A solar inverter is the brain and the muscle of a solar power system. Discover what you should know about the selection of one in 2025.
When choosing the right solar collectors, it is even more important to select the right inverter. Save your choice and you could step on the track.
The role of an inverter
A solar inverter decreases the high -current voltage (DC) from its solar collectors, which can be up to 1,000 volts (V) -and transforms it into 230 V change (AC), suitable for use by home devices and for export into the grille.
With the settings for installation producers and built-in smarts, this device also ensures that local power grid rules in relation to the export of electricity into the network are determined at a certain point in time. And stops exports when the grid throws a wobbum – for example during a blackout.
Solar inverter with various other devices such as hot water systems, house batteries and chargers for electric vehicles with various other devices must be communicated to an increasing extent. Minimize your expensive power power current consumption by fully exploiting the excess self -generated solar energy.
It all has to do it as efficiently as possible; Find the best combination of voltage and electricity to the maximum performance from the panels in a second basis from the panels to extract-day-in, day in all possible conditions for many years. Good inverters should take 10-20 years, but do not expect a cheaper to make it over 10.
5 types of residential judges
- String: the most frequently used type for residential complexes. It is installed on a wall for the size of a briefcase.
- Micro: As the name suggests; Much smaller and over the size of a paperback. Instead of hanging on a wall, micro -offers are installed under the panels. Usually one for every panel.
- Optimized string: combines a single large solar inverter with small devices that are assigned to each field to optimize the performance.
- Hybrid: is used instead of a string inverter so that you can simply add batteries later.
- Modular hybrid: A new interchangeable type that is used in some modular energy storage systems. The inverter module can be bought first and the battery and other modules (e.g. EV charger), which are stacked directly below at a later date.
In the video above, the Solarquotes founder Finn Peacock offers more details about the applications for each of the above, or you can read more in our solar inverter manual. But summarize:
- If you only have solar collectors installed, the GO is a good string inverter.
- If you buy a house battery in the next few years; Consider a hybrid inverter to make the battery installation cheaper. However, this can also lock this into certain batteries.
- If you have really complicated roof or want your system to run with safer tensions, you should take into account micro -offerers that optimize each field individually.
Selection of solar change judges
There are more solar inverter brands in Australia than you can stick a stick. This is unable to browse a stick with more than 114 of them. This is the number of brands with models that were currently approved by the Clean Energy Council (CEC) for use in Australia. The units on the Australian market are available for these.
The CEC permit is a must if you want to claim the upcoming Battery Battery discount and some state incentives and if you want to connect the solar inverter to the mains grid.
In general, brands can be used in one of four price categories.
The intended brand examples are currently recommended by solar quotes.
Decent 10-kilowatt (KW) budget-end-solar inverter can only cost $ 1,500, while at the end of the premium you can see about $ 3,600 to $ 4,000. And top-end systems cost even more (~ $ 5,500).
The quality of the brands varies in each category, especially in the budget end of the price range. And even within CEC-recognized devices in the same price category, not all are the same. Apart from hardware and software quality, one of the attributes that mark brands is an Australian office. If something goes wrong, you want someone to take care of your installer to repair it.
In a related note, Solar inverter -Garantia from 5 to 15 years, and some brands enable you to extend the guarantee for an additional fee. However, the guarantee length is not necessarily an indicator of quality. Many manufacturers who offer long guarantees have disappeared over the years, so that Australian customers are high and dry. It is also important to check the fine pressure of the guarantees on ridiculous conditions. For example, to send back to China after repairs.
The selection of an inverter can be time -consuming. However, if you would like to have a short average to put a list of good quality competitors in Australia, see the solar inverter stamps recommended by solar quotes in each category.
In view of the fact that a solar inverter works, Finn’s advice is to buy a recommended medium-class brand to Premium, instead of a budget model and only use micro-offer if you really need the advantages you can offer.
About “oversized”
In a solar system, the panel capacity is often more than the inverter capacity. For example, it is common to combine 13.3 kW panels with a 10 kW inverter. This “oversize” is a permitted and recommended practice. Among the advantages:
- Offers more strength in the morning, in the afternoon and when the sun is not super strong.
- This also gives them more solar discount, since the subsidy is based on the capacity of the panel and not on the inverter capacity.
Without batteries, you can be 33%oversized. If you have batteries and assume that the manufacturer allows this, you can use the double amount of panel capacity with a regulatory gap than the output power of the inverter.
Inverter monitoring
Most inverters have lights in the housing that tell them their operating status, and some will have a screen that provides further details. Almost all of them also offer an app for more detailed information these days.
While a standard app can tell you how much strength you have generated on the current day or in the past and what you are creating, the good ones will also tell you how much grid current and how much solar your home uses.
However, if you buy an EL-Cheapo solar inverter, you will probably not receive this last function. So you will be in the dark how much solar power is used by your home – which is somehow useless. You need this function.
Installation: place, place, place
Closing; Heat is the enemy of a change of sun. A good way to kill one before his time is to install the device where it is exposed to direct sunlight. This can also kill your guarantee because some manufacturers need installation in a shaded position.
While a garage is the best place for your inverter, the next best place is next to your measuring caste if this is not an option. If this area is unabashed, let yourself be put on a simple shadow. Model-specific covers are best if you are ready to pay $ 200-300.
