pure sine wave inverter

This 12V inverter changes DC output from your RV batteries into AC power so you can plug in tools and appliances. Using pure sine wave technology, it creates clean power with low distortion, making it safe, efficient, and perfect for sensitive electronics like computers. Plus, the inverter can generate 1,750 starting watts and 1,000 running watts which is a great fit for appliances and electronics.

Functions and Features

outlets and terminals on inverter

The inverter includes 2 GFCI outlets 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 110-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 110 amps without blowing the fuse, which is great for devices with motors that require more energy to start.

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.

Available Fixed-Mount Remotes Provide Easy Monitoring and Control

There are 2 fixed-mount remotes (sold separately) that let you monitor and control the inverter from inside your RV.

GP-SWR-A inverter remote

For a simple, no-frills option, the Go Power GP-SWR-A Inverter Remote lets you turn your inverter on and off from inside your RV. It also has a LED which indicates the inverter's status.

GP-ISW-R-12 inverter remote

For additional features, the Go Power GP-ISW-R-12 Inverter Remote provides LED indicators that display the voltage, output power, inverter status, power saving mode status, and fault conditions. It also has a power button that controls the inverter.

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


Used this 3 time in 2 weeks (received and installed it on March 4, 2022) and it has already broken. Inserted in a plug with three prongs and the plastic cracked and pushed the outlet in. If I remove the plug I don't think I will be able to plug it back in. The outlet is no longer mounted to the case and moves in and out freely. For the price I paid for this inverter, I am not happy about the build quality. Glad I am testing this out before going out on the road trip. This review is for the Go Power 1000w 12v Industrial Pure Sine Wave Inverter. I have contacted the manufacturer and will update this review if etrailer allows editing reviews.

We hate to see the product not live up to its quality. I have sent this information over to our customer service team for them to contact you.


arrived timely ,however the packaging was destroyed, luckily item was undamaged and worked perfectly, which was surprising due to the damage of the packaging. a little more attention to packaging would make it perfect.


Have only used for 10 hrs. It is functioning properly at this time.


Perfect fit.






This was a like for like replacement for 1500watt Go Power in my Lance camper, so installation was easy and it was delivered the day after I ordered it. I was surprised it arrived so quickly. I will certainly keep that in mind if I get stranded at a campground.


This inverter was exactly what the customer needed for their small RV solar setup. After a few adjustments to power flow and charge setup, it works wonderfully. From a tech point of view, I like the flow-through 50A service and ease of installation.


We had an unexpected failure of a well known inverter product. We were in desperate need as we were moving permanently out of state. This product was just what we needed to keep our fridge powered while on the road during our move. We appreciate the hard work and dedication to get this new product to us before we moved. Kristin did an amazing job to get us going without any hitches. Thank you!


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.


Good advice to help decide which inverter is right for us. Really fast shipping and delivery.


I originally hooked the inverter charger up to deep cycle marine lead acid (wet cell) batteries but have since upgraded to lithium batteries. What a difference in performance. I highly recommend LiTime batteries. They are 1/2 the weight and perform lead acid batteries in every way. The settings on the inverter charger needed to be changed by am very happy with it. The charger failed in just less than a year but they replaced the failed unit promptly after providing the pertinent information. Great service! Love it. It allows us with the lithium batteries to Boondock with the convenience of 120 volt appliances!


I am always amazed at how well the team and eTrailer service customers. The communication from product purchase to delivery is exceptional. Price/value of products is highly appreciated as well. I always save time and money when going to eTrailer to find parts for my Lance 2445 Trailer.


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.


When I installed the inverter to my camper I was unaware that the entire camper would be run through this inverter protected wit 20a breaker which would not handle the load when air conditioner was used. I have since isolated the inverter and installed a subpanel to handle the just the refrigerator and gfci outlets. We will be primitive camping next week and I can update this rating then.


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.


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.


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.


Quick shipping, easy install, works gre at.


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.


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.


Installed last year in a horse trailer with living quarters. Using with a pair of Dakota lithium batteries. Works great. Powers Microwave with ease. love the ability to pull from battery while also using generator; i can run both microwave and coffee maker together like this.

Points of note:
1) When inverter is turned on there is a quiet weird chirp occasionally. If you're a light sleeper sensitive to sounds, be prepared for a "what is that?" if it is installed in the LQ area.
2) If batteries are full and i plug in my Furman generator (Costco purchased from Costco), the generator gets tripped in to overload when float charging is enabled. Not an issue when charging batteries.

    The Go Power Industrial Pure Sine Wave Inverter part # 34279948 actually calls for a minimum of #4 AWG so I cannot recommend you use #8 AWG. The combined cable length between the batteries and inverter should be no more than 10' long in order to achieve maximum efficiency and to reduce fire hazards.

  • Battery Tender/Trickle-Charger Setup for a 6x12 Neo Trailer
    So it's going to be quite a bit. What you're going to need is to convert your trailer to a 7-way with a junction box # 38656, and then use a DC to DC charger like the Redarc In-Vehicle BCDC Battery Charger - Single Input # RED96FR to use the vehicle to charge the battery that you're adding to the trailer. You're then going to need a small inverter, like the Go Power Industrial Pure Sine Wave Inverter # 34279948, and plug the charger # 329-GENIUS10 into that to go to the bike battery.

  • Determining How Long A 1000 Watt Inverter Can Power 400 Watts Of Electronics
    A 50 amp hour battery is only going to power 400 watts for approximately 1.5 hours so you would need to either have a larger battery bank or a way to recharge the battery. For a larger battery bank you'd really need something around 150-200 amp hours like the # PS64FR. This is pretty expensive so probably not the route you'd want to take just to power some computers. Recharging the battery would require either a generator or solar power, with the generator being the more reliable and...

    To answer your first question, not exactly; your 7 way trailer plug will have a 12v feed but it is only suitable for maintaining the trailer's battery and not actually providing a full charge.
