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

quite some time now ?

Re: [RE-wrenches] AGS sensitive battery charger

2015-10-15 Thread 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

Exactly! And fully programmable voltage, charge timers, equalization, etc. I’ve 
been begging Magnum Energy to do this. About 4 years ago they started telling 
me they were working on it. I guess they don’t realize how many are needed. I 
sell lots of Iota because I can tweak the voltage but that’s still primitive 
compared to what is really needed.

Sorry boB, I retract my advice then :-)

Ive done it fine (I do like to use big filter caps on the input to clean up
ripple) and keep close tabs on whats going on.

My listeroid has been running into an MX60  for many years (7 or 8 years)
without issues at around 3kw into 48v bank, and has proved to be the most
reliable way to couple a generator that I know of (for what its worth).

Sorry boB, I retract my advice then :-)

Ive done it fine (I do like to use big filter caps on the input to 
clean up ripple) and keep close tabs on whats going on.


My listeroid has been running into an MX60  for many years (7 or 8 
years) without issues at around 3kw into 48v bank, and has proved to 
be the most reliable way to couple a generator that I know of (for 
what its worth).

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.
