January 7, 20197 yr HI ALL I HAVE 250 WATTS 12 SOLAR PANLES WHICH SOLAR PANELS SETTINGS IS BEST FOR INVERTER ? 12 PANELS SERIES OR 6+6 STRINGS ? THANX ADV

PV Array Open Circuit Voltage 250W panels have a Voc of about 38V so 12 of them in series will be about 456V. @mazo78 which brand 250W modules do you have? Or can you take a screenshot of the label at the back? @mazo78

Since their amperage ratings are slightly different, if you were to run two strings in parallel, the whole PV array would run at the lower amperage.
