Fridaynext, Sorry I missed your question on my power setup. Its still a work in progress, I need more power....
Power, like the internet, can't be take for granted while on the road. It takes planning and discipline to make sure you have enough in all conditions. Replacing the light
bulbs that come with a Casita with LED bulbs is a must. If you stay at RV Parks that have Power Hookups, I highly recommend using a Surge Protector like (Portable Surge Guard with LCD Display, 30 Amp - TRC 34830 - Surge Protectors - Camping World
). I've run into low voltage conditions at several parks that could have damaged my electronics or appliances. In the summer especially, when all those rigs with dual ACs start up, the power can dip to 90 volts or less in some sites. All my computer gear is always run off the battery+inverter to protect them, the surge protector protects my appliances and converter.
Right now I have a single Optima T31 Yellow Top AGM battery, two 30 watt GoPower Flex solar
panels glued to the roof (Solar Flex Kits and Modules (Flat, bendable solar) | Go Power!
), a Xantrex 600 watt PureSine inverter, and two 32 Watt folding backpacking solar
panels (32.2W Blue Nylon Folding Solar Panel, Our Most Popular Panel
) I can move to where the best sun angle is. The backpacking panels fold up small enough to be easy to carry in the Casita closet floor. I've had these for several years (before the Casita) and seemed a good fit for the Casita.
I also use a GoalZero Yeti 400 battery (with its own 30w solar
panel) to run the Cell Booster and a few other small gadgets. The T31 battery needs to run the "house" systems in the Casita (refrigerator on gas, LED lights
, water pump) so I offload to the GoalZero to make sure I have enough in the T31 to run the "house" systems. (I'm a huge GoalZero fan and have several of their products, Portable Power Packs - Extreme Portable Power Backup - Goal Zero
I haven't boondocked in my Casita enough yet to really test the capacity, but by my calculations I need to add at least one more T31 to cover for over cast or stormy days. So far I've been able to run my laptop and monitor all day usually 8-10 plus keep my cell phone, iPad, and MiFi charged. This requires that I have sun for 4-5 hours a day to replenish the battery and provide a little extra power during the day. Right now I need to schedule my peak energy use to when the sun is shining. I know I need more power to cover the times when the weather isn't clear and sunny.
I'm in the process of planning for a second T31 battery and a GoPower folding 120w portable solar panel
(Portable Solar Kits (120, 80 & 40 watts) | Go Power!
). I'm debating where to mount the additional T31. My current thinking is to mount it in the cabinet under the kitchen sink. I don't have the heater option in my Liberty so I have room there. The trailer tongue isn't an option for me and I prefer to not hang anything heavy past the rear bumper. The 2nd T31 should eliminate the need for the GoalZero 400, plus double my external solar panel
capacity. I like the GoalZero 400 a lot and will always travel with it.
I travel with a Honda 2000 Companion generator
in the bed of my truck for times when there isn't enough sun/solar to keep things charged. Also you can't run the air conditioner off the battery/solar. So far I've only used the generator
when I want to run the air conditioner. But I'm currently traveling in northern Oregon and the forecast is clouds and rain for the next few days. It doesn't matter how many watts of solar you travel with, if you don't have sun you need another option to charge the battery(s).
Sorry for the long post. There's a lot more to cover on this topic but this should give you some ideas.
