The document provides troubleshooting steps for the "AC V Outrange" fault on Growatt inverters. Possible causes include the grid voltage being out of range or incorrect voltage limits set on the inverter.
Hi @Cristian Orellana all your microinverters lost grid voltage on the 17th, it will either be a fault with a relay or a disconnected AC isolator. Suggest you contact your installer to inspect your system. Thanks TJ Roberts.
If the incoming voltage is low. Grid voltage fault occurs in the inverter when the AC voltage is out of range. In other words, when the solar inverter loses its connection with the grid, the voltage levels might be too high or low, or when the frequency deviates from the standard values of 50 or 60 Hz.
According to safety regulations, the grid-connected inverter must work within the specified grid voltage range, and can detect and synchronize with the grid voltage in real time. If the voltage value exceeds the safety regulations, the inverter must stop working and synchronize with the grid voltage.
