Solar inverters and solar system management

Having installed over 100,000 units around Australia to date, we’re pretty familiar with the ins and outs of solar inverters and how they’re configured to meet your home energy needs.

What is a solar inverter?

An inverter is basically a box which takes the energy from your solar panels and turns it into energy your house can actually use.

Without a solar inverter, you wouldn’t be able to use the energy from the sun to power your fridge, television or air conditioning.

It’s one of the most sophisticated and important parts of your home solar system – and a nifty little piece of tech.

How does it work?

While solar panels will produce direct current (DC), your home and all the appliances within it uses alternating current (AC).

The solar inverter takes the direct current from your solar panels and turns it into an alternating current that your home can use as power.

So what’s the difference between the two energy types? A direct current basically runs in a straight line, whereas an alternating current looks more like a wave.

The solar inverter contains within it something called a “transformer” – which as its name suggests, transforms one thing into another.

How does it work in an energy system?

The solar panels collect the energy, and the inverter changes that energy into an energy form that can be used in your home. But that’s not all there is to a home solar system.

  1. Solar panels capture sunlight and convert it into direct current (DC).
  2. A solar inverter then converts direct current (DC) output from your solar panels into alternating current (AC) to power your appliances.
  3. If you install a solar battery, you can store unused energy generated by your solar panels for you to use when the sun isn’t shining.
  4. Any excess energy is pushed out to the grid. It’s measured and your feed-in tariff (FIT) is calculated and credited to your account.
  5. Your energy use and habits are easily tracked with a digital meter. You can keep track of your energy self-sufficiency through the Origin app.
Do I need one to feed energy to the grid?

Yes – the solar inverter is crucial to the process of feeding energy back to the grid, because it produces the same kind of alternate current the grid uses.

As we’ve touched on, solar panels produce direct current and in its pure form isn’t suitable for the grid. So, without the inverter you couldn’t feed energy back to the grid and earn feed-in tariff credit on your power bill.
