Hello, first-time poster here.
I have an RV that had an old battery charger
. Based on opinions I found here and elsewhere, I decided to replace it with a ProNautic 1230. That's why I'm here, this forum seems like a better resource than anything dry land-specific. The install went fine, and everything is working great from what I can tell.
EXCEPT: When it's charging
now, with temperature compensation on, I see the voltage getting up to 15.2V, as it should. But the way I have it wired, the house appliances
are seeing this same voltage. The furnace in particular is blowing really really hard, and I know this isn't good for it (It's speced to run up to 13.6V).
It seems like this should be a common problem, yet I haven't seen any solution in all the research
I've done. No diagram I've dug up of RV or boat wiring
seems to address this. Do others just let the house appliances
run on higher voltages?
It looks like I might be able to solve the problem with a DC/DC converter like this:
8-40V to 12V, Step-up + Step-down, 120W : Current Logic, Expert of DC-DC Converter
Says it takes in from 8-40V and outputs 12V. I think 120 watts would be enough for my modest needs.
But I am curious what others may have done.
