Thread: My portable 12v solar power project

wait till you see the gallium panels currently being tested before the release. truly amazing. about 4 times the output per square meter even in dim light.

looks great @GWH , impressively tidy work

can you explain more or give us a link about these panels @gonetropo ? cheers

Yep no prob, will itemise the major bits and post a bit latter.

Righto

It normally pays not to add up the cost of these 'little projects'......

MTM AC11 Ammo box was $30
2 x 12v 22ah AGM deepcycle SLA batteries were $177 the pair
2 x 30W solar panels plus 10amp PWM solar controller were $150 for the lot
Fascia panel including volt meter, cig light socket and dual usb socket was $24.50 (i used 2 of these)

Add another $150 for smaller things like 3 inline blade fuse holders, switches, terminals, electrical cable, 2 x Merit sockets and plugs, 10 meters of decent dual core solar cable and connectors, and a cheap 240V 2amp smart charger, so i can plug that in and charge up at home without fuss if need be.

I could have done some things a little cheaper, ie could have got a cheap 240V extension cord from M10 and cut the ends off that and used in place of the more expensive solar cable from Panels to Battery box. But i wanted it all to be right.

Thanks
Is a cool little setup which I'm going to poach

Going to get the mrs to sew up a carry/protective bag for the panels and line it with dense foam matting.

Yes,some portable panels in Oz come like that.closed foam mat sewen between canvas type stuff,two zips meet at the carry handle.

looks great.

came across these guys reading up on the gallium panels. having a durable roll up panel option would be excellent for this type of set up
