Unless your invertors were set to operate at a slightly higher output
voltage. *Even just a few volts differential between the mains voltage
and the invertor output would mean that you could push current out into
the grid, and by doing that raise the local grid voltage slightly.-

This explains a lot about inverter technology, though not whether they
use a higher voltage, a leading phase angle or both to force power
into the line:
