Go Power! TS-30 30 Amp Automatic Transfer Switch , Black

Easy to install, easy to use and priced well, use the wall mounted remote, it makes life easier.Make sure you use heavy gauge supply cable.I used this as an extra automatic switch in addition to the generator switch in my RV. This unit transfers power from my lithium battery bank to my RV when I boondock. It takes about 45 seconds to cycle and performs well.

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.

I replaced a manual transfer switch that I had in my shed that had Shore and Solar power connected. As the batteries ran out of power and the voltage dropped too low, the inverter would trip / the inverter alarm would go off and it would cut power from the shed. Not a huge deal as there's nothing essential in there, it was more my experimenting with solar, for lighting, the shed fan, and recharging of the mower battery. I just got tired of running outside switching back and forth from shore the solar setup that powers the two sealed 'car batteries'.This a automatic transfer switch did the job perfectly. I remember seeing these a few years ago when I first toyed with building a 'solar shed', but I don't remember why I didn't go with this over the EZ Generator Switch (https://www.amazon.com/gp/product/B00FADDE0A) - especially since this one is cheaper. Probably just because I didn't need to hard wire it and I could plug a cord directly into it from the inverter.One thing that I remember not liking was the 15 second delay in returning to the Primary power supply, but after re-reading / researching this topic, they've addressed that issue with the addition of some jumper pins coming off of the little circuit board that's at the bottom of the unit. I just found an old 'jumper cap' from an old computer (like this here: https://www.amazon.com/ZYAMY-2-54mm-Standard-Circuit-Connection/dp/B077957RN7) to bridge the pins and then tested. It would instantly failover to the secondary and instantly failback to the primary after that. Easy day. The updated instructions from their web site (https://s3-us-west-2.amazonaws.com/catsy.549/MOBI_MAN_GP-TS-30.pdf) show how to do it (see page 5).My setup is as follows:Solar Panels --> Charge Controller --> 2 Batteries --> 1000w Inverter --> Primary / 'Dominant' Supply on the TS-30 Automatic Transfer Switch.House Power --> Secondary / 'Default' Supply on the TS-30 Automatic Transfer SwitchFrom there the Load goes to a Two Circuit Panel ( https://www.amazon.com/gp/product/B00002N7MM ), that has a 15 amp circuit breaker that goes to the load.So far so good - now I just need to figure out why the GFI that's in the basement between the main panel and the garage trips during transfer. The shed gets it's 'shore power' from an exterior outlet that's connected to the garage and that GFI is part of the circuit.UPDATE:At first I thought it was due to load, but then realized that it would trip the GFI in the basement when changing from 'shore power' back to Solar... In both Solar and Shore mode, the outlets in the shed work fine. In further testing, it looks like the basement GFI only trips when going back to Solar, but ONLY if switching back and the inverter alarm was previously going off for something like a low voltage alarm while powering chargers overnight. When the sun comes back up and the batteries are back to 12+ volts, the alarm still stays on. Have an e-mail in to Renogy about this to try to get it all sorted out.

Easy to installPigtail ans Wago included for a fast installWiring diagram is clear

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.

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.

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

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