Inverters

Sort by:
Filter

Inverters change DC current from batteries or solar panels to 220V 50Hz alternating current (AC) as needed for appliances. The generated AC output is in a pure sine wave form that is identical to the grid AC. 

The Axpert-type inverters are considered to be hybrid inverters because they can charge batteries from the grid (Eskom) and from solar panels.
