Only some, few crimp connectors are manufacturer approved & agency listed for solid conductors.
Most crimp type connectors and terminations are rated for 19 strand only.
Check the package or TDS to be certain yours are rated for solid wire. Also use only those listed by an approved testing agency, such as UL, ETL and others. There are a lot of crimp connectors which aren't that for sale online at eBay, Temu, Bonanza, Walmart, Amazon, etc..
If you'd like the benefit of a crimped connector without searching for terminals and splices rated for solid conductors, Push-In connectors are an option. Waygo Wall Nuts are one brand. They also offer lever type.
Hope This Helps!
