Nothing runs while I am not at the boat - only bilge.
At night, just the lights - not LEDS's ( damn they are expensive to replace ).
No refrigeration - ICE BOX!
Maybe the radio and VHF.
Dollar for dollar, switching to LEDs is probably cheaper than the larger panel needed to support non LEDs.
Here's what I'm using for my interior lights: LED Surface Mount Accent Light - iboats.com
At $14 per for the soft white ones, they were pretty cheap. I have 6 of those for daily use and then 1 white/red one on the nav table.
