EVC22-3AC-20

The SMA eCharger EVC22-3AC-20 is SMA Solar Technology’s intelligent three-phase wallbox with 22 kW power, designed to charge your electric car at home quickly, safely, and fully integrated with your photovoltaic system. With adjustable power from 1.38 kW to 22 kW and automatic phase switching, it adapts to any usage scenario—from slow overnight charging to solar charging at the maximum available power.

Integrated Solar Charging — Maximum Photovoltaic Self-Consumption

The real strength of the EVC22-3AC-20 is its native integration with the SMA Sunny Home Manager 2.0. The system monitors photovoltaic production and household consumption in real time, automatically adjusting the charging power to prioritize the use of surplus solar energy. The concrete results:

• 100% solar energy charging during peak production hours
• Automatic single-phase↔three-phase switching — switches from 1 phase (minimum 1.38 kW) to 3 phases (maximum 22 kW) based on solar energy availability, while respecting the vehicle’s minimum charging threshold
• Boost function — when needed, supplements solar power with grid power to achieve maximum charging speed
• Save up to 80% on charging costs compared to public charging stations

How fast does it charge your electric car?

At 22 kW three-phase, the EVC22-3AC-20 typically adds over 100 km of range for every hour of charging. Here are some concrete examples with the most popular models in Italy:

• Tesla Model 3 / Model Y (11 kW AC onboard charger) — full charge in about 5–6 hours
• Volkswagen ID.3 / ID.4 (11 kW AC) — 0 to 100% charge in about 6 hours
• Renault Zoe (22 kW AC) — fully utilizes 22 kW, full charge in about 3 hours
• BMW iX / i4 (11 kW AC) — full charge in about 5–6 hours
• Fiat 500e (11 kW AC) — full charge in about 4 hours
• Peugeot e-208 / e-2008 (11 kW AC) — full charge in about 4 hours
• Hyundai Ioniq 5 / Kia EV6 (11 kW AC) — full charge in about 5 hours
• Plug-in hybrid PHEV vehicles (3.7–7.4 kW AC) — the wallbox automatically adapts to the power accepted by the vehicle

The Type 2 socket with shutter is compatible with all electric and plug-in hybrid vehicles sold in Europe equipped with the IEC 62196-2 (Type 2) standard connector, including Tesla (via the integrated European standard adapter).

Certified Safety — Integrated Protections

The EVC22-3AC-20 includes all protections required by the Italian CEI 64-8 section 722 standard without the need for additional components:

• Integrated 6 mA DC residual current protection — eliminates the cost and bulk of an external type B RCD
• Blackout protection — detects power outages and suspends charging, preventing damage to the vehicle and system
• IP54 protection rating — suitable for installation in closed garages as well as semi-open or covered outdoor spaces
• IK10 impact resistance — the highest class of mechanical impact resistance
• Made in Germany, 5-year SMA warranty

Access and Management — RFID, App, and Portal

Charging access is controlled via the integrated RFID reader (includes 2 SMA RFID cards). Those with multiple vehicles or who share the wallbox with family or colleagues can assign personalized cards with session logs. Remote management is possible via:

• SMA Energy App — real-time monitoring, start/stop sessions, charging statistics
• SMA eMobility Portal — centralized management for multi-point installations, ready for OCPP 1.6 billing
• Integrated webserver — configuration and monitoring from a local browser without an app
• LCD display — charging status, delivered power, and messages directly on the wallbox

Connectivity and Smart Home Integration

The EVC22-3AC-20 offers complete connectivity for integration into smart systems and energy management setups:

• 2 Ethernet LAN ports + WLAN — for connection to router, switch, or directly to Sunny Home Manager
• RS485 + Modbus TCP with SMA profile — for integration with BMS, BEMS systems, and building automation
• 6 digital inputs / 1 digital output — for external signals (charging lock, tariff signal, etc.)
• OCPP 1.6 — ready for billing and fleet management
• SMA Smart Connected — proactive diagnostics and remote SMA support

Bonus Charging Stations 2026 — May Be Eligible for Incentives

The installation of a home wallbox may benefit from the Bonus Colonnine (annual update by MASE), which provides a non-repayable grant for the purchase and installation of private charging infrastructure. Check with your installer for eligibility under the latest conditions, as requirements and percentages vary from year to year.
