occurred! I threw it in my junk pile and ordered a different one. Today I decided to take it apart and what do I find?! It’s still moist with droplets after being in a house for a long time!!! It smells like wet carpet. You can see the moisture in the pictures and the poor wiring job too. Don’t ever label something water “proof” unless you are darn sure. I would recommend you stay away from this dangerous device that is supposed to be a safety device. Buy an IMO branded disconnect. Top quality like nothing I’ve seen. Worth the extra money. Make sure you are doing your monthly or weekly or whatever scheduled maintenance on your equipment to stay safe and catch potential disasters like this one could have been had it continued to collect water. Zero stars!!

The switch was a little bigger than I expected but is well made and has a solid feeling when operated. Recommended.

This is an awesome switch box, very sturdy. So far it is working perfectly.

I liked this a lot better then the aims 4 wire disconnect. So I bought 2. More money but better unit

Four stars for now because it seems to be a solid product that will work well with my solar panels. Knocked off a couple of stars because the one I received was clearly USED -- and the box was beat up as well. This is absolutely intolerable -- back it went for an exchange.
