Hi Jay....That is exactly how the system works. Output from the micros is variable up to 240Vac....At low power the voltage is down below a hundred Vac. I just installed a full power version at my house and am still assessing the efficiency. If they work as good as their marketing literature states then for a solar electrician like myself it will give me another tool to offer our customers. We don't do solar thermal because it is a different license and a different set if tools and parts and pieces to carry in the work truck. But solar heated hot water sure is great and this particular system type (PV) especially for all the reasons Dana mentioned. I will report back once I have had the time to asses it's effectiveness with my system. I am hopeful! Thought I would test it out on myself first. Cheers. Kirpal Khalsa
