Inverters R Us Blog

By: G. Gipson

My wife and I decided to get back into the recreational vehicle camping world again. I remembered that after just about every trip we took in our high end motor home I had to fix something so we made the decision to keep it simple this time.

We chose a small tear drop trailer and considered a small 2kw generator for those times we needed AC. The things are noisy and they pollute so we ruled that out. Instead I mounted a couple of solar panels on the roof, hooked them to the battery though a controller and installed one of your 2KW true sine wave inverters instead.

I only want to run a hair dryer and charge my laptop computer. Although the existing 12V battery is adequate I plan to change it out to a couple of golf cart batteries for more use time.

Wow, are we happy with the setup. No noise, no smell and free electricity to boot. We could not be happier with the way this works. No moving parts to ware out and no down time. I have enclosed a couple of pictures showing the installation. Enjoy.

This is what my AIMS 1250 Power Inverter runs and more about my home solar system:

My AIMS 1250 runs a small freezer that I bought at Wal-Mart that opens from the top to keep the cold air from flowing out. I put “blue ice” in the freezer and only have to run it 1.5 hours a day during the winter and 3 to 4 hours a day during summer to keep every thing cold.

I have a desktop computer, but have switched to using a laptop because it is more energy efficient. I also have a: printer, scanner, and other computer stuff.

I replaced my old 19-inch tube type TV with a 17-inch LCD TV that is more energy efficient (I save about 100-watts or so).

For air-conditioning I use a Swamp cooler that I gutted the ac motor out of and replaced with an old car electrical radiator fan but left the ac water pump in because it doesn’t take much power to run.

For cooking I use a countertop stove that a 5-gallon tank of propane will last about 9 months. I just use the Honda generator to run my washing machine and to top off the batteries on really cloudy days and during wintertime when the days are short.

I do have to conserve some. I don’t run stuff like electric: heaters, ovens, irons, or things that take a big drain on the batteries. I do dry my clothes with a Thermonuclear Device (Clothesline). What about hot water? I have plans for building a Hot Water Solar Collector.

What about heat during the winter? I have a wood-burning stove and one day will build a Solar Collector for that too!

All my lights are LED 12 vdc and draw about an amp, but I could run ac lights (Compact Fluorescent) if I wanted to. The LED’s give me enough light to navigate around the house and for reading. I also use them outside on a timer. I don’t have to turn off the LED lights when not needed because they use so darn little energy, but I do it byhabit.

My system consists of:

My thoughts on how to get started:

There are several ways to begin a solar electric system. I will tell you how I would begin one. First you have to look
at all the electrical stuff you have and the power that you consume.

Find ways to make them more efficient or get better ones that are.

Remember that the less power you consume the less costly your solar electric system will cost. Then after that and depending how much you want to spend right off you can start planning.

It’s good to start off with a generator, like the Honda I have. You can power some of your home with it in an emergency.

Next step would be to get a dc to ac inverter, AIMS makes a good one, and your L16 batteries. Now what you have just done is incressed your time off the “GRID”. You can charge your batteries with the generator and when thats done turn off the generator and run just off the batteries.

Now you can get your solar panels and controller. Yournot sure how many you’ll need? No problem. You can keep adding to it as you go along.

Thats it, you have just gotten yourself off the “GRID” and you are now your own power company…..Of course this is over simplified version, there are building codes, where to put panels, wiring the batteries, 12, 24, or 48 volts dc, sine wave or square wave inverter and stuff like that, but these are the basics. This is just what I did and it works. You should get an electical contractor if your not into do it yourself projects.

My thoughts about solar power:

Some people will argue that Atomic energy, Television, the Internet, or whatever were the greatest inventions of the 20th century. Well now, lets take a look at solar electric power. It’s inexpencive, easy to use, no moving parts, just sits there and produces electric power. Done, end of story. No not yet, it was invented in the 19th century, 1839 to be exact by Edmund Becquerel, a French experimental physicist.

I am not going to write the history here for you, I just wanted you to know that it was created a very long time ago.

What I am trying to say here is that “IF” solar electric power were invented today… with our energy industry is such a mess and customers being held hostage by incressing rate hikes… and “IF” you heard about a new energy invention that you could buy and install yourself, that just sat there with no moving parts and could produced enough power to run your home and you wouldn’t have to pay or depend on Power Company again. What would you do? Now that’s end of story! It works, it’s here, use it!

Hi, my name is Nxxxxx Wxxxxxx and along with my wife, we own and operate San Ysidro Farm of McNeal, Arizona. We raise grass fed lamb and beef and “farm-raised” pork. We mostly sell at local farmers markets.

I have a 6×12 cargo trailer that I have turned into my “market” trailer. Inside this trailer, I have four 6 volt golf cart batteries that are wired into two 12 volt banks. The 1250 watt inverter is connected to these batteries. I have a 10 cf freezer and a small refrigerator inside this trailer that run off the inverter. I also run some other items such as a light and a cash register. There are times when I let another vendor at one market connect her freezer as well.

My truck charges the batteries as I go down the road. When at home, I put a regular battery charger on them and put the freezer on “house-current”. Soon, I will be installing a solar panel on the trailer, so when I’m at a market the inverter is getting some of its power from the sun.

The 1250 watt has been a great inverter. I had a 1500 watt from another source but it could not handle the bouncing and jarring from going down the road. I had set this 1500 up as my main power source. We were going to a new market and things were pretty hectic, but something told me to take the 1250 along as someone might need some power for something. Well, I get set up at the market and noticed that I had no power. The 1500 had crashed, it had lights but no juice. I grabbed the 1250 and put it on the batteries, turned it on, plugged things in and it worked great. Now it is mounted in the place where the 1500 was and is working great.
