Xantrex 8080915 PROwatt SW Auto Transfer Switch

Trabaja muy bien

Great to switch between utility and solar power.

Had looked for this type of switch for a long time for use at our cabin in remote and deep woods in S Indiana about an hour from a major city. We are in a big valley on a small lake and do not have interior cell service with out our Wilson 70 db booster (a must have is the newer self adjusting unit that always maintains reception and not the older manually adjusted units). We had almost no OTA TV with out Winegard LNA-200 boosters on 2 antennas in attic and a Denny's stacker UHF/VHF antenna high above roof, and now have 21 stations and all major networks in perfect HD. Bought a used 15 device Verizon 7730L hotspot (using the little known Verizon no contract $65/mo UNLIMITED data only available on their PREPAID plan with auto pay) for internet, Netflix and Amazon TV (binge watch in high def w/the unlimited data plan) and to now run Amazon Cloud cams and Canary security cams. When power went out as it often outdoes with power cables running through the woods, these electronics all went down. You had to be there in person in the second floor utility closet to switch the Belkin 12-Outlet Power Strip Surge Protector with 10-Foot Cord that powers all the boosters including Wilson and a Netgear Nighthawk WIFI extender, from the AC plug to then plug into GpPower's 175-Watt Modified Sine Wave Inverter (no fan =low draw) and then clamp onto the deep cell trolling battery next to the inverter. Now with this badboy transfer switch installed, when the AC power goes off, it auto switches to the plugged in inverter connected to the deep cycle battery, and then automatically switches back to AC when restored. Ran long USB cords to some of the cameras off the same surge strip so they also function when AC power is out. Wilson booster draws 20W which is .17 amp which means that deep cycle trolling battery could run everything on the power/surge strip for a long, long time. Will prob run a long power cord to the hotspot which is near the Wilson interior panel downstairs. BE SURE that you order and correctly wire the 3 prong male adapter plug and female adapter plug for similar uses, as 2 wires from the transfer switch have no connectors. It comes with a marked 3 way male plug to plug into the inverter. Black wire is hot and is for the narrow flat plug, white wire is the return and is for the wider flat plug, and green is ground. I'll try do an update in a few months, but so far it's perfect for what we wanted. Now my wife and kids can make calls and use the internet from inside cabin if power is out, with out me trying to explain over the phone how to connect to and switch on the inverter in the storage closet by flashlight. That is priceless and calls for a beer.(Update 1/8/20)Still working great. When the power goes off, auto switches to deep cell batter on 175w inverter to power wifi security cameras. The jetpack mifi has its own large battery so we can still have the peace of mind with security during power outages.

This is a 15a transfer switch so if your load is higher than 15a this won't work for you. I installed the first one in a shed out back to protect a chest freezer there. I have shore power as the primary power and the inverter input is from two deep cycle batteries and a Xantrex sine wave inverter. The batteries are kept charged by solar panels and a solar charge controller. If power is lost this should be able to keep the freezer cold for a very long time. The transfer switch is easy to install. It comes with one 15a plug installed for grid power but the inverter supply and the output line is open wires. I bought two three prong plugs (male/female) and wired the plugs. You just have to make sure you connect the white and black wires to the correct terminals. I also want to say the transfer time is very fast. When I tested it I was watching an LED light and it didn't even blink during the transfer. Also it is NORMAL seeking power meaning when the grid power input has power the switch will go this source. For the second transfer switch I plan to connect to my refrigerator inside the house. The primary source I want to be a a solar generator that is kept charged by solar and the backup supply will be the grid power. If there isn't enough sun to keep the solar generator charged then the switch will transfer over to the grid to keep the refrigerator powered. This will save from 1.5 to 2 kWh/day in utility power cost. I recommend this transfer switch for projects that are less than 15 amps.

This is exactly the product I needed to complete an automatic battery backup for a sump pump. The box is high quality along with the cables. They even add labels to the cables so you know where they should be attached.I didn't take this thing apart, but all indicators is this is high quality. As soon as I plugged it in I heard the switch flip as it recognized the power was connected. When I unplug from the wall the switch drops and the sump pump draws from the inverter. It works flawlessly.While this isn't necessarily a cheap product, it is priced fairly. Good quality and I was able to save hundreds of dollars DIYing this project because of this switch.Minor criticisms:I would have liked the cables to be an inch longer. I would have liked to have male and female plugs included to complete the setup (green arrows in my attached pick show where I added those connectors).

This is the 2nd one of these Xantrx ATS's I've purchased, and both are being used the same way, which is technically opposite of their intended/labelled use. I have them wired so that the solar inverter is the main AC source, and the backup is connected to the utility/grid power. With this setup, if the solar inverter shuts down for any reason (low voltage, etc) it switches all the connected loads onto grid power, and switches back once the solar batteries are charged back up enough to power the inverter back on. The 1st unit I installed in 2020 and has been working flawlessly since, so I added the 2nd unit for our bedroom, which is powered by an Ecoflow Delta system, and 400W solar array. While the Delta does NOT automatically turn the AC inverter function back on once it's charging, this way we wont ever discover everything powered down becaise the battery got too low overnight, etc.

Switching cables appear to be made from good quality materials. Clearly Marked cables and easy to read instructions. Works flawlessly and not too bulky.

Have tested unit and it works as it should.
