I'm on week 5 of a multi-year camping trip in North America. I'm able to make this trip because I do freelance writing work from the laptop, which can be done anywhere with an internet connection, and in many cases, places without.
My base of operations is a 1993 4runner, and my primary laptop is a Lenovo Y500 that pulls 30-100 W. The transformer block puts out 19.5 V @ 6.15 A. I want to built a 5V power supply (detailed in another thread), and in addition to the 5V, I want to build a secondary 12V system separate from the main car battery. I'm thinking of getting a 100 Ah deep cycle battery with a 600 - 1000 W pure sine inverter to power the laptop transformer, a rice cooker (450 W), and possible eventually a 120V / 12V fridge/freezer.
A couple questions:
- I've already spent several hours researching inverter / battery combinations and I'm still not sure what's the best buy. I was looking at two 600 W inverters:
http://www.amazon.com/dp/B00AYH6BSO/
http://www.amazon.com/dp/B003FWNWN2/
and two 100 Ah batteries:
http://www.amazon.com/dp/B00S2MDZFK/
http://www.amazon.com/dp/B00S1RT58C/
And additionally I want to buy a battery monitor (http://www.amazon.com/dp/B013PKYILS/ ?) and get the right kinds of cables (4 AWG?) and I'd love to install a relay shunt that I can toggle so that if the main car battery dies I can connect the two 12V systems and start the car off the secondary system.
So what do yall think of these selections? Do I need inline fuses? If I'm going to be expanding in the future should I jump for a 1000 W inverter system? Are the pure sine Samlex inverters overkill? Would it be worth trying to wire up an arduino control circuit for this plus the 5 V system? Is this all crazy?
