Looking for one to power small items and that I can recharge via AC wall outlet and/or 20W solar panel.
If its not mobil, a good car battrery will do well
Almost any car battery charger will put out 12vdc.
Make sure the Inverter is pure sinewave, not the modified sinewave.
You can get one at Walmart, Radio Shack, etc. Just look at the wattage output to be sure it covers everything you need.
Whoops. Guess I linked the wrong items.
The solar cells need to be connected to a battery via a charge regulator.
The inverter can be powered from the regulators output port.
The cells on their own will not power the inverter.
A car charger can still be used directly to the battery for a maintenance charge.
Really need to know the load you intend to draw. 10W, 50W, 200W, etc.
What works well for some CPF lighting will not work to run a couple desktops and monitors.
Just total up the loads each item draws, if it has a motor, double the load for that item to cover startup draw.
You beat me to it.
Pure sinewave inverters on Amazon.
Now those are fantastic prices.
Merlin are local to me... :)
I have a couple of those.
Looking more at something made for running electronics.
Those are good for jump starting cars, though.
And make sure you have a really good bank of HEAVY DUTY DEEP CYCLE lead acid batteries that you never discharge below 50%. http://www.batterystuff.com/batteries/golf-cart-products/6-volt-deep-cycle/t-105-6-volt-trojan-golf-cart-batteries.html I used a bank of 4 Trojans for any years in Marine duty with great results.
I made a home-made 12V battery pack by connecting some 12V 18AmpHour batteries together in parallel. 3 batteries will give you 54 Amphours of current. I already had 2 12 amphour batteries that I connected in parallel, so I have a 78 Ah battery pack.
For output, I bought a Radio Shack 12v adapter (cigarette lighter outlet) that alligator clips onto the battery. In the outlet I added a dual USB adapter to convert down to the 5 volts that small electronics want these days. Assume you will use included USB to micro-USB cords.
Of course, you could also add an inverter to use for 110V equipment, but that will drain this scale of battery overnight.
