JONASC AC110V 63A 2P Automatic Transfer Switch Solar ATS Generator Dual Power Changeover Switch 50Hz/60Hz

Excuse my messy wiring in the pic, it's not the final set-up. Now the instructions could be allot better but it's a great unit. Anyway, this unit performs precisely as intended. I initially had to return my initial purchase of this switcher because it was malfunctioning. It simply didn't function properly and emitted a loud noise. I assumed it was a defective unit and got a replacement, which works flawlessly. Here's my setup: I have my solar-powered battery pack as my primary power source, with the grid as a backup. I use it to supply power to my gazebo and everything within my backyard including all the lights, ceiling fans etc. My primary goal was to run the entire backyard entirely on solar power with a seamless transition to the grid when the battery is depleted. I've tested it multiple times, and the transition is truly smooth. The lights remain stable without any noticeable flickering or disruptions.

Bought this switch and installed it in a motor home so the input power would automatically switch from shore power to the inverter whether I unplugged to leave a campground or the power went out for any reason. Installation was simple, instructions were sufficient, and it functions flawlessly. Great switch a great price!

Have this running in my camper that has a large solar setup, and also the option to run off shore power. The instructions kind of sucked, but this is the way that I have it connected, and works great. The main trick is the lower lugs need to have jumper wires ran to both sides, and you can pull back out from either side on the bottom. The auto switch favors the left side power, and will automatically switch to the right side power if the left looses power, but if both have power at the same time, you will be getting your power from the left side of the switch. If you plan on running this on a Renogy inverter, you might want to look at the latest model, it seem to have shore power input on it.. I have the older model, so this auto switcher it the way to go for me.

Worked for about 2 years. Lose power often. Internal gears striped on transfer gear. On loss of normal power would not transfer when needed. Had to remove cover and do manual transfer.

Excellent product, very good and sturdy works like a charm. I recommend it.

Satisfactoria

Lo compré para mi batería lifpo4 y trabaja genial

I was happy to pay a little more for an American product, but when I received the switch, it has a short between line and neutral when switched to the "normal" source. Obviously, it was not tested. I'll buy a cheaper Chinese knockoff instead. I hope that most US companies do better than this. UPDATE: My mistake. The resistance between L and N of the normal source is 4K Ohms, which connection I assume is used to control the automatic switch. The switch was fine.

It's good ... working fine...change over time no power cuts...

Easy to install. Works perfectly. Recommend.

FACIL DE INSTALAR Y MUY BUEN PRECIO
