SMA will sell a SB4000US programmed to limit the AC output current to 16.0A. I think they designate it as a SB4000US-CL, or something to that effect.
Interestingly enough SunPower, which rebrands many of the SB inverters (including the SB4000US) and sells them as SP products, has chosen not to support this specific product, nor have they given any indication that they are studying the situation with the goal of supporting the product through their channel in the future. - Peter Peter T.

But a SB4000 requires a 25A breaker which violates the 120% rule with the existing panel. Comments on the options below. #1) Go with another 240v grid tie inverter in the 3800W range, so we can use a 20 Amp breaker. I see PV Powered and Kaco have 3500s listed. Any 3.7, or 3.8kW inverters? #2) Is it possible to either, change out the Main Breaker in the above GE load center to a lower amperage MB, or add a Plug In Breaker. There is a GE feeder type breaker # THQL2190 (90 A DP). Could we use this as the main breaker for the load center above? It is listed as a 10KAIC breaker. #3) Swap out existing 32 space load center and replace with 150AML panel with 100A MB kit.
