    What is the expected load for the shop , what is the size of the solar system. You are talking about an interactive solar system that connects to your line I hope.

  • How big is this shop, and is the welder the only major power-tool concern here? How big is the welder (I1eff/I1max from the nameplate) for that matter? Apr 6, 2020 at 23:04
