Watts needed
I have read where folks suggest any where from 1 to 2 watts of solar per ah of battery. My question, is this based on battery rating (ie 215 AH) or is it based on useable amp hours(105)? All reply...

Almost there? The Victron showed 923w output? But that has only 720w of panels.I guess I typed it wrong. The 923 was the total of both systems according to the Victron shunt
Where was that 714 watts at?The Victron controller
Controller output goes to load and remainder to battery. Any load is included in the controllers' output.
Can we get the output of the Victron only and compare that with the 720? I don't believe it can be 714 out of 720. No way. That is what it said. I took a screenshot of the screen.
One possibility is that the Aims panels are exceeding their specs. That could explain why they were too much for the Jaboni controller
See the voltage loss co-efficient per degree of C temp above 25C on your panel specs. Usually panel is about 20-25C above 25c ambient (50C when ambient is 25C is worth about a 10% loss in watts due to lower voltage--amps stay up despite the heat-even go a bit higher)
