#1 -  Renewable Energy > Technical Discussion: Solar Electric System - Photovoltaic > 48v battery bank charged by 12 v panel controller
hey Everyone, obvious Newbie here.
I have 4 Kyocera 400 w panel system, still in the box.
I also have 4 Deka 92AH 12v AGM batteries, that are supposed to be hooked up to a cotec S1500 48v inverter.
The charge controller that I have is a Sunsaver Duo controller, that is supposed to be able to charge two separate battery banks in the same time.
The limitation is 12 v input on the controller, however I have two of the controllers, so theoretically I could charge all four batteries individually.
My question is:
Can I charge the 48 v battery bank (if I hook it up in series), with the  Sunsaver duo (12v) charge controllers??
I have double (post and screw type stud) terminals on the batteries, so I am thinking I could use the posts to get the series hook up and in the same time I could set up individual 12v charging coming from the controller on the screw type studs.

I got the obvious answer, get a 48 v controller, however my geographical location makes it difficult to get parts, such as that, so I am keeping that as my last resort.

Any input I most welcome.
