I few years ago I bought a 40W solar panel from Yahoo Auction Japan for my tiny prefab at work. For years I have been using generators to power up my tools and sometimes I even use a DC/AC converters hooked to my cars just to get some juice to power-up lights. One time I hooked my DC/AC converter to power-up my vacuum cleaner and the vac killed the car's ECU... HAHAHA!

I asked the power guy if he can hook electricity to my prefab and his price is just too much. The only thing that he has that I don't have is the license for hooking-up the power. I have been playing with 240V since I was 7, I climbed electric posts and towers, have played with high voltage and even got electrocuted several times and this guy said that I have to pay around 100,000 Yen. I refused and he offered me that if I do all the work (building the pole, installing the meter, hooking-up the wires to the power pole, and doing all the set-up by myself) and all he has to do is to make it legal, he'll give me a 10% discount... I refused and showed him my huge generator which is enough to run a welding machine.

This is the reason why I stay off-grid because I don't like some wise-ass telling me that I have to pay a lot for his services that I know that I can do myself...

inside the prefab

This is how the wiring look inside the prefab. I made it this way so that I could dismantle it easily when I need to remove the charging unit. 

Top right is the voltage regulator. White switch is just an ordinary house light switch. The black lamp on the left is my back-up lamp that originally came from a Mitsubishi Pajero. It is 12 volts and have cigarette lighter socket. All the electrical wires came from scrap.

The batteries are all 12 volts. The two bigger ones are for cars and the two smaller ones are for motorcycles. All of these batteries came from my battery junk pile. The blue box on the lower left is my cheap DC/AC (12V to 100V) converter w/c had a cigarette lighter socket. The wires on the lower right is for connecting the DC/AC converter to a battery. The cigarette lighter socket came from my scrap Suzuki Wagon R and the alligator clips I bought from a hobby shop.
