pure sine wave inverter

This 12V inverter 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. Plus, the inverter can generate 6,000 starting watts and 3,000 running watts which is a great fit for larger appliances and electronics.


Functions and Features

outlets and terminals on inverter

The inverter includes a hardwire AC terminal 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 400-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 400 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. 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 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.

Review from a similar Pure Sine Wave in RV Inverters


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.

Review from a similar Pure Sine Wave in RV Inverters


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.

Ive used it for a year now on multiple road trips - it is a good product except for terminal locations

Review from a similar Pure Sine Wave in RV Inverters


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.

Review from a similar Pure Sine Wave in RV Inverters


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.


Comments
The inverter is still working great. The 1500 watt inverter will run my 1620 watt microwave. The internal parts of the inverter are top notch. Just had the one problem intially with the cheap plastic case.

Review from a similar Pure Sine Wave in RV Inverters


I installed the GoPower 3000w inverter/charger in my fifth wheel trailer. I connected it with three 12v deep cycle flooded cell batteries and a sub panel to send 120v power to all outlets in the trailer. The automatic switch in the inverter has worked flawlessly. Perhaps the best part is the E-Trailer customer support. They answered my calls, actually speak English, and stayed with me until my questions were answered

Review from a similar Pure Sine Wave in RV Inverters


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.

Review from a similar Pure Sine Wave in RV Inverters


This was a great DIY project. I will be able to boondock and have all the essentials. The inverter/charger was the best addition to my package. I can use a smaller generator because the inverter/charger has power sharing. This is a great feature.

Review from a similar Pure Sine Wave in RV Inverters


Ordered Monday night at 6:30 pm and it showed up Thursday at noon with the free shipping option. Can’t beat that! Now I get to install over the weekend instead of waiting until the original arrival date of Monday. Will give 4 stars for now until it’s installed and working. Hefty unit at 50 lbs. install in my 2015 Amped 28FS looks like it will be very straight forward. Thanks etrailer for the quick shipping. Now I can’t wait to do some serious boondocking especially when my solar is installed and I can minimize the generator running!

The item arrived fairly quickly in good shape. Instructions were clear. My son and I installed it without any issues. It works great and is quiet.

After a year I am still loving it! Before I had a smaller inverter powering 1 circuit for the outlets in the bedroom of my toyhauler trailer, but with this inverter it powers everything in the trailer no problem. The 50 amp pass through works great and charges my LiPo batteries fully.

Review from a similar Pure Sine Wave in RV Inverters


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.

Review from a similar Pure Sine Wave in RV Inverters


Installed easily under a dinette seat for air circulation. Most important is the addition of a large 200 amp power switch/circuit breaker. Also installed remote panel for easy monitoring. This is a nice size for moderate usage of electronic equipment while on the road. Would recommend for its quality and very good instructions.

Review from a similar Pure Sine Wave in RV Inverters


We have had great experience with our Go Power 24 volt DC - 700 watt sine wave inverter. It has low idle power consumption and works great under 120 volt loads. We had bought another Go Power earlier which is a 12 volt DC - 300 watt inverter for a remote lighting application. These are quality inverters with good durability and reliable performance from our experience. I highly recommend particularly the low wattage models we have used.

Review from a similar Pure Sine Wave in RV Inverters


I received the unit lickety-split. Impressive since too many vendors think Alaska is not part of the US..."can't/won't ship to a 'furrin' country!"

Although it's a balmy -4°F outdoors, that's not conducive to doing an installation, so, I opted for a bench test in the heated garage: Temporarily splice in some 14 AWG 110VAC AC cords, one in, another out, clip in the remote control and connect a 12V battery.

The inverter started right up when activated and with an inspection light plugged into the 110VAC output, I put the unit through its paces...i.e., all the permutations of un/plug "shore" power, load, battery etc.

Darned if it didn't behave exactly as I would hope and expect.

The remote & its UI provides all parameters I could reasonably desire and after exploring all of them, played with dis/enabling the battery charger as well as the inverter. All while monitoring the battery with a separate digital voltmeter.

Again, it behaved exactly as I would have expected.

Now, a really thorough pre-installation bench test would involve a 2-pole, 50A "shore" input and load box. Based on what I've seen though, I'm optimistic this unit will work very well as part of a serious solar/battery/inverter upgrade for our "new" used moho, a 2002 Winnebago Journey 32' DP.

When Spring comes next year, and I install this inverter as part of adding serious boondocking capabilities, I'll update the review.

In the meantime, this is an impressively feature-rich, and powerful inverter, and earns a top rating from me.

Item arrived beat to crap bent really really bad I already called in the second I got it and reported the damage I do not have one coming as a replacement yet I am very upset. Words don't even explain how upset I am I should be up in the mountains right now but I went ahead and sold my inverter to someone else because this one showed it had arrived got back to the shop to find out that it has been damaged in shipping.. on your website I can have one by the 26th you guys should have a replacement for me on its way already or have you guys forgotten what customer service is

Review from a similar Pure Sine Wave in RV Inverters


This fuse pairs well with the IC3000 inverter/charger, and handled 4/0 cable with ease. IT is the size recommended by GoPower for the IC3000. Quality materials that I expect to last a long time.

Review from a similar Pure Sine Wave in RV Inverters


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.

  • Troubleshooting Reverse Polarity Go Power Industrial Pure Sine Wave Inverter
    Somewhere in the system you have a hot side and a neutral line reversed. My suggestion is to take it back to the person you paid to install. But if you want to troubleshoot the installation of your Go Power Industrial Pure Sine Wave Inverter, # 34275013 yourself; start at the beginning of the circuit on your installation checking polarity at each connection point to discover where the inverted wiring issue is. You do not state how you identified that there is a reverse polarity issue...

  • Would Go Power Industrial Pure Sine Wave Inverter # 34278157 Work to Power 13.5k BTU RV AC Unit
    13,500 BTU AC units like the Advent part # ACM135C require 1,450 watts so the 3,000 watt inverter part # 34278157 that you referenced would easily cover that. Given the very specific limitations of your situation this would be the best solution overall. A solar panel kit might help too though like with the Go Power part # 34272628 which can provide 200 watts to help charge the batteries.

  • Which Inverter and Power Distribution Box Can Be Paired to Provide At Least 25 Amps of Power
    Part of the challenge of running your RV or trailer completely off battery power is that you're going to require a rather large battery bank (at least 4 and likely as many as 8 depending on the size of the coach and what you're powering) to power things like AC units and refrigerators.

Four Power Sonic Group 27's, # PS44FR, will provide a battery bank of 500 AH as each is rated for 125 AH while consisting of only a slightly larger foot print.
