How do you protect a solar inverter from a surge?

It’s crucial to protect not just the inverter, but other components like the solar panels and battery banks. Distance also matters. The farther your system’s components are from each other, the more likely they are to catch a surge. Surge protectors should be placed at both ends of any long wire run in your solar power system.

How do you size a solar surge protection device?

You size the surge protection device according to the voltage of your solar array, whether its wired in series or parallel.
