I want to setup a stand alone system for charging / running electronics off of a battery bank while camping. I plan to select Deep Cycle batteries, charge the batteries via 1) Solar Panels, 2) AC Charger (when available), 3) Possibly a stand alone generator later down the line. My expected load looks like:
90 + 90 + 100 + 6.68 + 10 = 296.68 amp hours = ~300 amp hours per day (@ 20 hr discharge rate) or: 300 / .9 = 333.33 amp hours (@10 hr discharge rate)
If everything is connected/running at once, I will have a load of 360 watts, or approximately 36 amps on a 12v DC battery. I will probably select a 350 amp hour battery and a 500 watt inverter.

I know how to charge this setup via an AC to DC Battery Charger. What are my options for supplementing this charge with solar panels? Thanks!
- Laptop #1, 90w / 12v = 7.5 amps * 12 hrs = 90 amp hours
- Laptop #2 (wheen needed), 90w / 12v = 7.5 amps * 12 hrs = 90 amp hours
- CPAP Portable Breathing Machine, 150w / 12v = 12.5 amps * 8 hrs = 100 amp hours
- 6 LEDs, 20w / 12v = 1.67 amps * 4 hrs = 6.68 amp hours
- Phone, 10w / 12v = .83 amps * 12 hrs = 10 amp hours
90 + 90 + 100 + 6.68 + 10 = 296.68 amp hours = ~300 amp hours per day (@ 20 hr discharge rate) or: 300 / .9 = 333.33 amp hours (@10 hr discharge rate)
