The software in the newer SI operates in what could be described as an interesting way. The way to avoid the interesting operation is to only connect SMA gear to the battery.  If the SI cannot control all of the battery aspects it puts the off grid frequency to 60Hz when it detects a rising battery voltage. It thinks that the over voltage is coming from connected GTIs, so puts the frequency up to turn them off.
Iirc there are competitor SI products which merge the battery, pv, genny, grid etc.  I did look at the SI about 5 years ago, but the cost was too much.  It'll come down in due course.
