The brains of the system, not only does an inverter invert (turning direct current (DC) produced by solar panels into the alternating current (AC) you use in your house), they can also:

  • control your solar panels;
  • charge and discharge your batteries;
  • integrate a generator or other power generation;
  • export to and import from the grid; and
  • provide you with the information to keep an eye on what’s going on.

So which brands do we install? Fronius and Victron, two of the absolute best brands available.


The Austrian company, Fronius, has long been producing inverters that have topped lists of the world’s best inverters.

Their inverters bring peerless European engineering and finish quality, alongside market-leading efficiency.

Producing inverters that can be used in the biggest commercial applications through to smaller household grid-tie
installations, the latest Gen24 range for residential use can literally do it all – solar controller, battery charger, inverter,
grid connection and top-notch monitoring from your phone.

Fronius inverters come with a 5-year warranty.

Fronius Gen24 & Gen24 Plus

The inverter that has quickly become the gold standard for grid-tie applications.

The upgradeable Fronius GEN24 inverter provides you with efficient, reliable, direct use of the solar energy you generate at home.

When upgraded to the ‘Plus’ configuration, it can be connected to a BYD HV battery, providing you with additional flexibility and security.

Available from 3 to 10 kW in both the single phase ‘Primo’ and three phase ‘Symo’.

Being such a highly efficient AC-coupled inverter, we often also spec one in a larger off-grid system where there are significant daytime loads.


Victron EasySolar-II

The all-in-one solar power solution,

The Victron EasySolar-II GX integrates the following into one unit:

  • A MultiPlus-II inverter/charger
  • A SmartSolar MPPT solar charge controller
  • A GX device with a 2 x 16-character display.

This means it can:

  • Be the brain for your solar panels;
  • Prioritise the PV-produced power for your household needs, or if not required, use the excess to charge your battery;
  • Pull energy from your battery for your household needs;
  • Connect to the grid supply, allowing supplementation of your household loads and charging of your battery from the grid, if required; and
  • Provide connectivity for monitoring.

The EasySolar-II is grid-compliant (i.e. the lines companies allow it to be connected directly to the grid).

Available in 24V and 48V 3kVA and 48V 5kVA models.

Victron Multiplus / Multiplus-II

One of our go-to inverters for systems with a 12V, 24V or 48V battery set-up, the MultiPlus and Multiplus-II are combined inverter and chargers in one elegant package.

The Multiplus is generally deployed in off-grid systems, with the AC input allowing connection to and management of a back-up power source, such as a generator.

The Multiplus-II has all the features of the Multiplus, but is designed to also work seamlessly in grid-tie systems, having the necessary hardware for grid-compliance.

Taking three units of the same model, both the Multiplus and Multiplus-II, can be configured for three phase supply.

Multiplus available in 12V 800VA-3kVA; 24V 800VA-5kVA; and 48V 3kVA-5kVA models.

Multiplus-II available in 12V 3kVA; 24V 3kVA-5kVA; and 48V 3kVA-15kVA models. 24V and 48V 3kVA and 48V 5kVA GX models also available.

Victron Quattro

Similar to the Multiplus/Multiplus-II in functionality, but with a second AC input.

This second AC input opens up options such as including a second generator or having a back-up generator alongside a grid connection.

We often use the Quattro within larger systems (8kW upwards) when integrating with a 48V battery setup.

As with the Multiplus/Multiplus-II, the inclusion of three units allows three phase configurations.
