Photovoltaic Solar Panel String Inverter

String inverter

System on Module

A business unit within the PRETTL Energy Division, REFU Elektronik provides the full value chain in the hybrid energy space across various energy applications from Gensets to Power Electronics with PV and storage inverters.

The Application

With maximum power density, REFU solar panel string inverters combine installation flexibility, serviceability and connectivity in a revolutionary design. PHYTEC hardware based on Freescale/NXP Power Architecture devices drives the REFUsol 12kW – 24kW Power Class String Inverters, which offer industry-best top efficiency of 98.2%.

The Solution

The small form factor of the phyCORE-MPC5200B Tiny System on Module made it an ideal fit for REFU Elektronik. PHYTEC designed a completely custom board by combining the compact circuitry of the SOM into a single PCBA with dedicated I/O connectors.


Enabling Products and Services from PHYTEC

  • Hardware: Custom configuration of the phyCORE-MPC5200B Tiny System on Module in first generation inverters
  • Custom Hardware Design:  Development and production of a “flat” single PCBA combining MPC56K processor circuitry with I/O circuitry and connectors for second generation inverters, including ICT test development
