At 240 Vac the 4.6 model is rated 4600 W and the 5.0 model 5000 W. The later manual lists maximum output of 3300 W for the 3.3 model and 4200 W for the 3.8 model. For communication it uses Modbus RTU with SunSpec and the Aurora Protocol. The -SB-RA model versions add a DC switch, a wiring box, arc fault detection and a supply output for rapid shutdown.

AFD listed for the -SB-RA model versions, which also include a DC switch, wiring box and RSD supply output.

c6 drafted · lead Constant power factor mode

Power factor above 0.995, adjustable to +/-0.8.

review note: support check: partial - The passage only gives PF >0.995 adj. ±0.8 for the 3.3/3.8 models, not 4.6/5.0, and doesn't explicitly say constant PF mode.
