Tigo TS4 Field Key
Certain modules (Tigo ready) come fitted with the Tigo Diode Cover as standard. The Diode Cover (White label) can be upgraded to an Optimiser Cover (Yellow label) and the tool to change the cover is called Tigo Field Key
Please note: before changing any covers, Tigo require installers and distributors to complete a short online course to ensure it is done correctly and safely. This only takes 5-10 minutes to complete and a certificate is issued at the end.
The Tigo course can be found HERE
