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.

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. --Chris @ the Oasis MT _____ From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of b...@midnitesolar.com Sent: Thursday, October 15, 2015 5:29 PM To: i...@windsine.org; RE-wrenches Subject: Re: [RE-wrenches] AGS sensitive battery charger 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 ? boB On 10/15/2015 4:20 PM, Roy Rakobitsch wrote: The midnite classic 250 can do this fine. Rectify the generator 110vac to around 165vdc and feed into classic.

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.
