ROCKSOLAR GSL-R Series 20kWh–61.44kWh High Voltage LiFePO4 Battery System

What it does: High-voltage, large-capacity energy storage for residential, commercial, and industrial solar systems — pairs with hybrid inverters for backup power, solar self-consumption, and microgrid applications.

Key specs:

• Capacity: 20kWh–61.44kWh
• Chemistry: LiFePO4 | Voltage range: 204.8V–614.4V
• Cycle life: 6,500+
• Expansion: up to 32 units in parallel
• Installation: floor-standing modular cabinet

Built for: Whole-home backup, commercial ESS, industrial energy storage, solar battery systems, microgrids, demand charge reduction, off-grid projects

Why it matters:

• High-voltage architecture (up to 614.4V) = lower current losses, better inverter efficiency, lower balance-of-system costs
• 6,500+ cycles = long service life with minimal degradation
• Integrated BMS = overcharge, over-discharge, overcurrent, temperature protection, and cell balancing
• Modular cabinet design = easy expansion, professional install, simplified maintenance
• Scalable up to 32 units = grows from residential to large commercial scale

Certifications: UL1973, UL9540, UL9540A — meets North American safety standards
