The myenergi Zappi has become one of the most popular home EV chargers in Australia. It is a smart charger designed to charge an electric vehicle from surplus solar. A charger is not tied to one inverter brand. It works with almost any solar system. This review explains what the Zappi is, how its charging modes work, why being system-agnostic matters in Perth, and the households it suits best.
The short verdict is that the Zappi is the flexible all-rounder of home charging. If a household wants strong solar-surplus charging that is not locked to a single inverter brand, it is very hard to beat. This is why Positive Energy Solutions frequently pairs it with a Sungrow system. We fit it across many others.
What the Zappi Is
The Zappi is a dedicated wall charger made by myenergi. Like any home charger it uses the standard Type 2 connector fitted to every electric vehicle sold in Australia. Its defining feature is intelligent solar charging that does not depend on the brand of inverter on the wall. It monitors the flow of power at the home’s meter. It diverts surplus solar into the car. Energy that would otherwise be sent to the grid at a low feed-in rate is used to add kilometres instead.
Three Charging Modes
The Zappi offers three charging modes. This lets a household choose between speed and solar savings depending on the day.
| Mode | In short | How it works |
|---|---|---|
| Fast | Charge now | Charges at full available power from any source, for when the car is needed quickly regardless of solar |
| Eco | Solar-led | Charges continuously, blending surplus solar with a minimum of grid power, and adjusting as solar rises and falls |
| Eco+ | Solar-only | Charges only from genuine surplus solar and pauses when there is not enough, for the lowest-cost possible charging |
For a Perth home chasing the lowest running cost, Eco+ is the mode that matters. It ensures the car draws only the solar the home is not using. Midday surplus that would send out for a few cents becomes driving on your own solar. Fast mode is there for the days a car simply needs to be ready. Eco sits sensibly between the two.
Solar Charging Without a Separate Hub
A practical strength of the Zappi is that it has WiFi and Ethernet built in as standard. It connects and updates without a separate hub. Where the charger needs to see exactly how much power is flowing to and from the grid, a small myenergi sensor called a Harvi can be added. It reads that flow wirelessly. The whole system is then controlled and monitored through the myenergi app. A household sets its mode there and watches how much of its charging came from solar.
Tethered or Untethered
The Zappi comes in two forms. A tethered unit has a Type 2 charging cable permanently attached. This is the most convenient for daily use. Simply unhook and plug in. An untethered unit has a socket instead. The household uses its own cable. This keeps the unit tidy and lets a longer or shorter cable be chosen. Both are built for permanent outdoor installation in Perth conditions.
Why System-Agnostic Charging Matters
Most brand-specific chargers integrate best with their own inverter. The Zappi takes the opposite approach. It works with whatever solar system a home already has. This makes it the sensible choice in two common situations. The first is a home whose inverter brand does not offer a charger the household wants. The second is a home that wants the freedom to change or expand its solar later without replacing the charger. In practice, Positive Energy Solutions often pairs the Zappi with a Sungrow system. The combination gives strong solar charging without tying the household to a single ecosystem.
Zappi Specifications at a Glance
- Charging power: 7.4 kilowatts on a single-phase supply (32 amps) or 22 kilowatts on three phase (32 amps).
- Charging modes: Fast, Eco and Eco+ for solar-surplus charging.
- Connectivity: WiFi and Ethernet built in, no separate hub required; optional Harvi sensor for grid monitoring.
- Cable: available tethered (attached Type 2 cable) or untethered (socket).
- Load management: dynamic load balancing so the charger never overloads the home’s supply.
- Connector: standard Type 2, compatible with every electric vehicle sold in Australia.
- Installation: built for permanent outdoor mounting.
Who the Zappi Suits
The Zappi suits almost any Perth household that wants excellent solar-surplus charging. It must not be locked to one inverter brand. It is a particularly good match for a Sungrow home. It also suits any household that values being able to change its solar setup down the track. A home fully invested in a single ecosystem, such as Fronius, SigEnergy or Tesla, may prefer that brand’s own charger. This gives tighter integration, which is the kind of trade-off a proper system design weighs up.
How Positive Energy Solutions Can Help
Positive Energy Solutions supplies and installs the Zappi across many system types. We match it to the home’s solar and electricity plan so it charges from the lowest-cost energy available. Every charger is installed by our accredited installers on its own circuit. We follow the current wiring rules and Western Power requirements. The solar system feeding it is backed by a 10-year installation workmanship warranty and Positive Energy Protection, powered by Omnidian. It is monitored for performance from day one.
Frequently Asked Questions
Does the Zappi work with any solar system?
Yes. The Zappi is system-agnostic. It charges from surplus solar regardless of the inverter brand. This is its main advantage. It monitors the power flowing at the home’s meter. It diverts spare solar into the car. So it suits homes on almost any solar setup. It is often paired with Sungrow.
What is the difference between Eco and Eco+ mode?
Eco mode charges continuously. It blends surplus solar with a minimum of grid power. Eco+ mode charges only from genuine surplus solar. It pauses when there is not enough. This gives the lowest-cost possible charging but may pause on cloudy days. Fast mode charges at full power from any source when the car is needed quickly.
Do I need a hub for the Zappi?
No. The Zappi has WiFi and Ethernet built in. It does not need a separate hub to connect. Where it needs to measure the power flowing to and from the grid, a small myenergi Harvi sensor can be added. It reads that flow wirelessly.
How fast does the Zappi charge?
The Zappi charges at up to 7.4 kilowatts on a single-phase supply. This suits most Perth homes and refills a typical day of driving overnight. It can also charge at up to 22 kilowatts on a three-phase supply.
Charge From Your Solar, Whatever Your System
For a Perth home that wants flexible, solar-first charging, the Zappi is one of the strongest options available. It must not be tied to one inverter brand. The right setup depends on the home’s solar, supply and parking. A Positive Energy Solutions consultation is designed to match these.
