13.3.0 Electrical System

Next

I’ve started to work out the electrical system for the airplane. This is going to be interesting. I’ve decided to install a fully redundant electrical system using two batteries and two alternators. That should work out nicely since the Garmin G3X avionics system I’m planning on installing generally has dual power inputs for most of its modules. Therefore, the main distribution bus goes to the ‘A’ power inputs while the aux distribution bus goes to the ‘B’ power inputs.

Generally, both systems will run concurrently but I’ve added in the ability to cross connect the buses if needed. I’m also adding a shore power connector so that I can power everything up without running down the batteries while programming or troubleshooting the system. 

The schematic shown below is only the beginning of what promises to be many, many more single-line drawings.
