Growatt MOD 4000TL3 Inverter Outrange error!

Bought a Growatt MOD 4000TL3 inverter with Growatt batteries. When turning the inverter on I get an AC V Outrange (03) error. The grid voltage is 215v and the inverter is set to 230 volt by default? Thats why the inverter will not work i think. Is it possible to change the voltage in the inverter to 215v? I have the app installed, can i change the inverter voltage in the app settings and where exactly? I changed the grid parameters: High Grid Voltage Limit and Low Grid Voltage Limit. The changes are saved but it didn't fix the problem. I still have the outrange error. But for example when i try to change the working mode setting or the grid type setting i get a save failure, it doesn't save the changes. The password is correct.

Growatt Inverter and batteries are bought in the netherlands. But installed in the Caribbean thats where i live.

Thanks for the answers!
