Description

The Felicity FLS48100SG2 20.48kWh is the ultimate powerhouse for demanding households and businesses. If you need large amounts of electricity for heat pumps, multiple electric vehicles, or a very high level of self-consumption, this XXL storage system gives you the perfect foundation. Become almost completely independent from the public power grid and use your harvested solar energy day and night.

Your Advantages at a Glance

Maximum fire safety: Each of the four modules is equipped with a self-contained aerosol fire suppression system that reacts instantly in an emergency, without any external power supply.
Intelligent system control: The smart control module with LCD display perfectly manages the three expansion modules and shows you the current system status at all times.
Future-proof modularity: With four modules you already have an enormous capacity, but the system can be expanded to up to eight units in parallel as your needs grow.
High compatibility: Standardized RS485 and CAN interfaces ensure smooth communication with leading inverters from manufacturers such as Deye, Growatt, or Victron.
Long-lasting quality: The proven lithium iron phosphate cells (LiFePO4) guarantee thousands of charge cycles and an extremely long service life.

Full Control Over Your Energy

A storage system of this size permanently changes your electricity bill. The enormous capacity of 20.48 kWh not only absorbs daily consumption peaks but also safely gets you through days with little sunshine. Thanks to an excellent depth of discharge, you can use almost the entire battery capacity. The intelligent battery management system (BMS) ensures perfect cell balancing across the entire battery tower. Installation is very user-friendly thanks to the included rolling base: the four modules are simply and securely stacked on top of one another – no heavy wall mounting required.
