Xantrex Prowatt SW2000 2000W True Sinewave Inverter Model# 806-1220

I recently converted a 5 x 10 enclosed trailer into a travel trailer and was looking for a small pure sine wave inverter to power a small refrigerator off of two reclaimed wheel chair batteries while I was away from shore power. After MUCH online research I decided to go with Xantrex as they have good reviews and reasonable pricing.The PROWatt 2000 Inverter (Model# 806-1220) arrived on time and as described. Item was very well packaged, showed no signs of damage and came with all the accessories to make installation quick and easy. It has a sleek and compact design and I especially like the display as it alternately shows the power being used and the remaining battery voltage. After installing the inverter. and much to my surprise, it easily powers a 1.3 cu/ft refrigerator, clock radio, 19" TV and a small AC/ heater combo all at the same time. The only two items I can't run at the same time are the microwave and the AC because the microwave requires 1500 watts to start. No big deal as I only use the microwave for 5 minutes or less anyway. The cheaper 2500 watt inverter that I've had for many years wouldn't even get the refrigerator or AC to run properly as it is a modified sine wave unit. Pure sine wave is definitely the way to go! After having the inverter for several weeks now I'm very happy with its design, price, and performance. I have already recommended it to several of my friends.

I see a few complaints in the reviews about having trouble with high-load applications of this inverter. I bought one about a year ago, with the intent of using it to get solar-powered air conditioning in my RV. I made it work, eventually, and the problems I encountered had nothing to do with the inverter (which supplied 1500 watts sustained load and handled the surge of starting the AC, once I got everything else working).First of all, wiring: Everything will tell you that 4 gauge should be more than big enough: Not even close. I tried 4-gauge. Then I tried 0-gauge. Then I tried making the wire runs shorter. Then I started doubling up wire runs in parallel. By the time I was through, my battery interconnects were double and triple 4-gauge in parallel, and the connection to the inverter (coming from the center battery of 5) was 000-gauge (also known as 3/0). Connecting that to the terminals on the inverter required taking an industrial terminal block normally used for substation wiring and drilling a 3/8" hole to connect it to the terminals. Finally I had something that wouldn't drop 2+ volts over the wires when drawing 125 amps. When they say 4 gauge can pass 200+ amps, they mean that it won't melt the wire, not that it will give you a usable voltage.On top of that, batteries: Lead-acid batteries may say they can deliver huge numbers of amps, but not without huge voltage drops. In practice, for every amp you're drawing you want at least 2 pounds of battery (so, minimum 4 size 27 batteries to deliver 125 amps needed for 1500 watts). Try to power your space heater off something you can pick up assisted, and you're just going to get a lot of annoying beeps.And don't forget that after you've drawn off half of the amp hours theoretically available in your batteries, your *maximum* voltage will have dropped to around 11.8 (so battery load and wiring losses will be working from a lower baseline). With 5 type 27's, I could run the original rooftop air conditioner for no more than 1.5 hours before they were too far down to provide 11.0 volts under load. So I figured out a way to mount a modern, high-efficiency unit that provided the same cooling for half the power.The point here is that with a really big inverter, you're pushing 12V right to the absolute limits, and you have all *kinds* of weak points that will keep your system from working properly. These are really intended for big residential solar systems with batteries in the thousand-plus pound range. This inverter works *fantastically* well, now that the rest of the system is properly supporting it, but even for an experienced electronics tech getting all that arranged properly was quite an education.

Low idle current of around 350mA, which is much lower than others.But...let's say you reversed the DC power leads? Huge sparks, and dead inverter? Yes, but you can fix it.You need about two hours, a Weller 260W soldering gun, a solder-sucker, and 10pc of 25A mini-blade fuses.Once you open up the case (about a dozen screws), you'll find 10 of the 25A fuses soldered to the board in two groups of five. Use the Weller gun to heat the solder (on high), and with a solder-sucker you can clear the solder, one spade at a time. Then solder in 10 new fuses. That part should take about an hour. Bolt it back together, and it'll be as good as new!

In judging a company by how well they do dealing with occasional problems that will happen with all devices, Xantrex in surprisingly good. Bought the Xantrex PROwatt SW Inverter just over 2 years ago. The warranty was for 2 years and it worked perfectly within that 2 years. 6 months later I noticed a loud buzzing noise & slight odor of smoke when the unit was off. I had to disconnect unit from power to get it to stop. It was out of warranty, so I called the company to see if I would be able to fix it on my own, or trash the unit. The Tech had me plug unit in so he could hear the noise, and test to verify unit still worked, (it did).After verifying purchase, he then wrote up a ticket and sent me a new unit. It was completely unexpected to have any company's customer service go above and beyond. The new unit is in and again, working perfectly. I would give them 7 stars if I could.

I use this 2000 watt inverter in my RV when I Boondocking. I use the power from my batteries that is being charged via my solar panels. I do have a generator but it’s so much nicer when you’re camping in the wild and you don’t hear a loud generator running in the background. Very good product easy to install. I recommend this inverter.

Très bonne appareil très solide et fonctionne très bien , puis facile d installation

Very Well built inverter.Very conservative rating.Will work in very harsh conditions and perform well.

I should have read the more technical reviews here on Amazon. This inverter has been in production for over 15 years with little to no updates/changes in design. This 1800 watt (3000 peak) inverter does not handle inductive loads very well such as my 990 running watt shop vac, where as my old Renogy 1000 watt inverter does. The Renogy is not perfect at starting the vac either, but once running it sounds like household power where the Xantrex Prowatt sounds different. The voltage on the Xantrex drops as load increases. It is down to 110 volts from 120 at a 1700 watt load. Still within specs though. This inverter runs simple resistive loads up to its 1800 watt rating just fine like coffee maker, toasters hair dyers. It barley starts/runs my 700 watt(cooking power not actual power) microwave (which does have a high starting current). Depending on your battery type, cabling size and SOC, when it shuts off due to low dc input voltage it turns back on immediately as voltage recovers then off and on continuously. This is not good for your compressor starting and stopping every one second if you are not there to shut it down. A cheaper technologically modern inverter may probably be better. Hopefully this one is built more robust than the newer ones. It does well for resistive loads. My other cheaper inverter had more peak starting power for inductive loads. You do need more inverter for inductive loads. When they rate peak wattage some companies use 3 seconds at peak, others use 16 -32 ms. Most can hold 10% over continuous rating for 5 minutes. There is no standardization in ratings.

Installed this inverter to provide battery power to my electric stove while anchored out for the night. Very good product.
