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

Installed as per instructions. No issues. Works as it should

The media could not be loaded. 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.

works fine with generator and shore power but tripa righ away when inverter is used. This happens even when no gen or shore power connected.

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..

Despite re-tracing the PCB and replacing the SMD electronic elements the ATS looped and did not work. The first ATS bought from the so-called brand - Mastek works. The second issue ATS - DOESN'T WORK. See the pictures and the text above!!! I will think twice about buying this DECEPTIVELY compact and functional ATS...but poor quality. I feel cheated by the seller Mastek and by Amazon!!! Money back! I'm asking!? My wasted time waiting to receive a working product and the time for correspondence, WHO WILL PAY FOR ME!??? Will Mastek or Amazon pay the merchant!?

Works great in my Skoolie
