Flexible Expansion — Parallel Up to 15 Units

Highly scalable system design supports parallel connection of up to 15 units, including mixed use of new and old batteries and optional lead-acid battery parallel configurations.

Lithium Iron Phosphate Battery — High Energy & Long Lifespan

LiFePO₄ cells deliver ≥5000 cycles, excellent thermal stability, high discharge rate, and up to 95% depth of discharge for greater usable capacity and longer lifespan.

Multi-Level Protection — Intelligent BMS Management

Advanced BMS provides real-time monitoring of voltage, current, temperature, and cell status, ensuring safety and stability through multiple layers of protection.

Reliable Home Backup — Power Security in Every Critical Moment

Supports off-grid operation during outages or in areas without electricity, enabling continuous power supply and self-sufficient energy usage.

Extreme Temperature Resistance — Stable Operation in Harsh Climates

Operates from –10°C to +50°C with an automatic low-temperature heating system that maintains optimal performance below 0°C.

Clear System Working Principle

Solar panels, grid power, and the battery pack work together through the inverter to supply stable energy for household appliances.
