The family and I are full time living in our RV. It has a small solar system, about 180 watts (2 panels), and a small bank of 8 batteries (the bank can hold upwards of 12 as designed). My problem is my charge control panel. Currently installed is a Solar Commander III. It has analog gauges, showing battery levels and solar panel output. I would like to upgrade this panel, as I am not certain how good it is or if it is really even worth keeping. It is mounted in a bulkhead, and the panel itself has all connections in the rear. It measures 5x7" approx and I would like any recommendations for replacements. Thanks in advance.
