Confirm PV CT direction reversal

The prototype PV generation arrow defaults away from the PV inverter and toward the PV board. Reversing it toward the PV inverter may reverse the measured generation direction. Check the exact inverter manufacturer’s CT polarity and commissioning instructions before installation; polarity conventions vary by manufacturer.

Built around the measurement, not extra hardware.

The utility meter records billing energy. The selected grid measurement supplies control information.
