What if update gone wrong, and display not working? What should we do next?

Hello, i have this Inverter in use, and i like to use Time-of-Use Mode, but do i see it correct, that even if i tell him not to charge during the day, if there is Solarpower from the roof available then he charges the battery anyway ? At least i have to assume this, as my Inverter exactly reacts like this. Thanks for feedback

Sofar 2200LT solar inverter में ओवर वोल्टेज का ट्रिपिंग आ रहा है. वास्तव में ओवर वोल्टेज है नहीं. इनवर्टर 260V को 280v दिखता है. और ट्रिपिंग अलार्म आ जाता है इनवर्टर बंद हो जाता है Any solution please..
