I am not sure why you would want a 36 volt inverter. This is not a standard setup at all. I have several hi capacity 24 volt banks of batteries and use one Classic 150 charge controller on each bank. One charge controller is fed with an array of 72 cell "24" volt panels which have a MPP of 36 volts. These are wired 2S6P , a series connection that produces about 72 volts at MPP. The classic converts this 72 volts down to the 24 to 30 volts needed to charge the battery. The other nearly identical system has 96 cell 53.5 volt @MPP Sanyo HIT multilayer panels wired as all parallel. 12P . Again the Classic converts this 53.5 volts down to the 24-30 volts needed to properly charge this battery bank.
If if you will notice......The array output voltage is >two times battery voltage......this is what is required to properly charge a FLA battery set with an MPPT....(Maximum Power Point Tracking) controller
Also please note.......The batteries are NOT IN PARALLEL.......they are separate systems that can be paralled but are kept separate as parallel sets of batteries are problematic. I have 100% redundancy in a super reliable system....no fails, no brownouts, no system shutdowns , I have never had a LVCO (low voltage cut off) where the system shuts down cold due to discharged batteries. I have no utilities at all and do depend on my systems being super reliable as I use some power medically which is totally out of the scope of this forum.
Please note......I am not here to criticize how someone else does things......I share my expereince doing what has been proven to work. If you disagree with me, then that's fine, I won't argue the issue. There are things that you have done that I would not do in any case.
My background......born in the backwoods of Alaska, learned how to do with very little back in the 50's, a born off gridder...LOL I'm off grid because I know that I can do it!
My suggestion for you...Get a decent charge controller and inverter, do a 24 or 48 volt system, keep it standard and listen very well to the good advise and you will get good help, ......be argumentative and folks will avoid you.....don't take that personally!...no really do take that personally........I don't mean that offensively.....
