Solar inverter KS 5 series 3–5 kW




As part of your photovoltaic system, EFFEKTA KS 5 solar inverters convert DC current directly from solar modules into AC current and feed it into the power grid. On the input side there is usually a DC/DC converter with a maximum power point tracker (MPPT) that feeds the intermediate circuit. On the output side there is a single-phase inverter, which feeds into the power grid and is automatically synchronized with the grid. The KS 5 series solar inverters with an output power of 3,000 to 5,000 watts are ideal for private use. The inverters are available as models with 1 MPP tracker (ST) or 2 MPP trackers (DT).
