I upgraded the converter to a PD 4655 and also upgraded the charging wire to the batteries to #2 (#4 in parallel with factory #6) so it's pretty efficient now. Really just looking for something to keep the batteries charged while the TT is in storage and maybe offset some light use during boondocking. I have a Honda 2000 that I use for battery charging while boondocking so I don't need the solar to carry all of the usage.
Let's say I watch the late show and the batteries are at 75% when I turn off the TV. The sun comes out and the solar controller is sending 14.4v to the batteries. When I roll out of bed and fire up the Honda, the PD4655 will start putting out 14.4v to the batteries. Does the solar controller stay online so its amperage will contribute to charge the batteries faster?
