Pylontech Fidus PRO 5.12kWh 51.2V LiFePO4 Low Voltage Battery, No Brackets or Cables
The Pylontech Fidus PRO 5.12kWh is a low voltage storage module at 51.2V: it works with Solis low voltage hybrid and AC-coupled inverters, banking solar energy to release it in the evening or during a grid outage. The official compatibility list supplied with the product names the inverter models it is approved for.
Its modular format means you can start with one module and grow later: up to 120 modules in parallel, which is more than 614kWh, so the same battery serves a single house and a commercial installation. The enclosure is IP65 and carries a heating film inside, so the battery operates from -20°C to 55°C and has C5-M corrosion protection — it can live outdoors under cover or in a coastal setting. Cells, modules and BMS are all Pylontech’s own design, with a dual active protection mechanism.
Check what is in the box: this version ships without mounting brackets and without cables, which have to be planned separately according to the installation. Remote monitoring also needs the plug-in WiFi module, included in the separate WiFi kit rather than with the battery. The cells are designed for over 6000 cycles and more than 10 years of service. Installation must be carried out by qualified personnel.
