Solar Inverter

KS 5 Series (3–5kW)

Overview

EFFEKTA KS 5 series solar inverters convert DC current from solar modules into AC current and feed it into the power grid. They feature a DC/DC converter with a maximum power point tracker (MPPT) on the input side and a single-phase inverter on the output side, synchronized with the grid. These inverters are available in models with either 1 MPP tracker (ST) or 2 MPP trackers (DT) and are ideal for private use.
