I know with a piston the system is charged based on the superheat, and txv's with sub-cooling. How do you charge a system with a txv on the condenser and a piston in the evaporator?

That would be called a heat pump.
The TXV in the outdoor unit is bypassed, either externally or internally in teh cooling mode.
