Lithium Energy Storage System Pylontech FORCE-L

Solar Lithium storage system
48 VDC, up to 24.86 kWh (L1)
48 VDC, up to 14.21 kWh (L2)

The Pylontech FORCE-L systems are battery storage systems for home applications based on lithium iron phosphate batteries, some of the new energy storage products developed and manufactured by Pylontech. They can be used to support reliable power supply for various types of appliances and systems. FORCE-L systems are particularly suitable for application scenes where high power, limited installation space, limited load capacity and long life are required. They have a modular structure and can be easily installed and expanded by plugging them into each other.

The Pylontech FORCE-L1 and FORCE-L2 storage systems consist of lithium iron phosphate (LiFePo4) accumulators with a battery management system, or BMS for short, which constantly monitors the status of the accumulators down to the individual cells and protects them from overcharging, overvoltage and overtemperature, among other things.

In this way, the BMS prevents premature failure of the batteries due to environmental influences or incorrect use.
The modular design allows the individual configuration of the storage system to the required capacity by simply interconnecting the desired number of modules.
