I appoligise for not having a picture. The setup is HV solar array connected with glassfiber into input side of MFSU, this charges just fine, then glassfiber from outputside of MFSU into MV transformer input side, glassfiber go out of MV output side and connects to MFEs input side. The MFE fails to charge up. no redstone signals to the either the MV transformer or the MFSU. Just pure Power Gen, storage cables and transformers. I tried this on a test world and our server, tried with different levels of incoming power and cables. No recently placed transformers will work only the ones that have been down for a day or more. Server restarts dont help clearing cache didnt and trying different builds didn't. I know which sides are input and output but I did turn the units around even blowing up some just to test.
