For the detection of photovoltaic panels
Open the circuit breaker between the PV and the inverter and measure the DC voltage between (+) and (-) terminals of the PV string.
NOTE: The PV DC voltage and current must be within the range of the MPPT Input. Refer to product documentation.
NOTE: Keep in mind to take into account the difference between the open circuit voltage and nominal voltage of your PV array. If you’re measuring Voc that is slightly above the inverter’s minimum MPPT input voltage, it’s very likely that the Vmp voltage will be below minimum MPPT input voltage.
