Review on ⚡️ ETL Listed AIMS Power PWRIX200012SUL 2000W Pure Sine Inverter: 12VDC to 120VAC with Transfer Switch by Brian Rogers

UPDATE 12/17/20: It's still not possible to get an inverter to power small appliances. So I removed it from under the cabinet and moved it to the storage space under the floor next to the batteries. Opened up the sealed bottom of the TT and ran an 8AWG wire from the shore power plug to the inverter's 120VAC input, about 30 feet of wire. I then ran the 8 AWG wire from the 120 VAC inverter output back to the power panel about 25 feet. Three 100Ah batteries reconnected with 2 AWG cable wires connected in parallel. I connected the battery to the inverter. All this to reduce the length of the cable between the battery and the inverter, now it is less than 4 feet. After everything was plugged back in I unplugged it and tried the 1135w microwave and it worked as expected, the toaster and coffee maker did too. It would have been nice if the installation instructions had talked about wire gauge and spacing issues as it would have reduced the frustration I was experiencing. To be fair, AIMS support suggested early on that the problem might be with the TT wiring; however, did not recommend any changes to fix the wiring issue. The inverter was originally installed by a dealer using 12AWG wire which was too small to handle the current load. My "education" that finally solved the problem came when I turned to the Dutchman forum for help. I can now change my recommendation to BUY with the caveat that you need to understand the relationship between wire size and wire length. Just as the size of a hose determines the maximum amount of water it can carry, the size of a cable determines the maximum amount of current it can carry. Finally, this inverter must be installed close to the battery, and the wire gauge from shore power to inverter and from inverter to power panel must be large enough to handle the load you want to power. If your batteries are close together, use at least 2 AWG wire to connect them to each other and to the inverter. From my research, any 120V AC coming from the inverter for more than 5 feet will require a larger AWG. As I mentioned earlier, I was able to use 8 AWG for 30 and 25 foot distances. The only reason I didn't give a 5 star rating is that the instructions and support should better explain installation issues and how to overcome them. Problems when the inverter does not work. UPDATE 01/11/2020: On the advice of AIMS support, I removed the inverter from the trailer and prepared it for shipping to technical support. Since shipping both ways was very expensive as AIMS doesn't pay for shipping, I decided before that to plug it into my desktop. I plugged it into a fully charged spare RV battery and connected the outlet to the inverter's 120VAC output with a 12AWG wire. I connected a toaster (750 watts) and a coffee pot (800 watts) in series, turned on the inverter and both worked fine. I reinstalled the inverter in the trailer and hooked it up to the power center (10 AWG wire) and installed a new 15 amp circuit breaker to keep the toaster and coffee pot on their own circuit and hooked up the new outlet to the circuit breaker . Neutral and ground rails use 12 AWG wire. Plugged in the toaster, turned on the inverter and tried to use the toaster, which immediately caused the inverter to fail. All other circuit breakers on the power board except the main circuit breaker (30 amp) and the new circuit breaker turned off; tried again and the inverter immediately went into an error state. All connections checked, all connections were tight. I spoke to our local RV dealer and they have stopped using AIMS inverters. now they use furrion as they had too many problems with AIMS inverters. Since I can't get this inverter to work when it should, I'm changing my rating to one star and a DO NOT BUY recommendation. AIMS support is 5 stars, but paying over $200 to ship the inverter to AIMS and have it returned under warranty just doesn't suit me. UPDATE 9/30/2020: The inverter works with my CPAP, TV and DVD player, each of these sockets shows 119VAC so I know the power supply is correct. However, the inverter will not work with a single vent coffee maker (800W, 120VAC, 7A), toaster (750W, 120VAC, 6.25A) or microwave oven (1135W, 120VAC, 9.5A) . The inverter is rated for 2000W when running and 4000W when starting the device; the burst usually lasts only a few milliseconds. The microwave turns on, but turns off after 20-25 seconds; Since the "spike" occurs at startup, I know the inverter will handle the surge with ease. The coffee pot and toaster will turn on for less than a minute and then turn off when the inverter reports an error. I have plenty of power: three deep cycle 12VDC 100Ah RV/boat batteries connected in parallel with 2 AWG wire. Batteries each indicate 12.8V DC; 12.8 VDC inverter input 12 VDC power and 119 VAC power at the output of the inverter when using a household battery for power supply. I worked with an AIM engineer via email to resolve this issue. The customer support is fantastic. very quick replies to emails. Today an AIM engineer asked me to call me so we can try to identify the problem on the phone together as the microwave, coffee maker and toaster are within inverter specs. (Update: no support call) UPDATE 08/25/20: Wanted to see how a single 100Ah 12V DC battery could power a toaster and coffee pot. It doesn't matter if the microwave is working or not at that moment. This didn't solve the problem. Two additional 100Ah 12V DC batteries purchased and installed. Dealer installed 60 Ah battery removed. This battery pack (3 x 100 Ah) can deliver 3600 Wh at 12 VDC; should be more than enough to power a toaster and coffee pot. None of them require more than 7 amps at 120 VAC. I should be able to use both for a few days before needing to charge the batteries. The inverter still wouldn't start the toaster and coffee pot. I decided to contact AIMS support again. They said it was a wiring issue in the trailer, not the inverter. UPDATE 4/10/2020: There was an issue with the electric converter in the trailer turning on when running on domestic batteries. AIMScorp sent me a diagram showing what caused the problem and how to fix it. All I had to do was unplug the power cable from the power panel to the inverter and connect it to the inverter's shore power input. Did that and problem solved. Aimscorp support is great. I highly recommend them. If you have any problem, they will help you solve it very timely. UPDATE 3/30/2020: I ran into some issues and contacted Aimscorp.com tech support. The seller has made it clear that there is no support beyond Revain's 30 day return policy. Aimscorp customer service was very helpful in explaining what could be causing the problem. It turned out that the problem was not in the inverter but in the trailer junction box. February 17, 2020: Purchased to provide limited 120VAC power supply when not connected to shore power. I wanted to be able to use the microwave and electric coffee maker in the morning. I bought a 100Ah battery to use in combination with a parallel connection to an existing battery (60Ah). Worked as expected from shore power so far. The build quality is very good and the installation was very easy as I am good at electrical wiring; However, if you are unfamiliar with electrical wiring, hire a professional to install it. I had to identify the shore power connections in the electrical panel prior to installation, that was the hardest part; After that, it remains only to connect everything. The instructions are in pictures, you need a magnifying glass to read them as they are very small. Contacted the manufacturer for some information and they were very helpful. I highly recommend this product if you need 120v AC on your boat or trailer.
