Tigo Energy, Inc.
Product: Tigo SMART Monitoring Website with Reclaimed Energy
Application: Residential, commercial, industrial, utility
Description: Tigo’s SMART website is a module-level online monitoring system that manages residential and C&I PV systems
with visibility into system analytics and tracks production, sends alerts, and suggests maintenance actions to keep systems operating efficiently. Tigo's SMART website can remotely power-off each module, eliminating high voltage for maintenance or safety issues. Tigo customers utilizing monitoring can also see
the Reclaimed Energy recovered by Tigo's TS4 optimizers - the amount of extra kilowatt hours that a PV system with TS4 has harvested. This feature is displayed with the Total Energy so system owners can calculate the ROI by year, month, day, hour, or minute.
