it is my understanding that the Sunny Island coupled with Sunny Boys is able to taper charge in an AC coupled system as the 2 inverters are able to communicate with each other and the Sunny Island alters the frequency input of the Sunny Boys and lowers the total output of the Sunny Boys to match the needs of the battery bank

Yes, if we use a Sunny Island AC coupled with a SunnyBoy we would not have the battery charging problem, but remember, the SunnyBoy is 240 VAC and the Sunny Island is 120VAC which I also find is just has expensive to match up by having to install an external step-down transformer so I still feel inverter manufacturers are missing an opportunity to provide a needed product feature that nobody is providing. .
