Hello,
I'm looking for advice regarding my 1st set up, one 655W panel facing south, one 655W facing north, shallow roof pitch on my shed. https://www.bimblesolar.com/docs/Canadian-Solar-CSI-HiKu7_CS7N-MS_v1.6_EN_640-665.pdf

connected in series is over-panelled, yet NMOT is 489W, 35.6Vmp, 13.75A, 42.6Voc each. Do I understand correctly I might have a problem charging Bl AC200 max due to 35V battery charging requirement? I am not sure which third panel should I use to boost Voltage, if any.

Should I abandon the idea of 2 x 655W and choose 3 x 415W ? NMOT is 310W, 35.2Vmp, 8.81A, 42.4Voc each. https://www.bimblesolar.com/docs/CSI-Datasheet-HiKu_CS3N-MS_v2.6_EN_400-425-LM8-SOLAR.pdf I would have to make a stand for 3rd panel on the ground, maybe facing SE to get a boost from morning sun. no East direction available. My house casts shadow till about 10.30 am.

in south-east UK, no shade in the garden.
Your help is greatly appreciated.
