I seem to be missing something important for setting up a near-Kerbol solar power array. I've tried a few configurations. The simplest was a Remote Guidance Unit, a pair of Gigantor solar arrays, and a Phased Array Transceiver (deployed). I activate the Gigantors and set the Transceiver to transmit in Ka Microwave.
The Gigantors show lots of flux, but the Transceiver shows no power draw or output.
The solar arrays are producing Electrical Charge and Megajoules, and other components can draw Electrical Charge, but do not draw Megajoules. This includes transceivers, probe cores, and capacitors.
