I've got a 9100 manual and it is MAINS first for initial power up. From that point on it is BATTERY first.
And yes I've fitted many - mainly about 20 years ago.
If the manual is wrong - why have they never changed that info?
Contact Scantronic if you wish.
joe, I aint interested in arguing the point with you beyond this - the manual doesnt deal with locked panels, most manuals say battery first - so out in the field you can stand there powering up battery first all you want then when you can`t get it running take it back?
MAINS FIRST EVERYTIME
Quick test for you tommorow - power a panel up (new) battery first and test the volts / current compared to minimum values.
