Note - each of the original incandescent interior cabin lights draw about 1 Amp. I replaced all of them with LEDs, and the total is 2.5 Amps! Likewise for the navigation lights. I have not replaced the anchor-light, but that's next on my list!
It is interesting that even with 300 AmpHour house battery bank, I only have enough capacity to keep the boat's electrical usage for 24 hours. On multiday sailing, we need to charge the house battery bank every day.

Likewise I've replaced all lights w/ LEDs except the anchor light.
ReplyDeleteLet me know when you tackle that, I can help and between the two of us we can eliminate 1 climb up the mask. ..unless you know what kind of bulb is up there..
The Masthead light is 12V/5W Halogen 904003884.
ReplyDeleteAs for the table of power consumption above, the Macerator Pump, Windless, and Microwave are all incorrect. Probably 10% of what is stated is correct. (Move the decimal place 1 position to the left.)
