Tigo DUO Retrofit Frame Mounted Optimiser TS4-A-O-Duo


Compatible with Tigo TS4-A-O single input optimisers*

The TS4-A-O-Duo is an add-on or retrofit solution that brings smart module functionality to standard PV modules, adds smart features to new PV installations, or upgrades under-performing systems. The Duo cover with UHD-Core technology and expanded specifications supports two PV modules connected in series with a combined power of up to 700W. 

This revolutionary optimiser from Tigo works with any panel and any inverter. You you can use as few as one optimiser on a system - ideal if you have a couple of shaded panels or on another orientation. Only those panels that are shaded, or those on a separate roof, need to be optimised and can be mixed in a string with non-optimised panels.

The TS4-A-O-Duo clips tightly onto the frame of the module and connects using MC4s.

Key specifications

  • Rated DC Input Power: 700W
  • Maximum Input Voltage: 90V
  • Maximum Continuous Input Current (IMAX): 12A
  • Weight: 0.56Kg

* If installing monitoring with a mix of singles and duos then you will need to email Tigo customer support to let them know to adjust the monitoring.
