pure sine wave inverter

This 12V inverter with built-in transfer switch changes DC output from your RV batteries into AC power and sends it to the electrical system. Using pure sine wave technology, it creates clean power with low distortion, making it safe, efficient, and perfect for sensitive electronics like computers. The inverter can generate 2,650 starting watts and 1,500 running watts which is a great fit for appliances and electronics. Additionally, with the integrated transfer switch, it will automatically change from inverter to shore power when available.


Functions and Features

outlets and terminals on inverter

The inverter includes hardwired input and output terminals for AC loads, positive and negative DC input terminals that connect to your batteries, and a port for a fixed-mount remote (sold separately). It has a function switch that lets you select different output voltages (100V, 110V, 115V, and 120V) and frequencies (50Hz and 60Hz). This switch can also turn the power saver on and off. Additionally, the power saving adjustment dial near the function switch sets the input and wake up thresholds for the power saver.


The system includes a number of safety features. It offers protection from over/under voltage, overloading, and overcurrent. The inverter also uses a heat sink process to protect from extreme temperatures, and an internal cooling fan removes excess heat from the unit.


fuse block

For additional safety, installing a fuse between the battery bank and the inverter will protect your equipment from power surges. The Go Power 200-amp fuse block (sold separately) works with this unit and uses a slow blow time-delay feature to withstand surge current. This means it can handle short surges over 200 amps without blowing the fuse, which is great for devices with motors that require more energy to start.


Built-In Transfer Switch Automatically Switches to Shore Power

The integrated transfer switch selects the primary source of AC current. The switch inside of this inverter has been pre-wired to automatically change from inverter to shore power to conserve battery life. This switch includes a 20-amp leg rated at 120V. To prevent electrical interruptions, the time delay circuit board allows the alternate power source to stabilize before a transfer occurs. Additionally, since the switch only accepts one active source, it protects your electrical system from dangerous backfeed that can damage your equipment.


How It Installs

The inverter mounts inside your RV in a dry location with ventilation. It should be installed in close proximity to the battery bank, but not in the same compartment. The DC terminals are wired to the battery bank. There are several ways to connect the inverter to your RV's electrical system, but this will depend on your rig and how you want to use your inverter.


Available Fixed-Mount Remote Provide Easy Monitoring and Control

GP-SWR-A inverter remote

The Go Power GP-SWR-A Inverter Remote (sold separately) lets you turn your inverter on and off from inside your RV. It also has a LED which indicates the inverter's status.

Great price and very fast shipping. Best place for all your trailer needs

We are currently working on hooking up the inverter we ordered from etrailer for the maiden voyage in our new trailer. It appeared these items would not be arriving before we left, but after a quick phone call to etrailer and a conversation with Steve Z. in customer service our inverter was on it's way by 10:00 am that morning. It did indeed arrive in 2 days giving us time to hook this up. We were thrilled as we wanted to put this trailer to work off the grid. Great service. Thank you so much.

Delivery was right on time, I have yet to install.

One year + later, this inverter is great! I have it connected to two battleborn lithium batteries. We can run our TV although we don’t much, our Microware, or our coffee Kirin machine - of course not all at once. The fan is a bit noisy but it only fires up when drawing heavy from the inverter. Love it and recommend it.



by:

This product is reliable and works well to the stated 400 watts when the load is steady. I like that this unit works well with my 29.4V DC battery pack (7S). Past 250 watts, even small surges will trip the unit off. At around 250 watts(steady) my quart compressor cooler will kill AC power out when it kicks on. It appears that the 600 watt surge rating is inaccurate.



by:

I have this installed and the included remote does not work as described in the instructions. When not connected to shore power the remote shows the charger function on yet the instructions say this is not an option.

Also, I changed the power saver mode to 15 minutes from the default off. I didn’t see a change in the remote output after several hours.

Less than 10 days after I ordered this etrailer dropped the price $XXX.XX. That’s not insignificant and they wouldn’t do anything for me about it.



by:

I replaced my magnum that went out due to a wiring issue. It was easy to replace for the most part although the wire to the controll panel was 6 wire and the old one was 4. It works very well. All I lost was the self start of the old one. Very good product.



by:

Inverter failed around the one year mark with light use. 1 star for that but 3 stars overall because of GoPowers customer service who provided a replacement without trouble.



by:

After 4 days of use this inverter easily does anything I need it to do, which is largely charging batteries when taking road trips. It handled my Dremel and 3/8 drill, as well. Didn’t try the grinder ?.

It’s well made with an all metal chassis, including front and rear faces – the only plastic is the black cover. It is substantial and heavy enough that it doesn’t look and feel cheap or breakable.

Overall, I like the unit and would recommend it.

My only strike against it is, IMO, a design flaw at Go Power. It is nuts to have the power connections on the back so close together. One of them should be located where the ground connector is. If one uses something more substantial than the #6 wire Go Power recommends and one should if the inverter is more than about 3 or 4ft from the battery. I am using #6 CABLE for a 9ft run. The plastic caps make it difficult to impossible to use lugs made for more substantial cable, but the proximity of one to the other makes it a safety concern to remove the caps. I had to file one lug more narrow to make it fit inside the plastic and left the other uncovered.



by:

Product works designed. It was professionally installed along with instant hot water and 4 vmax tanks.



by:

etrailer always does great!



by:

I finally received my Go Power IC3000 after a nearly three-week delay. Unfortunately, I missed my window of opportunity to get it installed this year, so I am not able to complete a review of the product at this time. I can say, installation is going to be quite a challenge. The item is large and heavy. Finding a suitable location that meets all the requirements is going to be difficult. The batteries are located at the front of the trailer, while the AC lines are on the other side of the basement. Since the inverter cannot be located in the same area as the batteries, I'm not sure I am going to be able to reach everything and maintain the 10' maximum length requirement of the 0000 DC cable. We will see what happens next spring. I will post a follow-up review post-installation if possible.



by:

Everything went well. I’m very pleased with the service & Inverter.



by:

Works great, the unit is powering a work shed in the backyard. The Inverter is paired up with 400w of solar and two battleborn 100a batteries. The unit replaced a 3000w inverter from another company that fried twice within a year.



by:

Perfect to charge phones, computers, and other electronic items with off grid. And use my CPAP.



by:

This unit is well built and ready for 50 amp pass thru. Comes with built in 50amp circuit breakers and Romex clamps. Installed on our 2019 Grand Design Momentum and so far works great. Recommend the remote panel. Bob at GoPower was awesome with customer service and helped me set all parameters for lithium batteries. Sarah at etrailer was great and had shipped out an hour after I ordered to make my need date. I highly recommend GoPower and etrailer.



by:

The inverter works very well. The only reason I gave it 3 stars is because the front of the unit is made with cheap plastic. The screws that hold the electric outlet in the front of the unit is embedded into the plastic. The plastic broke the first time I plugged into the outlet. I was leaving in two days to go on a trip to Utah so did not send it back. I voided the warranty by opening the unit, reinforced the outlet by sandwiching the plastic front in between two pieces of aluminum and used screws to hold the outlet in place. Since doing this, everything has worked flawlessly.

I would not buy this item again due to the plastic front.

  • How Many AC Inputs Does Go Power Pure Sine Wave Inverter w/ Transfer Switch part # 34279458 Have
    The Go Power Industrial Pure Sine Wave Inverter w/ Transfer Switch part # 34279458 has one AC input and AC output. The reason the description says 2 AC inputs is because it is referring to the shore power and the inverter power as AC. However, I can see how that description can be misleading. This inverter takes 1 shore power AC input and your DC battery to provide AC power to the fuse panel. The transfer switch will draw power from shore power automatically when the RV is plugged in to...

    The Go Power Industrial Pure Sine Wave Inverter with Transfer Switch # 34279458 has a 1,500 watt capacity so you'll just need to look up how many watts your CPAP machine pulls to determine if the inverter is rated high enough to power it. You'll also want to check for the amp draw to determine if your battery bank will have enough to power it for the entire time. From what I can find a CPAP machine will typically pull about 30-60 watts without a heated humidifier or 70-100 watts with...

  • Version of Go Power Sine Wave Inverter that has Transfer Switch
    The terminals on the Go Power Heavy-Duty Modified Sine Wave Inverter # 34280178 are designed to have a 12 volt power source like a battery attached to and then on the other side of the inverter are standard sockets you'd see for AC power. This does not have a transfer switch like you mentioned that you'd run to a breaker panel/converter. For an inverter that does have a transfer switch we have the # 34279458 which might be what you are looking for to run to a breaker panel.

  • Compatibility of Atwood RV Gas and Electric Water Heater with 12V Battery
    The Atwood RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - 10 Gal Tank # AT94022 requires 120V for both the direct spark ignition and the heating element with thermostat.
