String Output

The Tigo products TS4-O, TS4-L, JES/HBF Smart Module junction boxes and 2ES add-on optimizers have a continuous output current rating of 12.5A, when used in a string application.

 

Being electronically-controlled devices, according to the National Electrical Code, the proper fusing for a single string is 15A (refer to the Smart Module's datasheet.)

 

The diagram below shows the optimizer's output curve during continuous operation in a string application. Maximum current depends on panel type, operating and environmental conditions.

Current can go up to anywhere between Isc and 12.5A
