Inverter

Code	Meaning	Severity
03X9A	The inverter cannot communicate with the SolarEdge monitoring server, or there is a communication fault between the inverter and its power optimizers. moderate	moderate
03X9B	One or more power optimizers on the solar panels have lost communication with the inverter. The affected optimizers are not reporting data. moderate	moderate
18XB5	The inverter has detected an internal hardware failure, most commonly in the power conversion board or a critical internal component. high	high
18XB7	The AC grid relay or contactor inside the inverter failed to close or open correctly during the grid connection sequence. high	high
18XF5	The inverter has detected that DC current is being injected into the AC grid above the allowed limit. This is a grid protection fault that prevents DC contamination of the AC network. high	high
2XB	The AC grid frequency has deviated outside the acceptable range (typically 47-52 Hz for 50 Hz grids or 57-62 Hz for 60 Hz grids). The inverter disconnected from the grid as required by safety and utility regulations. moderate	moderate
3X2	The AC grid voltage at the inverter connection point has exceeded or fallen below the acceptable range. The inverter has disconnected from the grid as required by safety and utility interconnect standards. moderate	moderate
