That's because you don't have enough Plasma Generators. I'm running your set-up with 43 Plasma Generators (18 for the machines, 1 for the Matter Fabricator and 24 for the Fusion Reactor which are connected to the Energy Injectors by 4x insulated HV Cable. Supplies more then enough power to everything and it's "Set and Forget". You have to have 16 Injectors for the Reactor to get fully charged.
No, I got it working. 8 energy injectors (I only need 6 to be able to use all recipes, but I want a bit of spare power just in case) 10 plasma generators (which leaves a ton of extra plasma in case you need more power) 32 electrolyzers fed by 20 aqueous accumulators with transformer upgrades - all the way to EV. The electrolyzers are each connected to their own AESU at max output. 18 centrifuges with 3 over lockers and 2 red, 1 blue transformer upgrade each. 3 are for deuterium to tritium, 15 for hydrogen to deuterium. One AESU for every 5 centrifuges works, the deuterium to tritium ones are on one line. I had to hook up a small redpower system to, every minute or so, switch between sending deuterium to the tank for the reactor or to the centrifuges for tritium, otherwise I would get a buildup of either deuterium or tritium, and barely enough of the other.
Summary:
20 aqueous accumulators feeding 32 electrolyzers. (1 red 1 blue transformer upgrade) 1 AESU at max power for every 10-11 electrolyzers.
15 centrifuges for hydrogen to deuterium. (3 OC's, 2 red, 1 blue transformer each) 1 AESU at max power for every 5 centrifuges.
3 centrifuges for deuterium to tritium. (Same upgrades as above) 1 AESU at max power. Note: Unless you add a balancer to stop producing tritium for a period, and send all deuterium to the reactor, you will get extra tritium and not enough/barely enough deuterium to run.
Self-sufficiency achieved.
