This is the actual voltage of the circuit once a load (an appliance like a heater, phone charger, etc.) is connected to it. AC Volts is the voltage after an inverter has converted DC Volts to AC Volts. In various articles, solar panel output voltage refers to either nominal voltage, the open-circuit voltage at maximum power, or actual voltage.
Open circuit voltage (OCV) refers to the voltage that a solar panel produces when it is not connected to any load or circuit.
