SOFAR Power All

SOFAR Power All is a series of modular, integrated single-phase hybrid inverters with DC‑coupled energy storage. It offers flexible, expandable battery capacity, delivering maximum usable energy through optimized pack design and exceptionally low self‑consumption in sleep mode.

Key features of SOFAR Power All:

  • Modular, integrated design with DC‑coupled energy storage.
  • Flexible, expandable battery capacity from 5 kWh up to 30 kWh.
  • Compatible with high‑current photovoltaic panels and 2 independent MPPT inputs.
  • Very short switchover time to critical loads (<10 ms).
  • Exceptionally low battery self‑consumption in sleep mode.
  • Capable of off‑grid operation with peak power up to 9000 VA.

Who is this a good choice for?

The SOFAR Power All system is ideal for homeowners and small businesses seeking a reliable, flexible solution for storing solar energy. With expandable capacity, it’s a future‑proof option that can grow with the user’s needs. Low energy consumption and fast switchover times make it suitable for applications that require continuous power, such as critical loads.
