...Another option is to have a DC-coupled battery, like @Reed_Richards does. Any excess over 3.68kW can be diverted to charge the battery, then allowed out again when the solar output falls. (I don't know exactly how RR's system works but its's something like that.)

At 12:20 yesterday my PVs were reportedly producing 3.96 kW and my battery was supplying 1.75 kW all of which (and more) was going to domestic consumption. Obviously 3.96 is not that much greater than 3.68 but there is nothing in the report to indicate that any power was being lost. "Export power limitation" is a numerical setting for the inverter; I don't know how it is achieved but the inverter monitors import and export.
