What are the five best solar inverter brands in Australia?

When buying a solar system, it’s challenging to really know what’s good and what’s not.

After all, very few salesmen are going to tell you what they’re peddling isn’t very good. So this short guide provides  an indication of what some of the best inverter brands on the market are.

This doesn’t mean these are the only inverters worth getting, but it does mean that these five are considered to be the best of the best.

The top five inverters were selected according to the following criteria:

  • Quality/Value
  • Warranty
  • Presence in Australia
  • Monitoring (Optional)

Based on experience within the PV industry and working in a technical role, here are our Top five inverters, in order of preference:

1. SMA

SMA is a German manufacturer that has been around for a good number of years. They are a leader in the inverter manufacturer field and deservedly own a large share of the inverter market.

SMA is known for their quality, level of service and exceptional monitoring capabilities.

They are an easy choice for first place.

2. Solar Edge

Solar Edge fell just behind SMA because of a pricing element. They have a slightly different setup which uses ‘power optimisers’ on each panel as well as a central inverter. While this system does cost more it also allows each panel to be operated and monitored independently.

With connection via a web portal your system performance can be viewed from any computer you want as long as it has internet access, meaning it has one of the best monitoring solutions out there.

3. Aurora (Power-One)

Aurora is an Italian brand that has been around for a while and has a good reputation in the industry. They are a well priced reliable unit. The indoor model particularly, feature excellent and informative LCD displays.

What lets Aurora down is the lack of a good monitoring solution without buying additional attachments. However, if you don’t much care to monitor your system then this is a very solid inverter.

4. Fronius

Fronius and Aurora are very close and really Fronius is an equal 3rd to Aurora. As with Aurora these are a very reliable inverter that has been proven in the market over a long period and has a good reputation.

However, as with Aurora what pushes these guys down below Solar Edge is the lack of good in-built monitoring. Though there are monitoring solutions in place they are an additional cost and do not come built in like the >2kW SMA and Solar Edge inverters do.

5. Delta Inverters (SOLIVIA)

Delta Inverters are another solid option with all the main criteria. They are a solid quality build, they have a presence in Australia and they have a warranty that fully covers the full gambit of replacement costs.

What’s put them 5th on the list is the size of the units and their limited flexibility for system design. By sticking with a transformer these inverters are bigger than their transformerless contemporaries. Additionally with only one maximum power point tracker even at the 5 kW range means that you can only use one roof face which limits where these inverters can be effectively installed.

Summary

Any of the above inverters are excellent for use in a residential PV system.

All of them have good reputations for excellent build quality, technical support within Australia and warranties that don’t put you out of pocket if you need to use them.

If you choose to go with something different to any of the above though, be sure that whatever inverter you choose has these same qualities.

The worst thing that can happen is that you end up buying something that won’t last, is a hassle to get repaired/replaced and leaves you with a hole in your wallet.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
