I currently have a standard grid tied mains system which runs through a standard inverter, but I have recently been playing around with some extra camping equipment to try and run some household stuff to further reduce my energy bill without investing majorly in new equipment.
To that end, I have:
1 x 200W 12V solar panel
1 x 30A 12/24 solar charge controller
6 x 12v batteries of different sizes, recovered from self propelled golf buggies
2 x 1050W continuous UPS inverters without batteries
I've managed to rejuvenate all the batteries so that they hold a charge of 12.5V or more and have them hooked up in parallel
My idea is to use the solar to charge the batteries during the day and then through the inverted, run the fride at night when the mains solar system is not feeding the house.
One of the problems is that the UPS inverter has a 48V input. I could of course hook up the batteries in a combination of parallel and series to get 48V, but I wouldn't know how to charge them. Manual switching is not an option as they are in a hard to reach place and this would be too complicated when I'm not around.
This is really just messing around with recycled parts, so I'm not really looking and making a huge purchase of equipment, but if there is a reasonable solution, I would be interested.
Regards,
Mark
