Learn why your Tigo TS4-A-O is showing 'Not Found' during scans and how to fix it.
The 'Not Found' message indicates that the optimizer is not communicating with the system. This could be due to a connection issue or a malfunction.
Check all connections and ensure the optimizer is powered. If the issue persists, consider resetting the device or consulting the manual for further guidance.
The "Not Found" status generally indicates a loss of communication between the optimizer and the inverter. This can occur due to various electrical issues such as improper RISO (Insulation Resistance) measurements, which may trigger ground fault detection, or if the optimizer operates outside the acceptable grid frequency limits. The inverter relies on feedback from the optimizers to manage power output and ensure safety protocols are adhered to, thus a fault in communication can halt operation.
During a system scan, the Tigo TS4-A-O may display a "Not Found" status, which can be indicated by an alert on the monitoring app or a lack of data from that specific string. The LED indicator on the optimizer may not light up, or it may blink in a pattern indicating a fault. Users may also notice a drop in production metrics from the affected string, leading to lower overall system performance.
Always ensure that a licensed electrician or certified solar installer performs any troubleshooting or repairs to maintain safety and compliance with electrical codes.
To avoid future occurrences of the "Not Found" status, regularly inspect and maintain wiring connections, ensure firmware updates are applied to both the inverter and optimizers, and perform routine checks of the system's insulation resistance. Additionally, monitoring environmental conditions that could lead to overvoltage or undervoltage is crucial.
