TS4 with Solectria Inverters

Using TS4 with Solectria Dual MPPT Residential Inverters

Solectria residential inverters include an MPPT shading function. Tigo products perform best when this function is disabled, particularly in systems equipped TS4-O and -L.

In order to disable the MPPT shading function, follow the below instructions on the inverter:

1. Go to "Option" and then to "Shading (MPPT1)"
• Press enter until the inverter display reads "Disabled"
2. Go to "Option" and then to "Shading (MPPT2)"
• Press enter until the inverter display reads "Disabled"

These instructions can also be found in the Solectria installation and operations manual, available here.
