I've got 6 siemens sr100 solar panels that I'm planning on putting on the roof of my mci9,,any input ,,advice on what mppt charger /controller to use..I have a 24v battery bank..thanks

Put your panels in series, make sure you use bypass diodes between panels...

I have a blue sky controller on six 80 watt panels and seems towork well. I see the voltage go up to about28.9 volts then drop back to float at 26.5 Jerry
Assuming 12V, nominal, panels?
Wire in series. Less current flow that way. Then use an MPPT controller from Outback, Blue Sky etc. I am familiar with the Outback MX60. Changes the voltage to as selected by user. The higher the voltage the better the MPPT controller works, efficiency.
I have 4 panels,180watts, at 24V nominal in series/parallel for controller input of 48V, as high as 65.4V. Maximum current I was noticed on the controller was 25.5 amps. That is close to theoretical maximum.
Make sure you get a remote display as you want the controller as close as possible to the battery bank.
That's a quick and dirty expose of solar controllers and panels.
Goggle Jack Mayer as he has a great website with a clear presentation of solar power and its pitfalls and advantages.
If i knew to import web addresses I'd provide the link.
