Power Grids - Lancair style

[w1curtis]

Now that I've looked at the pictures, how do you isolate Bus A and Bus B? Also, how do you provent a device the "non-essential" Bus from draining the battery on the "essential" bus? I can't see that from the pictures.

Perhaps I didn't do this in the original email.

There are 3 grids in my setup.

Grid 1 - will go on the firewall (not in the pictures yet)
- very simple with 1 contactor (starter)
- 1 ANL for the primary Alt
- connector for interfacing to switching

Grid 2 - will go behind the seats on Main battery
- Main Battery contactor
- Avionics buss contactor
- ANL for avionics buss
- attach point to feed grid 3 cross tie
- ANL for primary buss
- connector for interfacing to switching and vreg

One note about this picture, there in an ANL that will be removed to connect the cross tie interconnect to the other grid

Grid 3 - will go behind the seats on backup battery
- Backup battery contactor
- Cross Tie contactor
- ANL for essential buss
- ANL for backup Alt
- connector for interfacing to switching and vreg


Combined, they make up exactly all the wiring and switching for an AeroElectric Z14 diagram with dual alt/batts
