Automatic Transfer Switch,Automatic Switching Between Utility Power、Generator and Inverter,Overcurrent Protection,Overvoltage and undervoltage Protection,63A

Easy to install works well seamlessly switches between land solar and generator power Have now purchased three of these units. They work flawlessly I would recommend them to anybody that upgrading the power system for the cabin on an RV. Is

Mount this in a Circuit Breaker Distribution Box (likely need an 8 DIN) and you have a pretty cool RV autocrossover with voltage readout. Very functional, and programmable. I mounted mine right over my breaker panel in my trailer conversion. Nice to have any sources plugged in all the time, inverter, generator, and city, and it tells me what is on and selects the best one. What more could you ask for. Many RV's overcomplicate this for hundreds, tons of weight and no data readout.

I installed this switcher in my trailer to switch between battery/solar, shore power, and a generator about a year ago and everything is working perfectly. I do wish there were screw mounting holes instead of the rail system though.

I like this little transfer switch.. I found the directions helpful . The quality is great and it is wonderful to have it automatically switch over to solar power and back again.. I like the solid connectors and the great customer service too..

it doesnt work.. period. no instructions but i found some online... but it literally doent do anything. Got a dude and i dont have the option to return for some reason.

This thing is fantastic. Levels above any other similar products that I could find on amazon.

It's exactly what I was looking for. I always wanted one that worked with 3 inputs and was simple and didn't look intimidating. All the extra features and displays just blew me out ofbthe water. I have been recommending it to other van lifers all over the internet and promoting the product. Love it. Just wish had better documentation (honstly it may have came with one but I might have not paid attention and lost it) I wish I knew how the switch connection on the bottomg right works.

I’m building a project and wanted a 3 way switch to auto transfer power. The one I got works great on grid and generator power but when it goes to inverter power no output. It say line in voltage and line out voltage but no actual power coming out. I tested it by switching the inverter power supply to the generator in and everything worked. But go back to inverter in and nothing out.
