5-30KWH Stacked Lithium Batteries
Power & Capacity Performance: Operates at a nominal 48V, with a safe range of 45V (discharge cutoff) to 57.6V (charge cutoff), ensuring stable power delivery for devices like home appliances, small industrial tools, and solar system inverters. The 5kWh model handles 1–2kW loads for 3–5 hours (e.g., a 1.5kW air conditioner for 3+ hours), while the 10kWh variant powers 2–3kW systems for 5–10 hours (sufficient for a small business during short outages). Both support continuous discharge currents of 25A (5kWh) and 50A (10kWh), with peak surges up to 100A, making them suitable for occasional high-demand devices like power tools or mini-fridges.
Safety & Longevity: The integrated BMS provides multi-layer protection, including overcharge safeguards (cutoff at 57.6V), over-discharge prevention (cutoff below 45V), and defenses against overcurrent (50A continuous for 5kWh, 100A for 10kWh) and short circuits. It regulates temperature from -20°C to 60°C, with automatic shutdown at 65°C to prevent overheating. Active cell balancing ensures uniform charge across 16 series-connected lithium cells (3.2V each), preventing uneven aging and maximizing capacity retention. This, combined with lithium chemistry, delivers 5,000+ deep cycles at 80% depth of discharge-8–10x more than lead-acid-with a 12–15 year lifespan and zero maintenance (no watering or acid checks).
Design & Scalability: Encased in a fire-retardant, IP65-rated housing, the battery resists dust, rain, and light vibration, suitable for indoor, garage, or covered outdoor installations. Its compact size (e.g., 5kWh module: 450×300×600mm, ~40kg) saves 60% space compared to lead-acid equivalents, fitting easily in tight spaces. The modular stacking design allows plug-and-play parallel expansion via quick-connect terminals, letting users scale capacity up to 50kWh by adding more units-ideal for growing off-grid homes or businesses.
Efficiency & Compatibility: With 94% round-trip energy efficiency, it minimizes energy loss, outperforming lead-acid (80% efficiency) and reducing reliance on grid or generator power. It integrates seamlessly with MPPT solar charge controllers and inverters (Victron, Renogy) via standard RS485 communication, enabling real-time monitoring of SOC, voltage, and temperature through a built-in LCD or smartphone app. This ensures easy integration into existing solar setups or backup systems, making it a user-friendly choice for both residential and small commercial use.
