In terms of electrical specifications, both chargers are pretty similar with the exception of some features like having a screen on the Zappi as opposed to the Wattpilot, and the Wattpilot being smaller in size.

Let’s talk about each charger and their range of models.


There are 2 versions of the Wattpilot, Go (11-22kW) and Home (11-22kW).

The home is designed to be permanently installed on properties, suitable for both indoor and shaded outdoor areas.

The go is designed for transportation whilst travelling. This version is detachable and offers both solar or grid charging if and when available at your location.

Does the Wattpilot offer an APP?

The Fronius Wattpilot offers an app for easy visualisation and access to information of how your charger is performing, charging modes, and updating software easily. This app is available for both phones and tablets.

Can the Wattpilot charge from Solar?

Yes, the Fronius Wattpilot can charge directly from Solar energy with its dynamic load balance feature which allows the charger to optimally charge your electric vehicle in accordance with your home’s usage.


There are multiple versions of the Zappi charger, and it may seem confusing at first but when you see the table below, it will make more sense.

There are 8 versions of the Zappi charger, 4 white versions and 4 black versions. Within those 4 versions for each colour, there are an untethered and tethered option as well as the single or three-phase versions.

Does the Zappi offer an APP?

Yes, Zappi offer a free custom app where you can analyse live data from your charger, control modes, and allow you to control myenergi devices such as eddi, harvi and of course, the Zappi.

Can the Zappi charge from Solar?

Yes, the Zappi can charge from excess solar in the ECO and ECO+ modes. This allows the charger to utilise any excess solar energy and put it into your electric vehicle.

EV Charging Modes

Fronius Wattpilot Electric vehicle charger australia

Standard Mode

This is the standard charging mode and can be charged in increments with the push button and charges from both from excess solar and the grid.

ECO Mode
The charging mode designed for Solar system owners that want to charge their electric vehicle with solar if excess solar power is available.

Next Trip Mode
For those wanting to reliably charge their EV as fast as possible, or a specific amount, and it will calculate and intelligently charge to the required amount.

ECO Mode
This mode is a solar based charging method and reacts to fluctuations in solar productivity and switches to grid energy if solar is not available.

ECO+ Mode
This mode is similar to ECO, but instead of switching to grid energy when solar energy is unavailable, the charger switches off and only continues when solar becomes available again.

This is their standard mode that will charge the vehicle as fast as possible.

What Security does the Wattpilot have?

The Wattpilot can be secured with an approved RFID chip or card. The charger also consists of an anti-theft system for your type 2 charging cable, with a shackle and locking option available.

What Security does the Zappi have?

The Type 2 socket version (untethered) has a built-in locking system. The Zappi also can be secured by a 5-digit pin, which will need to be entered every time you use it. From what we can see, the Zappi does not offer an RFID system like the Wattpilot.

What are the Pro's and Con's of the Wattpilot?


  • Smaller than the Zappi charger.
  • Has RFID and can be set up with multiple users.
  • Seamless integration with Fronius products.


  • Both 11kW models can only charge at a maximum of 3.68kW on single phase, so to get the most out of your charger on single phase you will need to get the 22kW version which maxes out at 7.36kW.
  • The Wattpilot only charges with solar if you own a Fronius Solar inverter.
  • You will need to buy an additional charging cable as it doesn’t include one. (Untethered).
  • Only a 2-year warranty. (3 years with the Zappi).
  • Charger cannot be exposed to direct sunlight.

What are the Pro's and Con's of the Zappi?


  • Can work with any inverter.
  • LCD Screen (No screen on the Wattpilot).
  • 3-year warranty (+1 year more than the Wattpilot).
  • More style/functionality options (Colour and tethered options).


  • No RFID card or system, only a pin lock.
  • It’s bigger than the Wattpilot.
  • It's also heavier (3.3 kg vs. Wattpilot's 1.82 kg - both 22kW models).

Which one to get? Zappi vs. Wattpilot Ev Charger

We've looked at a summary and both of the products' details, but what do they have in common?

  • Both automatically switch between single and three phase.
  • Both can charge with Solar energy.
  • They both have products that cap at 22kW.
  • Both are the same IP rating (IP65).
  • The chargers can charge EV’s with solar at a minimum of 1.38kW, soaking up every bit of solar energy.

So what now? How do you decide?

This decision will come down to a couple of things; budget, security, and size. The Zappi does not offer RFID functionality, and is bigger than the Wattpilot, however the Wattpilot is only compatible with Fronius Inverters and may not be compatible with your existing solar system.

Both chargers will charge with solar if that is your main goal, so it is up to you whether you value having something smaller, if you want a charger that you can unlock with a swipe, if 2-year warranty is too little, or if you're looking for more variety in styles and capabilities.
