FAQs about Photovoltaic power automatic switching inverter
Do solar inverters need a transfer switch?
In some cases, the solar system does not connect to the grid. So the auto solar transfer switch must toggle the load between the PV system and a different source, such as a generator. But solar inverters usually come with built-in mechanisms to switch between power sources. So, where would you need the transfer switch?
What is a solar automatic transfer switch?
An automatic transfer switch, ATS, does that automatically, in your absence. Read more about the solar ATS below.
