FIMER FLEXA AC Wallbox – Stand Alone

The Stand Alone variant of the FLEXA AC Wallbox is FIMER’s basic version designed to provide a straightforward solution for electric vehicle charging. It comes equipped with features aimed at ensuring a simple and efficient charging process

Key Features:

  • Bluetooth Communication: Allows for easy setup and management through the MyFIMERwallbox mobile app.
  • RFID Technology: Enhances security with authentication and unlocking systems via a customer RFID key card.

FIMER FLEXA AC Wallbox – Future Net

The Future Net model of the FIMER FLEXA AC Wallbox expands upon the basic Stand Alone version by incorporating advanced connectivity options. It is capable of connecting to backend systems through the OCPP 1.6 Json communication protocol, which means you’ll be able to connect to current and future 3rd party applications.

Key Features

  • Enhanced Connectivity: Offers Bluetooth, Wi-Fi, 3G/4G, and Ethernet for broader remote management options. Importantly this enables remote updates for the firmware of the charger which isn’t possible on the Stand Alone model.
  • OCPP 1.6 Json Protocol: Open Charge Point Protocol (OCPP) is a common language that can connect your EV Charger with third party applications.
  • RFID Authentication: This EV Charger has RFID capability built in which is particularly useful for enabling quick activation of the EV charger in public areas..
  • Solar Charging: The Future Net version can be paired with a solar system, however it requires third party hardware and software for this to be enabled. The charger will require a minimum of 2.5kW of surplus solar power for EV Charger to activate which is a greater requirement than some other EV chargers.

Power Options and Variants

Both variants in the FIMER FLEXA AC Wallbox series is available in several configurations to meet diverse user requirements:

  • Single-Phase 7.4KW or 3-phase (22kW)
  • Tethered version with 5m cable or untethered with a type 2 socket

Installation Considerations

Installation of the FLEXA AC Wallbox is recommended to be performed by a professional to ensure safety and optimal functionality. 

Both indoor and outdoor installations are possible, though the IP55-rated design primarily favours indoor settings with the recommendation being to purchase a cover should you need this unit for outdoor use.

If you are looking to connect this EV Charger to a solar system, it would be essential to find an installer that has experience with this as it requires 3rd party hardware and software.

Warranty and Service

FIMER backs the FLEXA AC Wallbox with a 2 year warranty. This is towards the shorter end of the warranties available for EV Chargers. 

For an additional cost, customers can extend the 2 year warranty to a maximum of 5 years.

The presence of an Australian office is always a good thing when customers need that local support. FIMER have an Australian office in Sydney that can provide these services.

Which FIMER Charger is Right for Me?

For those requiring basic Plug-n-Charge EV charging capabilities, the Stand Alone variant provides a straightforward solution. We would recommend paying the additional $300-$500 for the Future Net model which offers greater connectivity options. 

The Future Net’s ability to integrate with third-party software via OCPP for dynamic charging presents a significant advantage for those desiring greater flexibility and control over their charging ecosystem.
