RV-14 pilot reported loss of all electrical power in flight resulting in landing at home airport with no ability to communicate with ATC.

Narrative

I lost all electrical power in my ASEL aircraft in flight. I was the sole occupant of the aircraft. This is an experimental amateur built airplane (built by me). The cause of the problem was that I had inadvertently left the alternators in the off position at the start of the flight. About 1.5 hours into the flight the Primary Flight Display (PFD); Multi-function Flight Display (MFD); radios; transponder and Autopilot all stopped working. The Garmin G5 backup attitude device continued to work as designed. I quickly identified the issue and turned the alternators on but because the airplane uses electronic circuit breakers for the electrical system; there was no field excitation for the alternators and they thus could not charge the battery.I was on an IFR flight plan but in excellent VMC conditions (though with very windy gusty condtions reported on METARS on my route) so I elected to continue to my destination. I had no reliable way to communicate with ATC so I continued on the routing that I had been given to the best of my ability. I did try to text my wife and another pilot to ask them to relay to ATC that I was OK and under control but had lost comms. My wife was able to do that.I considered the option to land at an airport along my route; but had very limited ability to find airports and get information on them (I was hand flying the airplane the entire time). I was concerned with landing at an unfamiliar field; with no (electric) flaps in gusty windy conditions. I decided it made sense to land at my home field because the wind was reported as directly down the runway and I was very familiar with that airport. I made a safe; successful landing without incident. In retrospect; I think this was the best option I had available.A few observations:1) An electrical malfunction in a modern technically complex airplane is VERY significant. You lose everything (power settings; fuel state; engine parameters; navigation resources; weather resources. Because I was alone in the airplane; I had to identify the problem; while flying the airplane and work out a strategy.2) Having an independent tool like Foreflight on my iPad was really helpful though a bit difficult to use while hand flying the airplane. Had I been in IMC; it would have been very difficult to navigate to an airport using the iPad while hand flying the airplane.3) While texting doesn't always work in an airplane; in this case it did. I recommend that there be a way to directly text the ATC system rather than use a best effort through my non-pilot wife.4) Being the builder of my airplane had helped me understand it's characteristics better than many pilots. Having said that; this was a serious learning opportunity for me.5) The G5 is a game changer. While it doesn't give you navigational capabilities; it gives you all the really important things like IAS; altitude; heading and attitude. The battery easily lasted two plus hours (and I suspect it would have lasted 4 to 5).6) Two issues I need to examine further: a. Why did the airplane's master caution light not come on when the voltage fell below a certain value? b. This airplane has e-magnetos which require current from the main bus to make them work. In the event of an electrical failure they have a small 'mini-alternator' on the e-mag that powers it. The problem is that if the engine RPMs are too low this mini-alternator will not supply enough power to the e-mags which can cause the engine to quit. I really need to understand this failure mode better.Second to the last topic: How did I forget to turn on the alternators prior to takeoff???I actually rigorously use a start-up checklist that specifically calls out turning on the alternators and checking that the system voltage is >14v. In this case I used that checklist and did turn them on at start-up. When there was a lengthy delay while waiting for my clearance; I shut the engine down. When I restarted after getting my clearance; I skipped thechecklist (stupid) and somehow didn't turn on the alternators. There is a lesson to be learned here.Last topic: I was very impressed by the ATC people. I spoke to them when I landed and found them to be professional; caring and very helpful.
