Product dimensions

1.1K~3.3KTL-G3 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

1.1K~3.3KTL-G3 inverters can only be used with photovoltaic modules that

do not require one of the poles to be grounded. The operating current during normal
