The GS-LF51.2-100 is a 5.12kWh wall-mounted lithium iron phosphate battery, the building block of our residential storage range from 2.56kWh (50Ah) to 15.36kWh (300Ah). LiFePO4 chemistry delivers 6000+ cycles – roughly ten times the cycle life of a deep-cycle lead-acid battery – with no maintenance and no acid handling.
Key Features
- Usable capacity: 51.2V 100Ah (5.12kWh) with 90%+ usable energy and stable voltage through discharge.
- Long cycle life: 6000+ cycles, backed by a 5-year warranty.
- Wide series range: 25.6V, 48V and 51.2V models from 50Ah to 300Ah (2.56-15.4kWh).
- Built-in BMS: cell-level protection against over-charge, over-discharge, over-current and temperature extremes, with automatic balancing.
- Scalable: parallel connection of up to 15 modules lets homeowners start small and add capacity later.
- Wide operating window: rated for -20°C to +60°C environments, wall-mounted with integrated display.
Typical Applications
Home backup, solar self-consumption and off-grid living, paired with our 48-51.2V hybrid and off-grid inverters.
Common Pain Points We Solve
- Lead-acid replacement cycles: 6000+ cycles end the two-to-three-year lead-acid replacement loop that generates warranty complaints.
- Indoor safety concerns: LiFePO4 chemistry with cell-level BMS protection is the safe choice for living-space installations.
- Installer compatibility questions: the 48-51.2V range works with all mainstream hybrid inverters, and we confirm protocol matching before shipment.
- Growing customer needs: parallel expansion to 15 modules lets your customers start with one unit and scale – repeat business without re-engineering.
