[RE-wrenches] Programmable Battery Charger

[Kirk Herander]

Thanks for the observation. I forgot it will rectify to the peak voltage.

Hi Kirk,

 

If you use a 200vdc midnight CC you'll have no issues.

When you rectify 120vac its up around 166vdc

( uses the peak vac which is around 170vac.)

 

For a 150vdc max controller ( midnite 150)  or a 144vdc ( outback FM) then a
buck transformer or standard transformer is the trick to reduce the AC and
hence the DC for these lower voltage units.

This has been discussed on this list in years past. It is possible to use an
outback charge controller as a battery charger. You need to put the 120 AC
into a bridge rectifier, then feed the 120 DC into the controller's PV
input. So you'll have an 80 amp battery charger.

You can manually adjust Iotas with tweaking the potentiomiters while
monitoring it with a god volt meter. But no time adjustment.

Wrenches,

Does anyone know of a 120/12 volt battery charger that can be programmed for
absorb and float voltage and time in absorb mode? I have been needing this
product for many years but I can only find it in inverters with built in
chargers from Magnum, Outback, and Xantrex.
