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

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. jay peltz power On Dec 15, 2014, at 5:38 PM, Kirk Herander wrote: 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.

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. -- Thank you, Larry Crutcher Starlight Solar Power Systems _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
