Smappee EV Wall 22kW

Strengths

  • ✓ OCPP - open integration capability
  • ✓ Solar integration - CT clamp, any inverter
  • ✓ Load management
  • ✓ Whole-home energy monitoring via Smappee platform
  • ✓ 22kW 3-phase
  • ✓ 3yr warranty

Watch out for

  • ✗ $1,800 - same as Fronius Wattpilot

Our Verdict

The Smappee EV Wall 22kW combines OCPP, solar integration, load management, and whole-home energy monitoring at $1,800 - matching the Fronius Wattpilot on price with a broader energy monitoring capability. Its differentiation is the Smappee whole-home energy platform: if you want a single app to monitor total home energy consumption, solar generation, EV charging, and load optimisation, Smappee provides this natively. The trade-off is the Smappee hub (sometimes required separately) and a less established brand presence in Australia than Fronius or myenergi.

Overview

Smappee is a Belgian company specialising in whole-home energy monitoring and management. Their EV Wall charger extends the Smappee platform to include EV charging - making it the only 22kW charger that natively connects EV charging to whole-home energy visibility in a single platform.

At $1,800, it matches the Fronius Wattpilot on price. The differentiation is the energy monitoring depth: Smappee can track individual circuit consumption, not just total home draw. This makes it appealing for households with a strong interest in energy management and optimisation beyond simply scheduling charging.

The hub dependency

The Smappee EV Wall’s full feature set - particularly the whole-home monitoring and circuit-level visibility - requires the Smappee Energy Monitor hub. This is a separate device. If the full platform is the reason you’re buying the Smappee EV Wall, factor the hub cost into your total calculation.

Basic OCPP and EV charging functionality may work without the hub - confirm this with your installer for your specific requirements.

Fronius wins for Fronius inverter households where native API integration provides superior solar data. Smappee wins for households wanting whole-home energy visibility across all circuits. Smappee’s 3yr warranty is better than Fronius’s 2yr.

Who should buy the Smappee EV Wall 22kW

Best for:

  • Households already in the Smappee energy monitoring ecosystem
  • Buyers wanting whole-home energy management (circuit-level visibility) beyond just EV and solar
  • Three-phase properties where OCPP, solar, and load management are needed

Skip if:

  • Fronius inverter household - Wattpilot’s native API integration is better
  • Hub cost is a concern - add $300–$400 to total for full Smappee functionality
  • Established AU brand support is a priority - Fronius or myenergi have deeper local presence

Frequently Asked Questions

01 Does the Smappee EV Wall require a separate hub?

Some Smappee EV Wall configurations require the Smappee Energy Monitor hub for whole-home energy monitoring and advanced load management features. The hub itself costs approximately $300–$400 additional. Confirm with your installer whether the hub is needed for your specific use case - basic OCPP and charging functionality may work without it, but the full Smappee platform experience typically requires the hub.

02 What is the total installed cost of the Smappee EV Wall 22kW?

Supply price $1,800 plus 3-phase installation of $600–$1,000. If a Smappee hub is required, add $300–$400. Total all-in approximately $2,400–$3,200 depending on hub requirement.

03 Smappee EV Wall vs Fronius Wattpilot Home 22J - same price, which is better?

Fronius Wattpilot ($1,800): native Fronius Solar.web integration, OCPP, solar, load management, 2yr warranty. Smappee EV Wall ($1,800): OCPP, solar, load management, whole-home energy monitoring, 3yr warranty, potentially separate hub cost. For Fronius inverter households, the Wattpilot's native integration is unmatched. For households wanting whole-home energy monitoring beyond just EV and solar, Smappee offers a broader platform. Hub cost may tip the total toward Fronius for overall value.

04 What does 'whole-home energy monitoring' mean in practice?

Smappee's platform monitors electricity consumption at the circuit level (with additional current clamps) - tracking which appliances use the most energy, not just total home consumption. For the EV charger specifically, this means accurate per-session energy allocation, visibility of EV charging cost against household consumption, and load management that coordinates the charger against other high-draw appliances.

05 Does the Smappee EV Wall work with non-Smappee solar inverters?

Yes. CT clamp integration works with any grid-connect inverter. The Smappee platform adds a broader energy monitoring layer on top of the solar tracking capability.
