Hah! I'm an idiot. I remembered wrong. I did some searching to find
whose coach I was thinking of. Turns out it's Jay Darst's, and I mixed
up amps and dollars in my poor excuse for a memory. It was a $1500,
320 amp alternator, not 1500 amps. I was right about remembering it
being hideously expensive, though.

From Jay's post earlier this year:

> power to the inverter to run an a/c unit.

OK, so yes, this is making more sense to me (and probably everyone else) now.

I still think Dorn would be money ahead to fix his genset. Going down
this road the numbers look like $1500 for an alternator, couple grand
worth of batteries, another grand worth of inverter, more for cables
and connectors to tie all that power together... Aren't we approaching
the price of a new Onan now?

-Ryan, going senile wayyyy too early.

batteries in place of generator - Jay Darst - 12-18-2007 16:10

FYI

In my 85 PT40, is a Leece-NeVille 320amp alternator.

That is the biggest I could find in a 12volt alt.

Makes plenty of power to run an inverter powered A/C while running
down the road.

Incidentally, I have run 1 roof air with the inverter WITHOUT the
Detroit running. Run it while at a lunch stop or loading and
unloading.

I have 6 6volt trojan T105s. Thats 660 amp hour capacity of which you
can safely use about 50% when sucking on them with a big draw like
A/C. The roof airs start at about 19 amps and then operate at about
12.5 amps.

That means that 12.5 amps(@110V) x 110 = 1,375 watts
but then inverters typically are around 92% efficient so
1,375 divided by 93% = 1,478 watts so
1,475 divied by 12.5Volts = 118 amp draw at 12.5volts so
if the A/C runs at 100% duty cycle, you should be able to run the A/C
for 2.8 hours.

There are some other factors that will/could cause less run time, has
to do with a high amp draw with no break in the action. Prawlly
internal battery temps and other misc stuff.

You won't start the coach on that battery bank after 2.8 hours. Ya
might start it after an hour if temps are above 70 degrees, which
probably would be, since you're running A/C.

batteries in place of generator - Wilhelmus Schreurs - 12-18-2007 16:47

Ryan:
Is that the sign of old age LOL.

Maybe Dorn would be better off with a smaller generator, 12.5kw is overkill, I
have not been able to put 80% load as it should have, but in my case I will once
I start to travel full time, as my wife is a potter and we will be plugging that
in from time to time, 30 amps 240 volts.
I would think a 6 kw would be plenty, even to run 2 A/C at the same time, and
some load management on the rest.

Hah! I'm an idiot. I remembered wrong. I did some searching to find

whose coach I was thinking of. Turns out it's Jay Darst's, and I mixed

up amps and dollars in my poor excuse for a memory. It was a $1500,

320 amp alternator, not 1500 amps. I was right about remembering it

being hideously expensive, though.



From Jay's post earlier this year:

OK, so yes, this is making more sense to me (and probably everyone else) now.



I still think Dorn would be money ahead to fix his genset. Going down

this road the numbers look like $1500 for an alternator, couple grand

worth of batteries, another grand worth of inverter, more for cables

and connectors to tie all that power together... Aren't we approaching

the price of a new Onan now?

batteries in place of generator - Gregory OConnor - 12-18-2007 18:25

I would heave ho the old genset and replace it with a used RV 5 K
Onan. The construction gensets are not designed to be recontained
and they are noisy. you can find rv gensets all over the place with
low hours. Craigslist.org is a good place to start. I purchased 2 at
an Onan repair facility for under 400. each and ran them with
electric demo hammers for several years.

dumping a hunk of crap aint gonna have an impact on resale. You are
better off with empty storage than a faulty genset as far as that
goes.

I have 6 L16 trogen forklift batteries with major storage. the
problem is when you use it up, you need major runtime to recharge.
proper usage management will help. things like scheduling run/charge
time during high electrical usage demand will maxamize utility with
the least investment need. running the genset twice a day for 1/2
the time will reduce battery storage need. Gensets actually like to
be run fully loaded. Its all Math
