Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

De Aar Solar Power is located 6 km outside the town of De Aar in the Northern Cape Province of South Africa. The facility is based on over 100 hectares of Emathanjeni Municipal land, and comprises 167,580 solar (PV) panels .
Following the Class 9E in 1978 and the Class 7E1 in 1980, the Class 11E was the third single-cab mainline electric locomotive to be acquired by the SAR. Until the Class 9E was introduced all South African mainline electric locomotives were dual cab units, but since the Classes 9E, 7E1 and 11E locomotives were designed to be used in a service where multiple unit operation was the normal ...
