Yeah bloke. I picked up a couple of sheets of thin galv and an old heavy duty steel shelf at the dump the other day-may come in handy. Probably should've picked up the enamelled fridge/oven trays as well, but I had a full load-a wet/dry vax (potential wet/dry gold vacuum), needed a filter bag (washable one $16), a near new 4 stroke mower, which I already have going (water in fuel) and the blade plate removed, to mount a 3/4 pulley driving a car alternator on it for auxillary 12 volt. (my inverter is 3000w/6000w).
So a 12v/660w generator on wheels. Or 2 alternators= 1320w.....
Basically the battery system can operate like a rubber band to run intermittent heavy loads like air compressor/welder/motor start-ups. I will also make a gas producer to run it on wood.
Alternatively a combustion heater/stove could be configured to drive the 12v generator.
Also picked up a near new 800w microwave, and a tool box full of large ring spanners and Sidchrome sockets. The things people throw away is a travesty. Too many dollars and not enough sense.
Last week I got a gas/electric fridge(good goer-freezes 4l water overnight). It needs a 240v element-$99 at the caravan shop- I got a different unit (150w vs 160w) off Ebay for $5.01- just gonna take 3-4 weeks to get here. If it doesn't work good enough, well I'm only $5 down. Got a 300w inverter coming($28) to mount on the back of it, so I can run it off one of my 200w panels and a battery(or mini-maximiser circuit) during the day.
The old element was throwing the house lag switch- 180 volts going through the fridge body-lucky I was careful.
Also, I have a self-piercing fridge valve coming to have a crack at topping up the big Engel with LPG before I resort to a $600+ changeover unit.
Eventually I want to be able to tell the power company to shove it.
