AIMS Power 2000 Watt 12 VDC Pure Sine Inverter Charger 120 VAC Output 70A Charger 30A Transfer Switch ETL Cert to UL458 Standards PICOGLF20W12V120V

So far so good. very easy installation, I didn't have any problems with the instructions. This is in a off grid log cabin. replacing a 1750w non pure sign inverter and separate charger/ transfer switch set up. The biggest complaint was if I would turn on a load the power would jump and give electronics grief. The new AIMS is a much cleaner set up being all in one. the charger works much better at keeping my big old Rolls battery's charged with less strain to the generator ( Honda EU3000i ) . I have no more power fluctuations turning on a load. I even tried running a concrete mixer 1700w? on the inverter no problems. My only complaint or suggestion would be I wish it would close the circuit for the line in to the line out when in the off position. So if something failed you could still run on the generator and it would pass though the inverter.here's hoping it lasts for a good long time.

This unit was recommended for my vintage RV, to charge a lithium battery and handle solar power input. It came in on time, well packaged, installed easily, works great AND Aims picks up the phone if you want information. Happy to recommend!

I think this interter/charge is just what I need. However, it seems to have one issue I will be asking for some guidanace on. During two power interuptions at my house, the built in GFI recepticle reset itself (to the off /disconnected mode). Therefore it was unable to provide any power even after the utility power returned. Once this anomaly is resolved, I would rate the unit as 5 stars.

I installed this on my boat while cruising around the West Coast of the US as well as Mexico. My charger/inverter lasted about a season.Here are what I consider the main flaws:1. There is no way to intermittently charge without running the inverter. If you use power save, then the inverter runs when the power goes out, draining your batteries. This is terrible for unattended use, as when someone unplugs the cord, you have a reasonable drain on your batteries.2. The device is too sensitive to AC voltage. Commercial AC is 120 +- 15%. A lot of marinas use that higher voltage, especially at night, to cover losses during the day. Anything over 131 and the charger shuts down, again draining your batteries (see #1)3. There is no power share. This means if you want to charge at full power off a limited generator, you may not be able to run anything else or it overloads the generator.4. It's not reliable. First to go was the power save mode, now the entire charger is not working. The inverter still works but it will soon be a heavy paperweight for me.5. The remote display is almost useless. No amps in or out. No charge state info (it just says charging but it could be in float).I didn't use the auto start features and didn't use tech support since installation was super easy. The manual wasn't great though.

Had a problem with the unit (bypass circuit failed), had to ship it back and have it repaired. To Aims Power's credit, they covered the shipping back to them and for the return (which would have been about $50 each way). Stuff happens, not too worried about it. As far as The Inverter Store, they weren't much help. The price is low, however they just drop ship and never see the product, so the shipping is from Aims Power. They were more of hassle then a help--if I didn't go through Aims, The Inverter Store would have left me hanging for shipping.As far as the inverter itself, I'm mostly pleased. I'm using it in a fifth wheel RV application for various circuits which include a residential refrigerator. Most of the time it's just idling at about 6-8% of capacity to run the refrigerator and will keep everything running from place to place with minimal battery drain for an entire day of traveling, however that's with the minimal charging happening from the tow vehicle. I've run the setup with a heavier load for five hours on two 6 volt batteries in series, paralleled with 1 12 volt battery and only dropped about 1.5 volts overall. The charging function and transfer circuit work as advertised, and the remote panel gives enough information to be able to properly monitor what's happening.The only drawback that I see is the transfer/bypass function--the inverter has to be constantly powered on for the bypass to operate. If you shut off the inverter, the circuits powered by it do not get any power at all. That may be OK, however living full time in the RV with the refrigerator running constantly means the inverter is never shut off. I can't really say if that's a bad thing, and other than putting in a manual transfer function, I don't know what I would suggest as an improvement. We'll see how the long-term reliability is in the application.

Contrary to the advertising and even the manual, this charger DOES NOT support LiFePO4 batteries. There is no setting on the actual inverter for LiFePO4 - and the manual just tells you to set it to the lead acid profile, which is incorrect.This charger does not run a proper CC/CV lithium charging profile in the lead acid setting. It starts to fold back the current quite a bit before the charging voltage is reached, which is the wrong way to charge lithium batteries and will shorten their cycle life over time (albeit slightly, but LiFePO4 batteries are expensive).Also the charger in the 1500W version is only 40A, not 50A as stated in the advertising and the manual.I bought this unit for the UL458 listing because it's going in my travel trailer. It's built like a tank and it powers everything I need it to (I basically got it so I could run my coffee maker while boondocking). I have it paired with an AIMS 30A solar controller and 400W worth of panels on the roof.

Easy to install, easy to setup, excellent performance. Its passthrough mode is capable of seamlessly switching the power supply in milliseconds of a shore power failure without disrupting power to your devices.

Easy install and puts out the perfect amount of power.
