I was hoping to connect the two 24v panels in series into a TS-MPPT-45 solar charger from morningstar with battery temperature senor. This I believe would only sense the entire 48v bank. To charge the bank from the Honda 2000 the elcon 1500 charger could be used as mentioned in a previous post. The existing sea ranger charger would have to charge the separate house bank. Since the batteries I am charging are 6volt x 8 going to a dual pro quad charger would monitor and charge two batteries from one lead. Is there another solution for individually charging and monitoring each 6volt battery. Thanks for the heads up Eric.

Though I question how you plan to charge the 48 volt bank with the currently installed 12 volt charger. Also are you going to put the two 24 volt solar panels in series to make the 48 volts?

Could this be used as a bulk charger from a Honda 2000 generator and a separate 48v smart solar controller. I was planning on purchasing two 175 watt 24v solar panels with a later addition of a wind generator.
