How to Compare Solar Inverters

Number of MPPT

MPPT, or Maximum Power Point Tracker, is a circuit within most new inverters which acts to optimise the energy production of your solar power system by making it operate at the most efficient voltage, ie; the maximum power point. You need multiple MPPTs if you have your solar panels mounted across multiple roof areas, and each roof area points in a different direction. This is because you each string will have different amounts of sun falling on it due to their different directions, therefore they will have different shape IV curves, and different max power points. So you need an MPPT for each string to get maximum performance from your system as a whole.

Number of MPPT

It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.

Noise

Many customers ask if the inverter will be noisy, especially if installed near bedroom windows etc? The high quality inverters are usually very quiet and you will hardly be able to hear them. Cheaper models, particularly older generation inverters with transformers, are often characterised by a monotone hum and buzz, especially during periods of high output. Consider that even if installed near a bedroom window, the inverter switches off during the night. Nevertheless for shift workers etc the lesson is – buy a quality inverter and try to install the inverter near the switchboard and not direct outside the bedroom window. Suggest your preferred position to the solar system installer and also do not put the solar inverter where it is exposed to direct sun for long periods of the day.

Brand and Reputation

The brand and reputation of inverter brands is really an important factor to the customers. The main criteria that qualifies a brand to be recognised is:

  • Has an Australian office for warranty support
  • Has straightforward and easy-to-navigate phone/email support for warranty issues
  • Has a good reputation in the industry
  • Has not been flagged by the CEC for any major violations
  • According to the criteria, Goodwe, Sungrow and Solaredge are the manufacturing brands has a good reputation amongst all the solar inverter brands.

What the warranty covers

Inverter warranties have to this point almost always been for five years. Some manufacturers like Fronius have been offering special +5 year upgrades if you register the inverter and your details with them. It is important to understand though that these bonus warranty upgrades may not cover labour or freight and may just cover the product. Still, this is good value considering a replacement 5kW inverter can set you back up to $2500 installed when a +5 bonus warranty turns this into a callout or two and some interstate freight costs.
We are starting to see some manufacturers increase their warranties to 10 years or more. For example, Enphase warrant their microinverters for 10 years and SolarEdge warrant their inverter for 12 years (SolarEdge also warrant their optimisers for an incredible 25 years)
Most manufacturers also offer upgrade options that can extend the warranty up to 10/15/20/25 years. These extensions are generally not free and may be offered at the time of the sale or the time of the installation. Additional warranties can provide good value if they are low in cost, but it is important to understand how much the price will rise.
