That's no problem, off course you want to configure as high as possible in voltage (without going over the limit of the MPPT)

The 17 Enphase grid inverters will actually raise the AC voltage by 14V at full power on their side of the 200m AC cable. If your Easysolar AC output voltage is 230V and you add 14V you will have 244V at the Enphase inverters. It depends then on the configuration of the Enphase inverters (the country setting) when they disconnect themselves because of high AC voltage of the grid.

I don´t know if those 17 Enphase inverters synchronize when they disconnect at high AC voltage and shut off all together. That might cause some instability in your system if their full power suddenly is missing.

In case each Enphase decides on its own AC voltage measurement to disconnect, it should be a minor problem, because the 17 inverters will have small AC voltage measurement differences, and after one Enphase inverter disconnects, the voltage will drop and the others keep running (till the next one might drop off etc).

In case you see that the Enphase inverters turn off because of high AC voltage, you might reduce a little the Easysolar AC output voltage, or raise the AC high disconnect voltage in the Enphase inverters if you have access to that setting. Or increase the AC cabling.
