help to derive max ac amps setting for inverter
|

| lovingit69@gmail.com 2006-11-06, 3:25 am |
| I am setting up my inverter to charge the batteries and It requires me
to set the MAX AC AMPS which should effectively be set at the AC
current which will trip the breaker on the generator. Problem is that I
can't see that anywhere in the user manual for the genny. Am hoping
that one of you will be able to help me derive that from the specs of
the generator. Which are:
V240
Max load 1100w
And there was a figure somewhere I saw that said 1100voltamps.
Basically can anyone tell me what Amp value I should enter if I want
the generator to put out say 1000w?
I kind of figured that it should be 1000w/240 = 4.16amps but that seems
very low.
Any help would be very much appreciated.

If it is a 240 volt generator, your calculations are correct.

Maybe you should explain more carefully what it is you are doing and
what you are working with. Is this a generator with a DC output as well
as AC? Please DO NOT hook up the AC output to a battery!

Well, a 1000W generator is very small. 4.16 amps at 240 volts is correct.

Thanks for that.
On this matter...can you explain something else to me? Am I right in
saying that 4.16v @ 240 is used by the charger to theoretically charge
the batteries (forgetting any loss) at 41.6amp @ 24v?
Thanks everyone for your help......much appreciated.

Yes --- that is correct, if you disregard line loss and conversion losses
and don't forget the way batteries charge, it takes along time to get that
last 20% into a battery
