Evnex E2 Plus vs Myenergi Zappi: Which Solar EV Charger Is Better in Australia?

If you have rooftop solar and you’re buying a home EV charger in Australia, you’ve probably narrowed it down to two names: the Evnex E2 Plus and the myenergi Zappi. They’re the two most credible solar-capable smart chargers on the market, they’re within $51 of each other, and they both use CT clamp solar diversion that works with any inverter.

This comparison breaks down every difference that actually matters — price, solar modes, OCPP, load management, warranty, installed cost, and the scenarios where each one wins.

The short answer

The Evnex E2 Plus offers more features at a lower price. The Zappi has a longer track record in Australia and deeper ecosystem integration. For most new buyers starting fresh, the E2 Plus is the stronger package. For buyers committed to the myenergi ecosystem or who specifically want the most field-tested solar diversion, the Zappi is the right pick.

Price and installed cost

The E2 Plus is $51 cheaper at supply price and tracks roughly $50 cheaper at the installed level. Neither charger’s installation is meaningfully different in complexity — both require a CT clamp at the switchboard and standard single-phase wiring.

	E2 Plus	Zappi
Supply	$1,299	$1,350
Installation	$450–$750	$450–$750
Total	$1,750–$2,050	$1,800–$2,100

The price gap is narrow. Neither charger wins or loses on price alone.

Solar charging: how they compare

Both chargers use the same fundamental approach — a CT clamp at the switchboard monitors solar export and adjusts charging speed to absorb surplus generation. Neither requires API access to your inverter. Both work with Fronius, SolarEdge, Sungrow, GoodWe, Enphase, and every other grid-connect system.

The difference is in how they implement solar modes.

Zappi: three modes

• Fast — full grid power, ignores solar entirely
• Eco — uses solar surplus, tops up from grid to maintain a minimum charge rate (configurable from 6A upward)
• Eco+ — solar only, pauses charging when surplus drops below threshold

The Eco/Eco+ distinction and the configurable minimum boost current give the Zappi the most fine-grained solar control of any home charger in Australia. If you want precise control over how much grid top-up is allowed during solar charging, the Zappi is harder to beat.

Evnex E2 Plus: two modes

• Solar-only — charges exclusively from surplus, pauses when solar drops
• Hybrid — charges from solar when available, supplements from grid to meet a departure time target

The E2 Plus’s hybrid mode is more practical for most households — it ensures the car is always ready by departure time while maximising solar use. The Zappi’s Eco mode achieves something similar but requires more manual configuration.

Verdict on solar

The Zappi offers more control. The E2 Plus offers a more practical “set and forget” hybrid mode. For enthusiasts who want to fine-tune every kilowatt, the Zappi wins. For most households who want smart solar charging that just works, the E2 Plus is equally effective with less fiddling.

OCPP

This is the E2 Plus’s clearest advantage.

Evnex E2 Plus: OCPP 1.6 — enables scheduled charging, solar-aware scheduling, remote session management, and energy reporting through the Evnex app. The implementation is closed (Evnex cloud only, not open to third-party OCPP backends), which limits power-user scenarios but is transparent for residential use.

Zappi: No OCPP. Uses myenergi’s proprietary protocol. Cannot integrate with third-party charge management platforms or Home Assistant OCPP integrations.

In states where OCPP compliance is emerging as a grid connection requirement for high-amperage chargers, the E2 Plus is future-proofed. The Zappi is not.

Load management

E2 Plus: Dedicated load management using the CT clamp. The charger monitors total home current draw and reduces charge rate before the main fuse is overloaded. The solar CT clamp does double duty for load management, meaning no additional hardware.

Zappi: No dedicated load management. The CT clamp data is available in the app but the Zappi doesn’t automatically throttle based on household load. In older homes with smaller main fuses, this is a practical disadvantage.

For homes on 40A or 50A single-phase supply — common in older Australian houses — the E2 Plus’s automatic load management avoids the risk of tripping the main breaker when the charger runs alongside air conditioning, ovens, or hot water.

Warranty

• E2 Plus: 4 years
• Zappi: 3 years

One year longer. Both are above the 2-year standard that most sub-$1,500 chargers offer. The E2 Plus’s 4-year warranty is the best in the solar charger category at this price point.

IP rating and outdoor suitability

• Zappi: IP65 — protected against water jets from any direction
• E2 Plus: IP55 — protected against low-pressure water jets

Both are rated for outdoor installation. The practical difference matters in fully exposed, unsheltered locations — think a wall-mounted charger on the side of the house with no eaves, directly exposed to driving rain. In that scenario, the Zappi’s IP65 provides extra confidence. For garage, carport, or semi-sheltered installations, IP55 is perfectly adequate.

The myenergi ecosystem advantage

The Zappi integrates natively with two other myenergi products:

• Eddi — a hot water diverter that sends surplus solar to an immersion heater or heat pump hot water system
• Libbi — myenergi’s home battery that coordinates with the Zappi and Eddi for whole-home energy optimisation

If you’re building a complete solar self-consumption system — EV charging, hot water, and battery storage all managed from one app — the myenergi trio is the most integrated option available. No other manufacturer offers this level of cross-product solar coordination.

The Evnex E2 Plus is a standalone product. It does EV charging exceptionally well but doesn’t extend into hot water or battery management.

Cable length

A minor but practical difference:

• Zappi: 6.5m tethered
• E2 Plus: 6m tethered

The 0.5m difference rarely matters, but if your charge point is mounted at the far end of a long garage, every centimetre counts.

Who should buy the Evnex E2 Plus

• You want OCPP alongside solar charging
• Load management matters (older home, smaller main fuse)
• You want the longest warranty available at this price
• You’re a new buyer with no existing myenergi products
• Budget is tight and you want the most features per dollar

Who should buy the Zappi

• You want the most field-tested solar EV charger in Australia
• Fine-grained solar mode control (Eco vs Eco+, configurable minimum boost) is a priority
• You’re building a myenergi ecosystem with Eddi and/or Libbi
• The charger will be installed in a fully exposed outdoor location (IP65)
• You value proven Australian track record over newer feature sets

The bottom line

The Evnex E2 Plus is the better-specified charger at a lower price. OCPP, load management, a 4-year warranty, and $51 less than the Zappi make it the stronger all-round choice for most Australian solar households buying a charger in 2026.

The Zappi remains the right choice for buyers who specifically want the most mature solar diversion platform in Australia, or who plan to build out the full myenergi ecosystem. Its three solar modes offer more control than the E2 Plus, and its longer field history in Australia means fewer unknowns.
