What is a Transformerless (TL) inverter?

The difference between standard or conventional inverters and transformerless inverters are:

  1. Conventional inverters are built with an internal transformer that synchronises the DC voltage with the AC output.
  2. Transformerless (TL) inverters use a computerised multi-step process and electronic components to convert DC to high frequency AC, back to DC, and ultimately to standard-frequency AC.
Benefits of Transformerless (TL)Inverter Appeal

Transformerless inverters are light, compact, and relatively inexpensive. Since transformerless inverters use electronic switching rather than mechanical switching the amount of heat and humidity produced by standard inverters is greatly reduced.
TL inverters maintain the unique ability to utilize two power point trackers that allow installations to be treated as separate Solar PV Systems. In other words with TL inverters, Solar PV Panels can be installed in two different directions (i.e. north and west) on the same rooftop and generate DC output at separate peak hours with optimal effects. Traditional inverters work through only one power point, which means panels that are performing at lower frequencies will lower DC output for the entire system

What is A Solar Grid-Tied Inverter?

A grid tied solar system turns sunlight into electricity by using solar panels and a power inverter.  This all happens while your home or business remains connected to your  local electricity grid.

Why install a solar Grid-Tied Inverter System?

People install solar grid-tied inverter system is to save money on electrical bills, improve their carbon footprint and reduce reliance on the aging grid network.  While still having to use the grid when needed.  By using as much solar energy  in the home as possible, you can certainly reduce your power bills, and by transferring excess energy from your home to the grid, you are actually contributing to a cleaner more sustainable energy network in NZ.  By reducing the need to draw electricity from distant Dams to your home, & even more importantly reducing the countries need utilise the Huntly coal station.

How does a Grid-Tied Inverter System Work?

The solar panels that you install are the first step in having a successful solar Grid-Tied Inverter system.  These solar panels collect the sunlight that shines on them and produces a direct current (DC).  Now this DC needs to be converted into alternating current (AC) in order for your home to use this electricity.  This conversion happens through the power inverter that you have installed.  Once the DC is Converted into AC by the power inverter, you are able to use this electricity.  This process is simple, fast, and efficient.

The great thing about the Grid-Tied Inverter system is the ability to send any extra power generated back to the grid, which means not only can you make some additional savings (depending on you electricity provider), your neighbours can then use the clean efficient solar power you have produced, rather than drawing electricity from remote Dams or even worse from Huntley coal station.  Again this all happens quietly and automatically.  Easy, Clean, Efficient Electricity at your place!
