Renogy solar?
I can get 100 watt RV system through Amazon complete with 10 amp controller, mounting brackets and cables for $229 delivered. Anyone know anything about this company? Thanks......DJ

Hi,
I'll probably regret this, but.....
875 amp-hours of battery bank would get me through five days of my typical energy use, provided I only use my smallest inverter for only laptop charging, without going below 50% state of charge. In addition I get 7 amps of charging in leafy shade, and 3 amps when in a rain storm. If I take the lower number of 3 amps x 5 hours then 15 amp-hours are returned to the battery bank daily. After 5 days that is 75 amp-hours returned to the battery bank. That's enough for another day without generator power.
So after six days of cruddy weather, I'd be forced to start the engine on my class C and let the alternator recharge the battery banks at 70 amps. An hour would "buy" me another day. If DJ upgraded his charging path from the alternator, he could do lots of charging too.
As I am mostly a traveler, rarely staying more than two nights in one location, I have no need for a generator. I run out of grey tank room before I run out of electricity as my RV has an extra fresh water tank (OEM installed).
Here is a "formula" for you to follow:
energy audit result X 10 = amp-hours of battery bank X 60 watts of panels per 100 amp hours of battery bank.
I'd recommend DJ look at Sleepy's truck camper solar install. He doesn't generally use any generator power either.harold1946 wrote:pianotuna wrote:
Hi DJ,
I have no generator and no intentions of getting one. It is entirely possible to design a solar system for even a truck camper that will essentially eliminate generator use. It is a one time cost.
That has to be a truly amazing solar system you have. I have never seen a system of any type that can essentially go for an unlimited amount of time without the need for an alternate means of charging the battery bank if there is not enough sun.:B
You should patent and market that system, it would be an industry first.:S
So in essence you misled everyone, saying that you never need a genny, when in actuality you use the engine alternator as needed.:R
I would love to say I never have to use an alternate source to charge batteries, but I'm not that big of a &*(%.:p
