[RE-wrenches] AGS sensitive battery charger

[Bruce Erickson]

Wouldn't the Atkinson GSCM generator start module do what you need? It can send start and stop signals based on voltage. I'm not sure if those are still being made.http://atkinsonelectronics.com/manufacturing/product_pdfs/GSCM.pdf

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.

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?
