Hi Folks,
If anyone that knows how to design my DIY solar I would be more than happy to pay for it. I bought the book and can't get very far. Here's the run down of what I have going:
Dodge Caravan, I stripped the inside to bare metal and will soon be done with the sink, plumbing, woodwork but I need to plan the solar. (side note): I thought I'd be done by last Christmas, then certainly by summer and now I'm hoping I can finish before I'm too old to drive I'm 61 years old.
I pulled the trigger and ordered a NEW 4 piece 3.2v 280Ah Lifepo4 (see spec below). This is way more than I need, my energy audit was about 150Ah.
This is what the spec sheet said: Model: 3.2V LiFepo4 280Ah, Real Capacity280Ah, Nominal voltage 3.2V, Maximum Discharge Current 280A,
Max charge voltage 3.65V, AC Impendance Resistance < or - 0.25m ohms. I ordered the battery from AliExpress from China so it'll be a couple months before it makes it to me in Tennessee.
In the book it says find the "maximum safe charging rate" in amps and as long as the maximum power produced by the solar panels is less than the maximum charge rate of the battery bank, we will be good to go. As you can see from the specs it shows the max charge in voltage 3.65, not amps, I don't know how to convert this.
There will be a rack on top the van so fitting enough solid panels will work. (how many and what size though?)
That's as far as I've gotten. please let me know if you would like to blueprint this start to finish and how much you would charge me. The batteries and all accessories can be placed very close to each other inside the van. 3 feet apart max.
Again, I have Will's book and the "Classic 400" design is probably close to what I'm after so that info is at my finger tips.
Thanks very much, Mike Embody
P.S. I may not be very smart but I can lift really heavy stuff
Here's the link to my order, the spec are towards the bottom:
