Data is only transferred if I-V curve data is present. Check that tests on the PV200/210 have been carried out in either Mode 2 or 3. If this is the case, then check the Android device settings menu that “Android Beam” or “S-Beam” (depending on Android device model) is turned OFF to aid communication accuracy. Receiving device must be held very still against the NFC symbol on the front of the PV200/210, at the same location as the NFC antennae on the Android device – check device owners manual for location of the NFC chip. If data cannot be transferred, check the data can be downloaded to SolarCerts and examine this closely for any corrupt tests. Corrupted data can prevent data transfer to the app. If all appears as it should, have the NFC function checked by Seaward.
