I've been having a bit of a play with the panels and battery packs this morning. plugged one panel into a battery pack a put it out in the sun. Input into the b/pack was up around 14.5 - 14.7. Unfortunately the display only show amps when hooked up to 240v. So not sure of amps output on panel. The other battery pack I put on 240v charge overnight. I opened it up this morning and fitted an anderson plug for my fridge. Plenty of room inside the case for extra cabling, circuit breakers etc. The pack runs 2 x 22a/h batteries. With mods to the inside of the case you might be able to fit larger batteries if needed. The wiring going to the cig. and merit plug is small. I wouldn't run a fridge of it but that's just my opinion. Anyway, it's currently running my 80L Primus fridge at zero degrees, pre-cooled on 240v prior to swapping to the battery pack. We'll see how it goes.
Cheers, Mike.
