All Tigo EI Inverters consistently exceed 99% MPPT efficiency.
This includes:
- Tigo single-phase inverter models - TSI-3K1D, TSI-5K1D, and TSI-6K1D
- Tigo three-phase inverter models - TSI-6K3D, TSI-10K3D, and TSI-15K3D
The following static MPPT efficiency results are based on tests conducted using EI single- and three-phase inverters connected to two different PV modules at room temperature with a grid-connected voltage of 230V, 50Hz.
