2.1. Product dimensions

SOFAR 1.1K~3KTL is a single MPPT grid-tied PV inverter which converts

the DC power generated by PV arrays into sine wave single-phase AC power and
feeds it to the public electrical grid, AC circuit breaker (refer to Section 4.4) and
DC switch used as disconnect device, and the disconnect device shall be easily
accessible.

Figure2-1 PV Grid-tied System

SOFAR 1.1K~3KTL inverters can only be used with photovoltaic modules
