There are a lot of foreign readers here. I figure its a place to ask. Anyone see any good brands of voltage regulators that can take solar power and regulate it directly into a car battery. In the US, everyone wants to sell you a grid tied system. I don't want all the complexities and infrastructure. I want a few panels and a charger that can sense the grid output and car battery needs, then regulate the charge. So far I have seen one product from Australia.
