Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- 5.12 kWh to 40.96 kWh in one stack: Begin with one 100 Ah, 5.12 kWh module and add up to eight in parallel; the FLS48100SG2 stays at 51.2 V whichever size you build.
- ≥6000 cycles, with ≥95% depth of discharge: The LiFePO4 cells are rated for ≥6000 cycles with a depth of discharge of ≥95%, so nearly all of the 40.96 kWh is usable every day.
- 400 A continuous, 800 A peak for 15 seconds: Continuous charge/discharge climbs 60, 120, 180, 240, 300, 360, 400 and 400 A as modules are added, with a 15-second peak ladder from 100 A to 800 A.
- S16 BMS reporting over RS485 or CAN: The S16 battery management system holds the FLS48100SG2 inside 44.8~57.6 V, floats at 57.6 V and cuts off at 48 V, reporting over RS485 or CAN.
- IP21 cabinet with breaker, fuse and under-voltage protection: A built-in smart BMS, breaker and fuse guard the IP21 enclosure, which carries under-voltage protection and runs at 5% ~ 95% relative humidity up to 2000 m.
- 46 kg modules, 414 kg fully stacked: Every 600 x 450 x 180 mm module weighs 46 kg and the complete 600 x 1620 x 450 mm FLS48100SG2 weighs 414 kg, wall-mounted or floor-mounted.
Frequently Asked Questions
How much energy does the FLS48100SG2 store?
5.12 kWh to 40.96 kWh. One 100 Ah module holds 5.12 kWh at 51.2 V, and the FLS48100SG2 takes up to eight modules in parallel for 40.96 kWh. Because the depth of discharge is ≥95%, almost all of that energy is usable.
What charge and discharge current does the FLS48100SG2 support?
400 A maximum. Charging runs at 60 A per module up to a 400 A ceiling, and the continuous charge/discharge ladder is 60, 120, 180, 240, 300, 360, 400 and 400 A as modules are added, with a 15-second peak of 100 A to 800 A.
What are the dimensions and weight of the FLS48100SG2?
600 x 1620 x 450 mm and 414 kg for the complete stack. Each battery module and the control module measure 600 x 450 x 180 mm and weigh 46 kg, and the package measures 712x562x298mm. Wall-mounted and floor-mounted installation are both supported.
Where can the FLS48100SG2 be installed?
0°C to +55°C for charging and -20°C to +55°C for discharging. The IP21 enclosure suits indoor rooms at 5% ~ 95% relative humidity and altitudes of ≤2000m, and the FLS48100SG2 should be stored between 0°C and +35°C.
