The Felicity Solar FLS48050SG1M2 is a floor-mounted LiFePO4 battery module built from 50Ah of cells at a nominal 51.2V for 2.56kWh of module energy. It weighs 62.0 kg net and 76.0 kg gross in its shipping carton, holds a 44.8-57.6V system window, and is rated beyond 6000 cycles, with depth of discharge rated separately at ≥95%. Those two weights are what identify this exact code rather than a neighbouring suffix, so read the trailing M2 on the nameplate before ordering and quote the 76.0 kg gross figure when you arrange delivery and lifting. Its battery designation reads 150/102/[1P16S]M/-10+50/95. Charging is specified from 0°C to 55 °C and discharging from -20°C to 55 °C; store the module between 0°C and +35°C and install it below 2000m. The shipping carton measures 642 x 462 x 337 mm, and because installation is floor-mounted no wall has to carry the 62.0 kg unit. The module is certified to CE-EMC and to IEC 62619, and it ships with a 5 Years warranty. We are an authorised Felicity Solar distributor and will confirm the M2 suffix on your order.

62.0 kg net, and 76.0 kg gross once it is inside its shipping carton of 642 x 462 x 337 mm. Those two figures belong to the FLS48050SG1M2 alone, so plan mechanical lifting and check the floor loading before delivery — the unit is floor-mounted.
2.56kWh of module energy, from 50Ah of LiFePO4 cells at a nominal 51.2V. With a depth of discharge of ≥95%, nearly all of that 2.56kWh is available each cycle rather than a fraction of it.
More than 6000 cycles; depth of discharge is a separate rating at ≥95%. The FLS48050SG1M2 is certified to CE-EMC and IEC 62619, and it is supplied with a 5 Years warranty.
44.8-57.6V is the system operating window, around a nominal 51.2V. Charge the module 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.
