FAQs about Isolated vs Non-Isolated Photovoltaic Inverters
What is the difference between an isolated and a non-isolated converter?
In an isolated converter, the input and output stage have separate grounds whereas in a non-isolated converter, current is able to flow directly between the two sides as they share a common ground.
