Fronius Wattpilot Flex Home 22 C6

Compatibility

Compatible with EpiSensor Edge through a ZEM-65 on the charger supply

Fronius documents OCPP 1.6 J for a charging management system, set from the Solar.wattpilot app. Edge does not speak OCPP, so that link stays with the CSMS. Edge measures the charger through an EpiSensor ZEM-65 electricity monitor with CTs on its three-phase supply, which records energy, power and current per phase and sends them to the Gateway over the EpiSensor wireless network.

Exact Wattpilot Flex Home 22 C6 with its six-metre Type 2 tether and no plug shutter; Home 11 C6, shutter-equipped Home 22 CP6 and Pro 11/22 C6E are distinct configurations. ISO 15118 and BLE are described as hardware-prepared, not active software integrations. Site check: fit the ZEM-65's 120 A split-core CTs on L1, L2 and L3 of the charger's dedicated circuit.

Models

Specifications

The exact Home 22 C6 table specifies a 6 m Type 2 cable, configurable 6–32 A, up to 7.4 kW single-phase or 22 kW three-phase, LAN or Wi-Fi networking, and OCPP 1.6 J. The Home charger is not an integrated MID billing meter. Fronius also warns that high continuous current can derate at elevated ambient temperature.¹

Charging hardware

Mode 3 AC, six-metre tethered Type 2 plug; C6 has no CP6 plug shutter¹

Electrical range

Configurable 6–32 A, one or three phases; 7.4 kW single-phase or 22 kW three-phase maximum at the stated nominal voltages¹

Thermal limit

At 45 °C, 3 × 32 A can derate to 3 × 27 A after one hour; avoid direct sun and design for the installed ambient conditions¹

Networking and protocol

10/100 Mbit/s LAN, 2.4 GHz Wi-Fi and OCPP 1.6 J to an external charging management system^1, 3

Authentication and metering

RFID or Solar.wattpilot app; no integrated MID meter and no measurement-law compliance claim for this Home variant¹

Prepared interfaces

ISO 15118 and Bluetooth Low Energy are hardware-prepared; do not assume active Plug & Charge, V2G or BLE integration¹

Siting and protection

IP66, IK08, -25 to +45 °C. External RCD and circuit breaker remain required to local installation standards despite integrated 20 mA AC / 6 mA DC residual-current detection.¹

Interface

Documented measurements and integration boundaries for Wattpilot Flex Home 22 C6.

• Solar.wattpilot shows charging sessions and charging amounts within the Fronius system; the manual gives no MID accuracy class for the Home 22 C6.
• The app's OCPP status distinguishes network connection from CSMS acceptance. Record both the server-side identity and accepted state before relying on management functions.
• PV surplus charging and dynamic load balancing require the documented Fronius system components and settings. Site meter headroom is a separate measurement boundary.
• Fronius documents MeterValues, StatusNotification, StartTransaction and StopTransaction for monitoring. Smart charging includes SetChargingProfile and ClearChargingProfile; GetConfiguration and ChangeConfiguration have limited support. Charging schedules use amperes. These are CSMS functions, with site permission required for control.

Setup

1. Confirm the label reads Wattpilot Flex Home 22 C6 and inspect the six-metre Type 2 cable.

   A CP6 shutter, 11 kW rating or Pro metering label changes the guide scope.

2. Have a qualified installer verify the one- or three-phase supply, upstream breaker and RCD, earthing, cable entry and permitted charging current.

   Set the app current limit to the site design and allow for documented high-temperature derating.

3. Use the Fronius Solar.wattpilot app to record the firmware version, configure Ethernet or Wi-Fi and check the local charging and RFID/app authorization behavior with a suitable vehicle.

4. If PV surplus or dynamic load balancing is required, commission the supported Fronius inverter and primary Smart Meter at the feed-in point, set phase assignment, and check the actual site headroom.

   Dynamic Load Balancing requires an Internet connection.

5. For OCPP, obtain a CSMS that accepts OCPP 1.6 J and its correct server address.

   Enter it under the app's Connection > OCPP settings, activate OCPP and identify the charger at the CSMS.

6. Check the app reaches Connected and accepted.

   Through the CSMS, read GetConfiguration for MeterValueSampleInterval, MeterValuesSampledData and SupportedFeatureProfiles. The Wattpilot family OCPP document 42,0410,2881 revision 002, 17 October 2024, gives a default sampling interval of 60 seconds and phase-current, phase/total-power and energy fields. Use this as a starting point and compare the actual Flex response once at commissioning. During a test charge, compare timestamps, units, active phases and the energy increase with Solar.wattpilot. Keep charging-profile changes separate from this monitoring check.

Common questions

Does Connected prove the charger is managed by the CSMS?

No. Fronius distinguishes Connected, where the connection has not yet been accepted, from Connected and accepted. Verify the latter and a bounded charging session at the CSMS.¹

Is Home 22 C6 a MID billing charger?

No. Its technical table says no integrated MID meter and no measurement-and-calibration-law compliance. A Home charging amount must not be presented as a certified billing reading.¹

Does ISO 15118 or BLE readiness enable Plug & Charge or direct app integration now?

The manual describes ISO 15118 and BLE as hardware-prepared, with no active software integration for either feature in this exact Home unit.¹

How does the charger connect to EpiSensor Edge?

Through an EpiSensor ZEM-65 with CTs on the charger's supply, which gives Edge energy, power and current per phase. Edge does not speak OCPP, so the OCPP 1.6 J connection in the Fronius instructions goes to a separately chosen CSMS.^1, 3
