Portable Fridge & dual Battery Setup

Recently set up a dual battery system for the car to run a 12 v portable fridge/Freezer. The100 A/hr AGM battery is charged by D250S charger via the car alternator when the motor is running in addition to the fridge being powered. When the motor stops the AGM battery powers the fridge. Should be able to run like this for about 1.5 days. The CTEK charger also has an input for the 125 W portable solar cell.

Items and cost
Waeco CF 50 DZ $1200

CTEK D250S DC/DC BATTERY CHARGER $369

Extra Heavy Duty Prostar 12V 100Ah AGM Deep Cycle Battery $354

Eco-Camper 125W Flexible Solar Panel $1400

Wires, lugs, plugs etc. $100

Total $3,423

fair comment, I agree, the good camera I normally use and the wireless mic was at work. I wanted to make the video before taking it down to the car.

The fridge is about 40 W, (3.5-4 amp) when the compressor is on maximum so there is quite a bit in reserve both in the battery and the Solar cell.

Yep will bring it all down, BBQ sounds like a fine idea :>

@sridgway I have added some notes to a flickr picture which may assist

The 1.5 hrs is just the battery alone, the solar cell battery combination with good sunlight would power the fridge and charge the battery continuously.

@sridgway oh wow, so the fridge is only 100 or so Watt. That changes things. Great! Still pricey, but you've gone good gear. You could skimp on the battery and just replace it every year I guess. Hope you'll bring it down this weekend, we can crack a beer and a wine at the BBQ I'm planning.

Is that 1.5 days factoring in the solar panel power as well, or would you expect a little more? I guess if you froze ice, that would be storing some cold, to extend you cooling another 1/2 day or so. But you loose storage space. We freeze bottles of water, so we can drink from them when thawed, rather than use bags of ice, that just cause a mess.
