Victron MPPT Ground Question
Quick question about the ground connection on the Victron 100/20 MPPT charge controller. There are the obvious battery positive/negative and PV positive/negative connections. There is also what looks like a ground screw in the side of the charge controller. Is this ground connection necessary and if so can I just connect this to my battery/chassis ground? The attached picture shows the small silver screw in the side of the controller. The manual doesn't say anything about connecting this ground.
