In a system with 14 panels facing south with optimisers we have 3 that are in the shadow of the house in the morning. I would expect that the optimisers would ''bypass'' those 3 by bucking the voltage and increasing the current and give full performance to the other 11. That does not seem to happen. Around 11.00 o'clock also the 3 panels are in the sun and you see the current jumping up as expected. Can you explain why the optimisers behave like this?
See attached picture.
Thank you for helping
