I admit, I have no idea how I get myself into these things...
So helping one lady with a RV problem has lead to another lady who purchased a "Renogy 1800 watt cabin kit"
http://www.renogy.com/renogy-1800-watt-24-volt-polycrystalline-solar-cabin-kit/
It comes with a Classic 200 Charge controller, and she is baffled by it. I've just got a few classic lites, which would be simple to setup as Plug and play. Can a Classic be set up default, Plug and Play? She is running a 24 volt system, Can she just hook it all up close the battery breaker, then close the solar breaker? Will it default to a reasonable Charging for flooded Lead Acid Battery bank?
She has a reasonable, if undesirable, battery bank of 4 strings of 114 amp hour 12 volt "marine" deep cycle (Walley World Special) batteries. So she is in the correct charging range.
Sorry for cheating and asking the forum here, I could look it up my self, Someone on another forum even linked her the the Midnite video's, but she has some cognitive learning problems...
Hi Photowhit,
From the latest manual for FW version 2056 on page 86;
For 12, 24, 48 V batteries ... Too low for FLA Abs, too high for Float, and essentially NO EQ, as defaults, but if you set it up with better Vs, and it is "Entered", it should be remembered upon power-up.
12V 24V 48V - Battery V
______________________
Absorb (renamed from the "BulkMPPT" in manual)
14.3v 28.6v 57.2v
Float
13.6v 27.2v 54.4v
Equalize
14.3 28.6v 57.2v

I'm shooting for functional, I'm not far from this, I think I have 29.2 Absorb and 27.0 for float...
Looks functional to me, with 4 sets of marine batteries, I'm not expecting miracles from the system...
Good to know!
Thank you Vic! I'll take a quick look at the page and maybe get her to try to read one page.

Ok Photowhit, I do not know the target SG for the batteries, which affect all of the voltages .. the Defaults seem like safe AGM settings to me. And would have guessed that your Vabs would be about 30 V for forklift batteries, which are tall, and often have 1.285 target SG ... Had thought that those Marine Trolling motor batteries might be at least 1.275 SG, but have never measured one.
Nice that you are helping that RV lady. Good Luck, Vic
