Are there some special requirements if I want to parallel multiple Smart G2 inverters?

All inverters are recommended to be of the same series and All inverters should be of the same software version.
When multiple inverters are to be connected in parallel on three-phase grid, it is recommended that the inverters be connected on different phases so that the power
on different phases is distributed more evenly.
We recommend that for a system with multiple inverters connected in parallel, connect the ground points of all inverters to ensure equipotential connections to
ground cables.
