SunSpec model 128 Dynamic Reactive Current

SunSpec model 128 is the SunSpec information model for dynamic reactive current. It describes a group of registers. It is not a transport. Like other SunSpec models, it starts with a header that gives the model ID and its length. A device may support only some registers inside a model. There, ModEna at SunSpec register 40479 sets full or limited dynamic grid support. ArGraMod at 40476 sets the reactive current droop. BlkZnV at 40483 sets the PWM inverse voltage, with a default of 70 %. HysBlkZnV at 40484 sets the hysteresis voltage, with a default of 5 %. SMA SunSpec Modbus documentation says model 128 is no longer supported in SunSpec profile 2.0. Unlike several other old models, no replacement model is listed for it.

<!-- review notes

• sentence 1: support check: partial - Model 128 is named Dynamic Reactive Current and its registers appear, but the passages don't explicitly say it describes a group of registers or that it is not a transport.
• sentence 1: review: partial - The passages name model 128 as Dynamic Reactive Current and show registers assigned to it, but none says it describes a register group or that it is not a transport. -->
