I have been buying and using all kinds of equipment, accessories and devices for my personal use in technology and in equipping my van, aka My McVansion, as an on the road, mobile tiny house. I've generally researched the items before making my purchases and, so far, I've made, what I would say are, excellent choices. It's time for me to share these items with you.
I have purchased two inverters for my van as seen in this photo. The inverters are mounted on a piece of plywood that covers my 8D8A 245 AH, sealed gel cell house battery. They are located in the storage area under my bunk. Both inverters came from Amazon after researching for best value and reliability.
I will also state that I bought and returned (twice, actually) an inverter from a well-known online and retail "freight" company with stores throughout the U.S. Neither one would do the job I purchased them for. I thought, perhaps the first one was faulty, so I returned it and bought a second identical unit. I actually installed it in the parking lot of the establishment with the same result. So, I returned it immediate. I was definitely disappointed. They were 400 watt inverters.
The first inverter I bought from Amazon, after my initial unhappy experience, was a Thor 400 watt modified sine wave unit, model TH400. It had very high marks in all the reviews I read. It is well built, easy to install and works exactly as it should. I bought it with the express intention of using it to power my Black & Decker 2.7 cubic foot compressor refrigerator. I also intended to add a second 1,000 watt inverter at a later date to use for operating other systems and devices that might require higher power.
The Thor unit worked alright. I say that with less than total enthusiasm not because of the Thor TH400. It has actually performed perfectly. The problem is that I should have realized that the output of a modified sine wave inverter is lower than that of a full sine wave unit. Thus, the start up transient when the refrigerator compressor kicked in would sometimes trip the TH400 into overload and cause it to go into "fault" mode. Thus, no power to the refrigerator. I have used the inverter to power other devices without fail or problems.
So, my advice to anyone planning to use one of the inexpensive "dorm room" style compressor refrigerators, readily available from lots of sellers, is to minimally use at least a 600 watt and preferably a 750 watt modified sine wave inverter.
The Thor TH400 is an excellent piece of mobile power equipment and I will give it five stars. It has a two year manufacturer's warranty for parts and labor.
It's features include:
- Full output power - 400 watt/800 watt peak modified sine wave power inverter.
- Low noise/self adjusting cooling fan.
- Ground fault sensing - designed to protect people against electric shock
- Overload protection - inverter will automatically shut down if load exceeds inverter rating
- Smart Surge Control (SSC) ensures smooth start-up of appliances
- Short circuit protection - automatically shuts down until short circuit is removed
- Thermal cutoff - automatically shuts down if internal temperature exceeds safe design parameters.
The current price at Amazon.com including free shipping is: $43.98
The current price for the Thor 750 watt, TH750 is $65.50 and, for the purpose I use my inverter it would be worth the extra $21.50. However, I had a different plan in mind as I mentioned earlier.
The second inverter I bought from Amazon is the Bestek model MRI10011, 1,000 watt modified sine wave inverter. This is a Chinese manufactured unit and I was a bit hesitant until I did some research and read lots of reviews. The unit is rated at 1,000 watts, however, it will deliver up to 1,200 watts, so there is a margin of error built into the rating. The surge rating is 2,400 watts. So, this unit was more than adequate for my refrigerator. And, as I mentioned earlier, I had planned to add a 1,000 watt inverter to my van anyway.
Once again, the installation was easy. However, I did purchase some #4 gauge battery wires to go from my house battery to the inverter. The wires are only 12" long, so there is negligible voltage loss. Like the Thor, this Bestek operates quietly and cool. It turns on every time without a glitch and it powers the refrigerator with power to spare.
Here are the important facts about the Bestek MRI10011 inverter:
- The unit provides enough power to handle either appliance, plus run an LCD TV, or some lights, etc. Good for emergencies too.
- Dual 110-Volt household electrical outlets provide 1000-Watts of continuous power with 2400 Watts of surge power capability. Rated power: 1000w, Max power: 1200w, Peak power: 2400w. Input voltage: DC12V, Output voltage: AC110V-120V.
- MCU controlled with numerous safety features keeps your gear safe. It will automatically shut down in the event of short-circuits, low battery power, DC input voltage overload, output overload, or excessive temperature. It can resume working automatically after these exceptions eliminated.
- Input & Output isolation avoid electric shock. Three external fuses & built-in cooling fan & power switch. If you overload it, reverse connections, it doesn't blow up, just gives you a red LED to let you know something is not right.
- Comes with battery clamps and car cigarette adapter. Please tighten the Positive (+) and Negative (-) terminals nuts when connecting to car batteries. This inverter is only for DC 12V car use.
I give this Bestek inverter five stars, too. While it only has a 12 month warranty, that was not a deal breaker for me. I've been very pleased with its operation and reliability over the past seven months.
Both the Thor TH400 and the Bestek MRI10011 include the inverters, a cigarette lighter plug cable and a pair of wires with alligator clips. Both sets of wires have terminal lugs on the inverter end. Both include simple instructions. Both units claim an operating efficiency rating of about 90%, which is average for a modified sine wave inverter.
At this point the Thor is pretty much surplus to my requirements. I've actually found I have less use for 110 VAC than I originally projected. I use 12 VDC (or propane) for operating almost everything I use in the van other than the refrigerator. My laptop computer is even powered/charged from the 12 VDC circuits. But, for the foreseeable future, I'll keep the Thor TH400 mounted in the van next to the Bestek.
If your AC power requirements are minimal and low enough, I'd highly recommend the Thor TH400 and that's from my personal experience. I wouldn't plan to use it with a "dorm" type compressor refrigerator. It's reliability is spotty in that usage.
If your requirements are higher (and definitely if you are going to power a "dorm" style compressor refrigerator), I'd opt for the Bestek MRI10011 thousand watt inverter. For not quite twice the investment, $79.99, you have 2.5 times the power available.
There are lots of inverters in the market and I looked at a lot of them. Some were priced higher and some lower. I usually look for the best value when I am investing in something I plan to use for a long time. I'm completely happy with my selections of these two inverters and, should you choose to purchase one of these units, I'm sure you will be, too. Of course, Amazon offers a 30 day return policy, so that's an added measure of consumer security. But, always check in advance to make sure of the return policy on the specific item you're buying.
