Expanding on thoughts and trying to provide as much information as possible, 4 HV solar arrays create 2048 EU/t BUT the packets are still 512EU/t. So it's still only HV. Therefor you can use endless HV solar arrays directly into the MFSU without it blowing up through one glass fibre cable. I charged one MFSU with 64 HV solar arrays in about 20 seconds using only glass fibre cable between.

You can shoot EV to either 1 MFSU with a HV transformer in front of it or 4 MFSU's straight through the cable. As stated before you won't lose any energy either way.

So how do you know if you want HV Transformer + 1 MFSU or just 4 MFSU's? Simple. It all depends on the output. If you use 1 MFSU to convert the HV to EV again it will only send 2048EU/t packets as long as they are full, which means it has to wait for 4 512 EU/t packets before sending one bigger, this will result in a slower delivery of the power and you lose the whole point of EV. 4 MFSU's can deliver the full 2048 EU/t at full speed. The difference is that the MFSU will send 512 EU/t packets but 4 at a time since there are 4 sources while the HV transformer will send 2048 EU/t packets. This means that if you're using 4 MFSU you can power a machine with only 2 transformer upgrades.

Either way, transforming up to EV is basically useless since you can use HV for everything (including maxing out overclockers in machines).

I'm not absolutely sure about everything regarding EU since it's pretty confusing but I belive this is pretty much correct. My single player testing shows I'm right in practice, but maybe not in theory.
