The Sunny Boy TL-US-22 is a family of SMA Sunny Boy string inverters for the US market. SMA lists the manuals for this family with its current Sunny Boy documents, not in the archive for older inverters, and they can be downloaded from the SMA download area. The evidence gives no electrical ratings, supported functions, protocols or certifications for this family, so check the product manual for them.
