About the Felicity Solar FLS48050SG1M3 51.2V 2.56kWh LiFePO4 Battery

The Felicity Solar FLS48050SG1M3 is a floor-mounted LiFePO4 battery module that stores 2.56kWh, built from 50Ah of cells at a nominal 51.2V in the 1P16S arrangement its designation records as 150/102/[1P16S]M/-10+50/95. It weighs 93.0 kg net and 112.0 kg gross in its shipping carton, and is rated beyond 6000 cycles. Those two weights are what separate this model from the other 51.2V modules beside it, so quote the FLS48050SG1M3 by weight when you plan delivery, lifting and floor loading. Depth of discharge is ≥95%, which keeps the daily working reserve close to the whole 2.56kWh rather than a fraction of it. The module holds a 44.8-57.6V system window, charges between 0°C and 55 °C, discharges from -20°C, and should be stored between 0°C and +35°C at an altitude below 2000m. The packed carton measures 642 x 462 x 337 mm. Certified to CE-EMC and IEC 62619, it carries a 5 Years warranty.

Frequently Asked Questions

How much energy does the Felicity Solar FLS48050SG1M3 store?

2.56kWh. The FLS48050SG1M3 holds 50Ah of LiFePO4 cells at a nominal 51.2V, and its depth of discharge of ≥95% means almost all of that 2.56kWh is available each cycle rather than a fraction of it.

How much does the FLS48050SG1M3 weigh?

93.0 kg net. Packed for transport the FLS48050SG1M3 weighs 112.0 kg gross in a carton of 642 x 462 x 337 mm, so plan mechanical lifting and check the floor loading before it arrives — it is a floor-mounted unit.

How long will the FLS48050SG1M3 last?

More than 6000 cycles is the rated cycle life of the FLS48050SG1M3; its depth of discharge is a separate rating at ≥95%. The module is certified to CE-EMC and IEC 62619 and is supplied with a 5 Years warranty.

What voltage and temperature range does the FLS48050SG1M3 need?

44.8-57.6V is the system operating window of the FLS48050SG1M3, around a nominal 51.2V. Charge it between 0°C and 55 °C, discharge from -20°C to 55 °C, store it between 0°C and +35°C, and install below 2000m.
