Nomura MPPTs have not been working, so an alternative is being investigated.
They basically sold us an IC with its application circuit on the board, so creating our own custom MPPTs is more desirable.
On solar sense, there is an MPPT_Interface schematic sheet. I think it would make sense to move all components on that sheet to the MPPTs (although the buffer could be removed if the ADC is on the MPPT).
