Grid tie inverter australia

What is a grid tie inverter?

Properly configured, a grid tie inverter enables a home owner to use an alternative power generation system like solar or wind power without extensive rewiring and without batteries. If the alternative power being produced is insufficient, the deficit will be sourced from the electricity grid.

Do solar panels need a grid tie inverter?

Grid connected solar systems need grid tie inverters. These are special solar inverters that will synchronise with the electricity grid. They produce grid compatible 240V AC (sinewave) electricity from the DC voltage that your panels produce. The electricity from a grid tie inverter is indistinguishable from the grid's electricity.

How to choose a good cable size for a grid tie inverter?

The thicker the cable, the lower the resistance, and the lower the power losses. If your grid tie inverter is more than a few meters away from your electricity meter, then insist on a cable size that reduces power losses in the AC cable to less than 1%.

What is a grid connect inverter?

A high-quality modern grid connect inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1 degree of the AC power grid. The inverter has an on-board computer which will sense the current AC grid waveform, and output a voltage to correspond with the grid.
