About Solar PV Inverters

Solar inverters, also called grid-tied inverters, convert the direct current (DC) electricity produced by your solar PV panels to alternating current (AC) electricity that can be used in your home and exported back to the grid.

  • ensure compliance with regulations about feeding electricity into the grid, for example by immediately disconnecting if there is a power cut
  • maximise electricity production by constantly varying its resistance (load).

Solar inverters are very efficient, usually 93–96% depending on the make and model – never 100% because they use some of the input DC power to run, generally around 10-25W. Their efficiency can be improved by an electronic technique known as Maximum Power Point Tracking (MPPT). The point of maximum power output of a solar PV cell is dictated by a combination of current or voltage. Where it is will vary constantly according to light levels, shading, temperature and the characteristics of the solar PV panel. A MPPT system continually searches for this point to extract the maximum power available from the cell. Multiple MPPT systems can maximise yield even if part of the array is shaded.

A solar inverter is a critical component for a photovoltaic system, they play a role in any solar energy system, whether it’s a 2.kw residential system or a 5 mega watt power plant, you will need a solar inverter.

An inverter’s basic role is to “invert” the current (DC) output of the photovoltaic system into an alternating (AC) current. The AC current is what is used by all domestic & commercial appliances. Many people call a Solar inverter, a “Gateway” as really, it is the path between the solar pv system and the energy distributed to your appliances.
