They make AC and DC micro inverters, the DC ones are sometimes call optimizers. Their advantage is they you can have panels installed any place you like one panel being shaded or at another angle would not block current from other unshaded panels. The down side is higher up front cost.
You can have all the charge sources you want, but have only one setup to do the equalization charge, or buy charger from the same vendor that group charge.
Micro inverters? Sounds interesting. Would they all be in phase with each other, feeding an AC bus? I have never heard of that. What would be the advantage of that? I guess you would have a lot more flexibility in laying out the panels...
Also since I am using flooded cell lead acid batts, I would really like to be able to give them an equalizing charge once in a while, without resorting to shore power. Is this possible? That would be 62v for a 48v bank.
So generally, with modern controllers, the set points are user programmable?
