Using (44) JASolar 370w panels in series and grid tied. The wire on panel is 12AWG - 2000V. Using 2 inverters with 4 strings and each having 410v and 10.3a. This system is an ungrounded system when using SMS 7.7-1SP-US41. Some of the strings will be extended to reach the inverters so I will have to make new connections.
Ordered a sample of 12AWG 600v PV 7 stranded wire. Wire is labeled as PV Wire or RHW-2 or USE-2. I know that in an ungrounded system you are only allowed to use PV wire. Am I safe using the listed wire. I attached the PDF of the wires available.
