I think there might be some confusion on this thread. Yes I’ve done crimp battery lug connections for 30 yrs. I know many of mine are not UL listed for all sorts of reasons. I use the V crimp mechanical advantage style, not the sledge hammer type. And I’ve never had one fail. And they don’t require a ferrule. There are two types of battery cable termination at the inverter. 1: bolt connection which requires a cable and crimped on lug. Sol ark, midnite, outback etc. 2: a non bolt connection, now maybe I’m using the wrong terminology. I’m call it set screw like on my previous email link or some called a terminal block. This style the bare end of the cable is inserted into the terminal block connection. The set screw is then torqued down to the specified amount. This is the type that has two versions, 1 that is fine strand rated and 2 those that are not which require a ferrule. These inverters include LUX power and others. LUX power is who makes the EG4 and Fortress inverters. I hope this clears up any confusion. Jay On Sep 3, 2025, at 6:44 PM, Eric Smiley via RE-wrenches <[email protected]> wrote:
