Review: Works 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 desertcart 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. Review: Great Auto-Transfer Switch with instant failover, and instant failback (if configured to do so). - 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.desertcart.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.desertcart.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.desertcartaws.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 Switch From there the Load goes to a Two Circuit Panel ( https://www.desertcart.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. ## Features - Versatile Compatibility: Handles up to two 30-amp power sources simultaneously, providing flexibility in power management. - Easy Installation: Features knockouts that ensure a quick and professional installation process. - Delay Switch for Generators: Includes a delay switch to ensure safe and smooth power transitions when using a generator. - Built-in Protection: Safeguards connected devices by managing power transitions efficiently. - Compact and Efficient: Compact dimensions (9.65”L x 7.28”W x 4.75”H) for easy integration into RVs, boats, and off-grid systems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00153EYTO | | Batteries | 1 Unknown batteries required. | | Best Sellers Rank | #60,870 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #32 in Outdoor Generator Transfer Switches | | Brand | Go Power | | Bulb Type | LED | | Customer Reviews | 4.6 4.6 out of 5 stars (1,110) | | Date First Available | October 2, 2001 | | Item Weight | 1 pounds | | Item model number | TS-30 | | Lift Type | Automatic,Automatically | | Manufacturer | Go Power! | | Manufacturer Part Number | TS30 | | Mirror Lighting Type | Non-Illuminated | | Model | TS-30 | | OEM Part Number | TS-30 | | Product Dimensions | 9.65 x 7.28 x 4.75 inches | ## Images ![- TS-30 30 Amp Automatic Transfer Switch, Dual Source Compatibility - Image 1](https://m.media-amazon.com/images/I/810YIwRcIfL.jpg) ![- TS-30 30 Amp Automatic Transfer Switch, Dual Source Compatibility - Image 2](https://m.media-amazon.com/images/I/71qc0K4TOGL.jpg) ![- TS-30 30 Amp Automatic Transfer Switch, Dual Source Compatibility - Image 3](https://m.media-amazon.com/images/I/61X+r6a0TiL.jpg) ![- TS-30 30 Amp Automatic Transfer Switch, Dual Source Compatibility - Image 4](https://m.media-amazon.com/images/I/71f4K2xe7gL.jpg) ![- TS-30 30 Amp Automatic Transfer Switch, Dual Source Compatibility - Image 5](https://m.media-amazon.com/images/I/71jxcJ3c8KL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by R***T on May 2, 2014* I purchased this to help control an inverter that I was installing in my travel trailer.

Works flawlessly. *by I***N on May 18, 2025* I added this to my trailer when I expanded my solar system and added an inverter. It switches to and from shore power as it should. My default mode of camping is off grid so I inverted the signal leads and now it will wait for shore power or generator to get up and running for a few seconds before cutting over allowing for no interruption in power. Installation was so much easier thanks to the quick connectors inside. It really helps if you're working in a small space which made it worth the extra expense. ## Frequently Bought Together - Go Power!
