I'm not saying it's not a good system but as a D.I.Y person, It certainly looked a lot more difficult to implement than the SMA.
The obvious problem with a LiFePo4 system and an A/C coupled set-up is getting the BMS to tell the master inverter to throttle back the slave(s). This is a plug-in option with the Sunny-Island. I'm not sure how it works with the Selectronic.
