Hi,
Following from a discussion on the email list, I thought I would post the upgrade I made to my electrical system, to monitor the battery usage (or more accurately the power usage).
I installed a BMS-001, which monitors the house batteries. It comes in handy to watch what some devices draw, and gives you a "Fuel Guage" type approach on how much capacity your batteries still have.
This was very easy to install, and for the last two years, has worked well.
Note - The unit was re-positioned to make way for the autopilot control.

Thanks for posting, Rockman. I agree that accurately monitoring your battery state and energy in/out is important.

Curious as to how well that tank monitor worked out for you (the one I see in the photo)? I installed the same one last off-season, and I've had great difficultly getting it to read properly...

Ah, the tank monitor.
The fresh water tanks seem to work ok. When they are full, the monitor says full. When empty, it reports empy.
But, the black water tank (from the toilet), is a little more fickle. It takes a while for the monitor to report anything in the tank. Then all of a sudden it will report 40%.
As the tank is easy to access, I check the levels by tapping the side of the tank.
I did test the monitor by filling the tank up with water, but it did not report anything in the tank - maybe it was looking for some thicker water.
