Functions and Features

go power inverter features

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).


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.


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.

My Gopower sine wave inverter died after about 14 months. I tested, ck’d polarities, voltages, connections and it wouldn’t work. I call Etrailer and Noah said send it back and we’ll issue a new one or order a new one and send the failing unit back for full credit. I ordered one and it arrived two days later. What service. Just need to send the old one now.

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


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


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.

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!

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


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


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.

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.

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.

First timer install. Go Power tech support was well informed and answered my questions and gave good advice. I've been using the system I installed for over a year, and glad I did it myself since I've come across a few instances where it really paid off to know how to configure and debug and what to expect. I've been pleased with the performance and interoperability with my lithium batteries and solar charge controller.

Review from a similar Pure Sine Wave in RV Inverters


The inverter does what I need it to. Charges the battery bank from my solar and wind setup, seamlessly switches from battery bank to shore power/generator. Automatically turns on when supplied with shore power, turns off when you disconnect it. I do wish the charge/not charge setting was “Sticky” between power cycles, but that is minor. Also would be nice to have built in or integrated options for solar and wind dump load.

Ask the Experts about this Go Power RV Inverters



  • Can the Go Power Pure Sine Wave Inverters Be Run Continuously Year Round
    The Go Power Pure Sine Wave Inverters like part # 34273866 can run continuously year round that is correct. That said, the inverter would still draw a small amount of power from the batteries even while not in use. If you wanted to stop this power draw you would simply unplug the dc input but the ac output could be left plugged in. The integrated fan will keep things cools so you don't have to worry about overheating with continuous use.
