Frequently Asked Questions

Q: What is the difference between LFP and NMC batteries?
A: LFP (Lithium Iron Phosphate) offers superior safety, longer cycle life (6000+ vs 3000-4000 cycles), and better thermal stability compared to NMC (Nickel Manganese Cobalt) batteries. LFP has no risk of thermal runaway, operates safely at higher temperatures, and contains no toxic heavy metals. While NMC has slightly higher energy density, LFP's safety and longevity make it the preferred choice for residential applications.
Q: Can I expand the battery capacity later?
A: Yes! The LS-B10 features modular expandability—simply stack up to 4 units (40kWh total) as your energy needs grow. Each unit connects via CAN bus and automatically synchronizes with existing modules. No rewiring or inverter replacement required. We recommend planning for future expansion during initial installation to ensure adequate wall space and electrical capacity.
Q: How long does the battery last before needing replacement?
A: With 6000+ cycles at 80% DoD, the LS-B10 provides over 16 years of daily cycling before reaching 80% of original capacity. For typical residential use (1 cycle per day), expect 15-20 years of service life. The battery continues functioning beyond 6000 cycles—capacity gradually decreases to 70-75% over the next 5-10 years. GUANGXI offers a 10-year warranty covering 70% capacity retention.
Q: Is the battery safe for indoor installation?
A: Absolutely. LFP chemistry is the safest lithium battery technology available—no risk of thermal runaway, fire, or explosion. The LS-B10 includes multi-layer BMS protection, thermal management, and IP65 weatherproof enclosure. Certified to UL 9540 (energy storage systems) and UL 1973 (stationary batteries), meeting the strictest safety standards. Suitable for installation in garages, utility rooms, or outdoor walls. Fanless design ensures silent operation (<30dB).
Q: What happens if the battery runs out during a power outage?
A: If the battery depletes to minimum SOC (State of Charge, typically 10-20%), the system automatically shuts down to protect battery health. Once grid power returns or solar generation resumes, the battery recharges automatically. To extend backup duration, the intelligent BMS can prioritize critical loads (refrigerator, lights, internet) and shed non-essential loads (pool pump, EV charger). For extended off-grid capability, consider upgrading to 20-40kWh capacity.
Q: Can the battery work without solar panels?
A: Yes! The LS-B10 can operate in grid-charging mode without solar panels. This is ideal for peak-valley arbitrage applications—charge from the grid during off-peak hours (low electricity rates) and discharge during peak hours (high rates). However, combining with solar panels maximizes economic benefits by storing free solar energy instead of paying for grid electricity. We recommend at least 5-8kW of solar capacity for optimal performance.
