Three Phase Inverters – Datamanager Card Retrofit for Symo/Eco

The Fronius Datamanager Card Retrofit is a retrofit Plug-In card designed for all SnapINverter models, including Primo and Symo. With this network-compatible datalogger, PV system data and archived information are automatically transmitted to the portal. This provides users with constant updates on the performance of the inverters and overall PV system, accessible through a web browser directly or via the internet.

The Fronius Datamanager Card is the communications center for Fronius inverters and all of its applications. 

  • Fully integrated datalogging
  • 10 year warranty
SKU 4.240.038.Z Categories ,


  • Integrated Internet Connectivity & Data Communication

The inverter has a fully integrated data logging system equipped with WLAN, Ethernet, energy management and a web server. Without extra cabling, it connects to the internet for an overview of the PV system’s functions.

  • SuperFlex Adaptable Solar System Design 

Choose exactly how to design your PV system. The inverter’s unique SuperFlex Design has two MPP trackers combined with a high system voltage and wide DC input voltage range. This means the unit can adapt to various roof orientations and sun conditions — well-suited to any PV system configuration.

  • PV Point

The PV Point is an integrated basic backup power supply feature that is found in some inverters, including the Fronius Datamanager Card Retrofit. This feature allows the inverter to supply electricity during grid outages, drawing energy from the solar panels to keep the essential loads running.

  • Dynamic Peak Manager: Innovative MPP Tracking

Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point (GMPP), even in partial shade. The innovative MPP tracking algorithm adapts its behaviour when finding the optimal operating point for your inverter.

  • Multi Flow Technology

With Multi Flow Technology, the Fronius Datamanager Card Retrofit enables a wide range of energy flows to occur in parallel. This allows energy from the modules and battery to be used simultaneously for domestic purposes. Furthermore, energy from the modules can also be fed into the battery and the in-house network concurrently, leading to maximum efficiency. Additionally, the battery can be charged from both the DC and AC sides, making the inverter an ideal choice for AC-coupled retrofitting. The Fronius Datamanager Card Retrofit expertly manages these energy flows to achieve the highest possible degree of self-sufficiency.

  • Active Cooling Technology

Powerful fans regulate air circulation inside the inverter, cooling the temperature of power electronics before they can overheat. This maintains the service life of the device, reducing maintenance costs.

  • Full Power Backup

In the event of a grid outage, this powerful inverter can supply the entire household, including both 1 phase and 3 phase devices, with uninterrupted electricity. This is an incredibly valuable feature for those seeking a comprehensive backup power solution.

  • International Safety Standards

All Fronius inverters meet international safety standards, including automatic shut-down in the event of grid failure. The inverter comes with a built-in surge protection device and has an IP20 rating, meaning it’s protected from dust build-up.
