Sofar Solar Tri 100 kW Grid Inverter – 100KTLX-G4

SOFAR 100 kVA solar inverter: Power and reliability for your PV installations

The SOFAR 75~136KTL is a transformerless PV inverter designed to convert direct current from solar panels into three-phase grid-compliant alternating current, thus supplying the public power grid. It is exclusively intended for use with PV systems in grid-connected conditions. Any other or additional use is strictly inadvisable, and SOFARSOLAR will not accept responsibility for any damage resulting from improper use.

Key functions
