Pylontech Fidus Plus PRO 16kWh 51.2V Low Voltage Heated LiFePO4 Battery
The Pylontech Fidus Plus PRO 16kWh is a low voltage storage battery in a single enclosure: 16.08kWh at 51.2V, built for a domestic solar installation or a small business. It collects what the array produces while the sun is up and releases it when the light fades. The PRO version carries built-in heating, so it also works in cold rooms and exposed installations.
The declared depth of discharge is 100%: all 16.08kWh of nominal energy are usable, with no reserve to hold back. The charge and discharge rate is 0.67C, more than 10kW in both directions, so the battery handles fast charging through the middle of the day as readily as heavy evening loads. Up to 20 units can run in parallel, which means the same model covers a house and grows into business-scale storage.
Installation is flexible: wall mounted or floor standing, depending on the space available. State of charge is read on the integrated display or remotely, since the battery carries both Bluetooth and Wi-Fi. The cells are lithium iron phosphate and the declared life is 8000 cycles. Inverter compatibility must be checked against the official Pylontech documentation; installation and commissioning must be carried out by qualified personnel.
