I'm contemplating doing 2s6p on a east west configuration ...my question is how to configure splitting the 12 panels 6 on each side ...?

I am not sure about your question? You will do 2s3p east and 2s3p west. What inverter will you be using? Single or dual SCC.

A Single input mppt ... planning on using 23 degree tilt east and west( our Lattitude puts us 13 degrees to the sun)... from using the panels (bifacial) as awnings at the end of the roof line (12 meters apart) to hopefully catch some reflection, 2s3p each side with 6mm solar cable ... combine three 32 amp dc circuit breakers for each of the three 2series positive cables on each array ...crimp three 6mm fly leads to a 10mm cable for positive and negative, and run the 10mm to a 2 pole DC 80amp circuit breaker.then into 10kw inverter ....I'm hoping this will work ...I know Il be throttling the inverter ...but it's the winter/ bad clouding days I'm aiming for...does this sound doable ?...we use about 5.7 kw breakfast and dinner times. Any suggestions you may have are warmly welcomed

Any suggestions you may have are warmly welcomed You will not be able to get 3x6mm² cables into a 10mm² without cutting some strands. Not good practise I guess. I would rather use a short copper busbar for such a joint.

Any suggestions you may have are warmly welcomed I would suggest to use mc4 3 way connectors then run single string east and west to combiner box less complicated. Use 6mm² solar cable to combiner and from there 10mm² from combiner to inverter. And use 1 x 20A inline fuse on each panel so you will need 12 fuses. Edited August 2, 20242 yr by TaliaB
