Dear Matronics Society!
First - I am extremely happy to meet all of you.
Guys, hope for your kind help in this complicated task.
GENERAL CONFIG: IFR flights
Power sources config:
1 - alternator 60 A with internal voltage regulator (Plane Power AL12-EI60 (99-1012))
2 main battery 24 Ah (Concorde RG-25XC)
3 backup smart battery (TCW IBBS-12V-6AH) max cont load 8 A, intermittent 12
A
Engine: Lycoming IO-540-D4A5
Ignition: standard Champion SLICK MAGNETOs 6393 (LH) and 6350(RH) plus SlickStart
module S1001 for one magneto(left) for better start. Keyed ignition switch
ACS A-510-2K.
Avionics Dynon SkyView HDX complex with 2 monitors (+2 backup batteries for displays)
and respective subsystems, except comm.
Communication Garmin GMA245 with GTR 225A
Backup navigation - Garmin G5 system (+ backup battery).
I am looking for reliable and simple enough system
Bob was extremely kind to me and helped with initial idea of Primary Electric system
for RV-10.
Wiring: https://drive.google.com/file/d/1lbioIrf2NMAUnkgLyg7kzthyvVueMHyV/view?usp=sharing
I have done ELA but found that with 60A alternator i have load that exceeds alt
capacity (about 65 A total current draw in max config, that is practically unrealistic
situation, but ...). So, now i will double-check ELA, and then will
think what to do...
Here is ELA with power sources assessment and List of equipment:
https://drive.google.com/file/d/1lbioIrf2NMAUnkgLyg7kzthyvVueMHyV/view?usp=sharing
Regarding aux battery - we will use TCW IBBS-12V-6Ah, that can continuously supply
8 Amps when sensing main bus (or another bus, depending on Primary elec system
logic) voltage drop below 11 VDC.
My idea was to create Essential bus to power from this TCW backup battery in case
of emergency.
Quote from TCW Tech Support letter regarding backup battery:
The pass-thru pins are an input that you connect to the main bus. They bring power
into the IBBS which is automatically passed through to the outputs. During
normal operation, the power from the aircraft bus comes into pins 6,7,8 and is
passed out to pins 12-15, this allows the equipment connected to pins 12-15
operate normally. Then if there is a condition on the main bus where the voltage
falls below 11 volts, the IBBD internal battery is connected to pins 12-15
to run the essential equipment. No power is back fed to the main bus.
If someone has experience in such smart battery utilization - please, share, its
very interesting
I am kindly asking for help and any kind of assistance and guidance for Primary
Electrical System architecture calculations and building. Without you at this
stage I do not see the way to successfully build RV10..

Most of the users weren't able to find the right solution to perform Office
365 to Office 365/Live Exchange server. EdbMails Office 365 migration tool is
the one whic provides the smoothest experience to the end users. All your mailboxes
will be migrated to the target server without any hassle.
Few highlights of the software:
Secure and Safe migration
Security is the most complex thing during the migration process. EdbMails software
provides the full security for the data during migration and migrates the
complete data to the target server without any modification in the source data
by maintaining the original source folder structure intact. There is no size
limitation for the mailbox, you can migrate large mailboxes safely to your target
server.
Batch or Individual migration
Office 365 migration supports the individual as well as batch wise mailbox migration.
No need to migrate entire mailbox data. You can migrate specific data to
the target server using filters.
Easy handling of Office 365 throttling
EdbMails Office 365 migration easily handles the Office 365 throttling and connection
interruption during migration.
Incremental Office 365 Migration
EdbMails Office 365 migration supports incremental migration. With this feature
you can migrate only newly created items to the target server during consecutive
migrations on the same system and avoid duplicate items migration on the target
server.

absolutely worst case, in that list (unless that Dynon stuff is hideously
inefficient). Have you done a spreadsheet, or even just a list, with every
load item with columns showing continuous and peak loads for each device,
and if applicable, an intermittent duty column? For example, the
Slickstart, and flaps, would be intermittent duty, & need not be part of
the continuous load calcs. Comm would have some very low consumption
(likely under an amp) except when transmitting. etc etc
Be aware that many (most?) devices spec a circuit protection device that's
a lot larger than continuous draw, and somewhat larger than even peak
inrush current. In some cases, you might need to actually power up the
device to determine its actual continuous & peak draw; some mfgrs don't
bother to include that data.

Mmm not sure....before there was no crackle with the audio and the audio
system is unchanged.
The plane is composite and the jacks are isolated. But ill check that.
Its an easy task.

Thank you, Chris, those wiring schemes are great, but unfortunately they use plenty
of some Power Circuit Boards (perheps supplied by VANS with kits).. but plan
to use some elemets in avionics hookup

Charlie, I have made separate ELA doc, perheps it is some problems with viewing.
now it has 2 main columns - "Typical" and "Max" load. PLease, have a quick look:

With that engine, why are you including a backup
battery? A 8-10A standby alternator on a vacuum
pump pad offers UNLIMITED endurance with about
a 4 pound penalty. I go out of my way to avoid
adding batteries to a design over and above
those normally expected to start engines and
back up the primary alternator.
Do you not PLAN to conduct periodic airworthiness
checks on the main battery?
