Grid Voltage Drop - No solar power and errors

gbaig

I am using schenider xw6048 inverter and compatible charge controllers.  I am in Asia and we often have grid voltage drop from 220V to 200 or less during the daylight. In this case system stops producing solar power. The only solution that I know is to disconnect grid power. Does anyone have any other solution?

What is your desire?

Do you want the XW to continue to use AC grid power at 200 VAC? Or do you want it to switch over to battery power at that point?

Maybe a transformer that will provide a 8% boost and either switch it in or leave it in all the time (depending on what your max voltage is).
