Over the next 9 months we are planning a total of 5-7 nights without shore power (in National Parks). Outside of these two trips, I seriously doubt we'll spend anymore than a single night a year without power. I doubt we will spend more than 2 consecutive nights without electrical hook-ups.
I'm trying to determine what sort of minimal
setup I can get away with that meets these requirements for my family of 5...
- Assume 5p-9a power usage as I expect we will not be at the campsite during the day or during lunch.
- Handle parasitic loads (detectors, radio standby [though I guess I could add a hard on/off switch])
- Water pump usage (several flushes, brush teeth, wash hands, some drinking water and a small load of dishes)
- Minimal camper lighting usage as I plan to purchase a few hockey-puck LEDs and/or LED lanterns to handle general lighting as that approach appears to be much cheaper than replacing the camper's lights with LEDs.
- Possible furnace usage. <-- This is my biggest variable. I suspect it will be needed some, but I'm hopeful it won't be needed all night. "Put on a hat!"
- What else am I forgetting?
Right now I have the stock battery/electrical setup on our new 2012 Roo 233S (single 12v battery, don't know type). And I plan to bring along our Honda EX700c genny primarily for recharging.
I realize there are quite a few variables, but what else do you think I'll need?
I'm thinking I'll need to add some more battery capacity (tell me if you think otherwise) and come-up with a charging strategy.
- Would another 12v do? Should I hook it up or do the "swap-n-charge" game?
- How long would you expect the genny will need to run to top off the batteries each morning?
- I'm thinking I'd just connect the genny to the camper and let the camper's system do the charging. Unless you think a standalone charger (~$80?) and the "swap-n-charge" routine makes more sense.
Thanks for your suggestions...
