When batteries are not cycled nightly, then they do not need to be held at absorption Voltage each day for any amount of time. At absorption
voltageor higher. And especially when hot ambients exist is when they use the most water.
When you leave and no longer cycle the batteres, Reprogram absorption voltage down to float voltage. Or if you have a duration option. Set 14.2v for
no more than 15 minutes.
When you return and start cycling the batts. Return absv to normal for about 2 hours.

So, what time is coffee usually ready?

batts...omg !!
one of the MOST understood things around !! lets deal with the most common type : flooded lead cell...a float charge is normaly 13.2 V
(mantanice)...charging is up to about 15 V and gassing will occurs (sulpher) on leads plates hopefully be removed (not guaranteed) and NEVER let you
batts get below 12.6 V BTW heat is a big killer of this type of batt and a temp sensor is a very GOOD thing...not a BS gig at all.....I deal with
batts daily in my biz and the stuff I see is.....f,ing nuts !! there is NO outboard mad
e to run a deep cycle...FACT !!! last month I replaced 4 stators due to the most common marine misconception !!! I know someone will TRY and argue
with this simple FACT!!!

heh, I know, but I have lots of excess right now. If I ever get another freezer then that will have to go and I'm back to stove-top.
Very strange WS for sure - I would have bet on a So Cal freeway series.....can anyone explain the Dodgers????

I have no choice but let my batteries go below 12.6 when they are under a heavy load...especially at night. but they are not in my boat either.

It all depends on how much capacity your system has. I make coffee with electricity, I also run a 1 ton mini split AC unit in the summer time at
night. I also have 7000 watts of panels, 7200 watts of inverter power(Outback) and 1160 ah of 48 volt HUP battery. Next I'm going to try to power an
RO system to make my own fresh water. That will need another 2 kw of panels.

That is a huge battery bank! That is also a huge array. Good for you. Love to see your system sometime. Are you going to try the RO system just to see
if you can do it or is drinking water that expensive down there that it will cheaper to make your own?

OK.. I'll admit it. I use an electric coffee pot as well... Maybe thats why my batteries dip below 12.6v sometimes.

Larry, come on down our way any time to see the system. We get our water by pipa (water truck) and they are easily the most unreliable people in
town. It's not expensive but it is the source of much frustration trying to guess if the truck will show up or not. I like being self sufficient and
water is the remaining tie with outside service. Oh, I take that back, we also get propane delivered but they are totally reliable and we only need it
about every 3 - 4 months.

You guys have it so easy down there. If we want water, pila water, we either have to go get it ourselves or pay a $100 US to have it delivered.
Propane is delivered but not very reliably. Sometimes they don't show up for 2 or 3 months. People using small tanks can exchange them in town but
those of us with the stationary tanks need the truck. Anyway someday I just may show up down there and see your stuff on my way to Agua Verde.
