Battery Type and Capacity | Emergency backup, outdoor activities | - Industry: Lead-Acid (500Wh) - Base: Lithium (450Wh) ▲10% lighter (ISO 17619) - Advanced: Lithium (10000Wh) ▲222% capacity (IEC 62619) | Lithium offers lighter weight and 2000+ cycles lifespan. Advanced supports massive energy storage. | Advanced model’s higher cost; Base’s capacity may limit long-term use. |
Nominal Voltage & Power Output | Powering appliances (fridges, tools) | - Industry: 12V, 800W (IEC 60038) - Base: 12.8V, 1000W ▲25% power (IEC 60038) - Advanced: 12.8V, 1000W (same power, extended runtime) | Supports simultaneous use of high-power devices. Advanced runs devices longer. | Advanced requires thicker cables for high loads. |
Solar Charging Efficiency | Off-grid camping, solar-dependent setups | - Industry: PWM (85% efficiency) - Base: MPPT (95% efficiency) ▲10% efficiency (IEC 61215) - Advanced: MPPT (1000W input) | MPPT charges 20% faster from solar panels. Advanced handles larger solar arrays. | PWM systems are cheaper but less efficient. |
Weight & Portability | Hiking, mobile emergency response | - Industry: 20kg (Lead-Acid) - Base: 10kg ▲50% lighter (ISO 714) - Advanced: 100kg (Lithium) ▲900% capacity but 900% heavier | Base is backpack-friendly. Advanced suits stationary use. | Advanced’s weight limits portability. |
Warranty & Durability | Long-term investments, commercial use | - Industry: 2 years - Base: 3 years ▲50% longer (IEC 62619) - Advanced: 3 years (same as Base) | Extended warranty reflects reliability. Both tiers offer robust build quality. | None for Base/Advanced. |
Safety Features | Medical equipment, critical applications | - Industry: Basic overcharge protection - Base: Overcharge/overcurrent/short-circuit protection ▲ added safety (IEC 60950) - Advanced: Same + thermal management ▲ improved cooling | Enhanced safety for sensitive equipment. Advanced prevents overheating. | Advanced features may increase cost. |
