Go PowerTS-30 30 Amp Automatic Transfer Switch , Black

I purchased this to help control an inverter that I was installing in my travel trailer. The inverter and switch needed to go into the same compartment that housed the breaker/fuse panel and converter. The panel can be accessed (with difficulty) by removing 4 screws. I did not pay attention to the dimensions of the switch and this could have been a big mistake. The switch is not a solid-state device (as I had irrationally assumed) but an electrical contactor with some relays. Fortunately for me, I was able to wedge it into position and had just enough room for the install. The switch did not come with any instructions but there is a diagram inside the cover. The cover comes off fairly easy, but if you do not notice the instructions on how to remove it (moulded into the cover) you will really struggle like I did for a while. I hooked up the wiring as indicated, connecting the inverter to leads identified for a generator. This was a mistake. This switch (basically a normal seeking auto bus transfer switch) defaults to the generator connections. Fortunately, one of the reviews on Amazon gave the web site for a manual for the switch. I downloaded the PDF and it gave several wiring scenarios, including mine. I then went back into the enclosure and switched my shore power leads with my inverter leads. Now, when shore power is restored, the switch automatically returns to shore power as the source.Interestingly, If you are switching three sources, the manual shows using two switches together and how to hook them up to prioritize your sources.I also purchased a switch to remotely turn the inverter on and off (JR Products 12005 White Single SPST On-Off Switch with Bezel). I found it to be pretty easy to connect the switch in parallel with the inverter's power switch using control wire that I ran through a cooling vent in the inverter. Now if I am boondocking or loose campground power, all I have to do is open the breaker for the converter, AC and other loads that I do not want to power, then turn on my inverter. After a short time delay, the inverter comes on line and is powering my entire trailer, making it easy for me to pick and choose which 120v items I want to use.

We installed this along with 4 Walmart Deep Cycle 120 Amp Hour Batteries. (didn't need 4, but had them from other applications). Plugged the Sump Pump into the system.Put a BatteryMinder trickle charger on the system. When the street/shore power is on, the trickle charger is charging the batteries and running the sump pump.When the power goes out it switches the power to the 1200 inverter running from the battery array.We tested it a few times to make sure it would switch and switch back. Setup was a bit hairy so I suggest you have someone install it who knows home wiring. The diagram on Amazon of the wiring isn't correct. I had to phone the company and they sent me photos of the proper wiring for my application.Two weeks later we left on vacation. The ground was saturated with the recent rains. While driving to the east coast my daughter called and said the storms took out the neighbors trees which hit and broke the utility pole with the transformer in half. Lines laying out in the street, neighbors with flashlights wondering the streets looking for people with generators they could borrow to keep their basements from flooding. The generators that were available were too heavy to move easily. The power was out for 12 hours before linemen could get a new utility pole and transformer online.The system and transfer switch worked perfectly. I had my daughter monitor the setup and give us feedback while we were at the beach 900 miles away. Once the power came back online, the system took about 1 day to fully recharge.Had I not installed it, I would have had a flooded basement and well over $500 worth of damage, and dozens of hassles that the insurance probably wouldn't have covered (no flood insurance).Get one and have peace of mind while at work or on vacation.

It was recommended to us a ATS instead of a regular on/off switch. I searched for a good transfer switch and made the choice to go with Go Power. Very good product at a good cost, it was easy to install.

I bought a cheaper Automatic Power Transfer switch but it did not work well enough. That cheaper one has no problem switching from the secondary power source to the primary source but it had problem switching from primary to secondary. When switching from primary to secondary, there is a momentary loss of power so that some of my devices are turned off and on again. That is a problem for some devices that have a delay between the time your switch it on and when it is ready (e.g. a DVR). With this switch there is no momentary loss of power switching between primary and secondary power sources or back. The cheaper one I returned does have one advantage. It came prewired so that all I had to do was to plug things in. This one I had to do some wiring myself. Because there is no instruction included, I had to figure out where to put the wires by looking at the wiring diagram.There is a version of this switch that is prewired, but it costs about 3 times as much. To make my wiring look more professional, I stumbled upon something called strain relief, or bushing or cable glands (first time I heard of that term) right here on Amazon. Among the bushings or cable glands available is one that measures .875 inch, and it fits 3 of the knockouts perfectly. You can find it right herehttps://www.amazon.com/gp/product/B00MFSFAQE/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1With the bushings, I was able to run 3 wires into the 3 knockouts and make the job look "professional."

Very easy to install. I have a 2002 Dodge Ram camper van that had the factory deep cells and a 3 pole battery isolator under the hood. I disconnected it and changed my house battery to a 200 amp lithium. In doing this i needed to re-connect my distribution panel and shore power. The ATS is what was needed and everything is working as it should. I hard wired my 2000 watt inverter to the ATS using the yellow 12 gauge (looks like the orange) wire because 10/3 didn't fit the inverter connections. The other two connections in the ATS was wired with 10/3 wire because that is what is used for the shore power cable.I highly recommend this product.

Todos los materiales son de buena calidad y los contactos para juntar los cables son del tipo T que, para mi gusto, son los más fáciles de usar. La transferencia es casi instantánea cuando se va la luz de la fuente primaria (en mi caso la luz de la calle) para pasar la alimentación a la corriente de la fuente alterna (en mi caso un inversor conectado a un banco de baterías). A veces se pierde momentáneamente la señal de wifi de mi router pero esto sin afectar la señal del modem. Cuando regresa la luz de la calle hay un lapso de aprox 30 segundos antes que la alimentación regrese a la corriente de la calle, pero esto no implica que se pierde la luz durante 30 segundos, simplemente se sigue alimentando con la corriente del inversor y 30 segundos después se vuelve a transferir instantáneamente a la luz de la calle.Esta función es para permitir a un generador de volver a arrancar para las aplicaciones que los usan, como en los barcos, pero no afecta en nada la operación de sistemas que alternan entre la luz de la calle y cualquier fuente alterna.

Works, has multiple inputs (shore, generator, inverter, charge options) impressed on transfer time. Great product. Recommend if using in an off grid application.

Me gusto mucho el producto lo usa para relevar dos fuentes de energia lo recomiendo hace bien su travajo

Love the idea you can activate all ur plugs in the rv instead running all new wires everywhere from the inverter. Wish I saw this when I installed my inverter a few years ago. Now only thing I wish it came with was a breaker or a fuse when it hooks up to the rv inverter. It does not come with one. And not easy to get one. Go power could add this option as a addition for install. Like they offer a fuse / fuse holder for there inverters. Lucky I had old single 15amp breaker and breaker box laying around the garage. But other then that, great setup.
