All right folks, I think we can say that Rae’s battery bank and whole house inverter set up is operating at full capacity!!! I’m sitting in partial sun with about 12.8V only on all the various monitors and I am not only charging my laptop, but also using it! The inverter does beep when the clouds get really heavy, but just for a second! I still think the DC charger I’m getting tomorrow is my best solution, but I feel soooooooo much better than I did yesterday!
I really want to thank everyone who has given me input on my battery upgrade woes. Every single comment I’ve gotten has given me just a little insight into why things weren’t working correctly, how to fix it, what to expect in terms of performance, etc. I really had all the knowledge I needed and the right tools. The problem was with the execution. Make good connections, folks!
Croft asked me how long I plan to stay here and what my plan is if the weather goes bad. I was able to go 13 days on my old batteries with fewer amp hours in mostly crappy cold super overcast conditions. Right now, I’ve got the rig plugged into the whole house inverter and am running the fridge and charging the computer, for a total of 2.8 amps going out. I have 0.9 amps coming in. My monitor is telling me I could run like this for another 43 hours before depleting my batteries. When I was just running a light last night, I could have kept going for 150 hours before depleting my batteries.
So I have a lot of reserve capacity for cloudy days, especially since I don’t have to run the furnace. I suspect I will run out of water and holding tank space before I run out of power. I can haul water from the icky public bathroom and dump grey water there and I can go about six weeks on my black tank. So unless the weather goes really, really bad, I should be able to last four weeks here as I had hoped to do.
This experiment is going to serve me well since I’ve decided I’d rather not put much money into my property next summer. So I’ll leave here knowing if I stand a chance of lasting the summer without plugging in.
