Ampster, everything you say is true. Its just an expensive solution to a rather simple problem (requiring very sophisticated hardware/firmware). What I was hoping to find was an Inverter/charger I could plug into my Main service panel, place a set of CTs on my Main feed and attach as big of an agnostic battery that I can afford. It would also be nice to be able to charge the batteries with a generator attached to the Inverter/charger with a auto start. My micro-inverters only generate a peak of 4.5 KW so I should only need a 4.5 KW inverter/charger. 4.5 KW chargers/inverters are only about $2500. For my application that is very cost justifiable.
The problem is the solutions I am coming up with using a SolArk and additional PVs is 4 or 5 times that. Yes, it offers a lot more but it is not as easy to cost justify. It will also need some "manual" intervention at points because of the generator/PV ac coupling issue.
