[RE-wrenches] AGS sensitive battery charger

[Bruce Geddes]

What about the Morningstar Relay Driver?  You could use one port as battery
voltage sense, another to control the gene start relay, third to sense
generator voltage and 4th to control AC relay via a timer to allow generator
warmup time.

Yes, but how do you integrate a sensor with an Iota?  And I don't think they
make a 30A (or higher would be fine, he's got a bigass generator) 48V
charger....   I got ears, but I've never heard of such a thing.  It just
seems like a damn shame to buy a big inverter when I just need a decent
charger with an AGS module!  But I'm not technically inclined enough to rig
some voltage-sensitive relay, or the like.

We are not really advocating doing this.  It can cause nightmares in service
and support.

If one really knows what they are doing, it can be done (and has been done)
but mere mortals should not
be attempting to do this.

I would get a real AC to DC charger.  If  IOTA isn't good enough, maybe
Magnum's is
ready or did I hear that the big  "X" has had one or two of these for quite
some time now ?

Power factor corrected even ?

The midnite classic 250 can do this fine. Rectify the generator 110vac to
around 165vdc and feed into classic. Use Aux functions to start and stop
generator based on battery voltage or SOC %.

Dear people:

 

I'm looking for an easy solution for battery charging off a generator, but
trying to save the cost of a big inverter.  I have a customer who needs to
charge a 48V battery bank with a 30A charger off of a generator--but I need
it to sense when the battery voltage is low, so that the "device" (charger)
will automatically turn on the (2-wire start) generator and charge the
batteries.  I am trying to avoid the cost of, say, a Magnum 4448PAE with its
AGS module, and just get a voltage sensitive battery charger.  Is this
doable?  Any ideas?

 

THANKS.
