Application

Sail Solar battery packs feature an advanced modular design, allowing energy storage systems to consist of multiple independent battery modules. This innovative approach enables seamless expansion, making it easy to increase energy storage capacity to meet your current electricity needs or future energy projects. Our energy storage solutions are designed to meet your evolving needs, providing unparalleled flexibility and adaptability.
If a battery module within the pack fails, simply replace the faulty module; the entire energy storage system must not be shut down. This modular design significantly reduces troubleshooting time and ensures minimal downtime. With minimal maintenance costs and a simplified post-maintenance process, our systems deliver reliability and convenience at every stage.

SAS280Ah LiFePO4 cells are engineered for ultra-long service life: boasting 6,000+ charge-discharge cycles (equating to a 15+ year lifespan with daily operation) and retaining over 80% of nominal capacity after 10 years of use. Featuring a rugged structural design, the cells deliver exceptional resistance to extreme temperatures (-20°C to 60°C) and vibration (compliant with IEC 60068-2-6), rendering them ideal for harsh operating environments such as construction sites and outdoor telecom towers. Adopting non-toxic, non-flammable LiFePO4 chemistry, they completely eliminate fire hazards—an essential safety attribute for enclosed installation spaces.
Integrated 51.2V dedicated Battery Management System (BMS) provides comprehensive protection: it prevents overcharging/over-discharging and short circuits, and enables precise cell balancing with a ±5mV tolerance to further extend the battery’s overall lifespan. The BMS supports real-time monitoring of voltage, current and operating temperature via an on-board digital display or mobile app, and triggers automatic alerts for abnormal conditions to avert battery damage and ensure safe, stable operation.
Certificate
Sail Solar battery delivers unmatched safety and durability. With multi-layer hardware and software protection, ISO 26262 functional safety design, and certifications including UL1973, IEC62619, and UN38.3, we bring automotive-level reliability to your home energy storage.
