SEPLOS 280(S)3.0Y Energy Storage Battery Kit
Professional-Grade DIY Energy Storage Solution • High Safety • Long Cycle Life • Flexible Expansion
Core Features
-
Compatible High-Efficiency Cells
- Designed for EVE 3.2V 280Ah and SEPLOS 3.2V 280Ah LiFePO₄ prismatic cells.
- Grade A cell standards: Self-discharge rate ≤3%/month, initial internal resistance ≤0.23mΩ, cycle life ≥6,000 times (100%DOD, 25°C).
-
Intelligent BMS Management System
- Multi-Protection: Overcharge (57.6V), over-discharge (41.6V), over-current (200A), and wide-temperature (-10°C~50°C for charge/discharge) protection.
- Real-Time Monitoring: Connect to SEPLOS BATTERYMONITOR software via CAN/RS485 for real-time tracking of voltage, current, temperature, and SOC.
- Multi-Protocol Compatibility: Pre-programmed for major inverter brands like Goodwe, Growatt, and Victron.
-
Modular & Scalable Design
- Parallel Capability: Support up to 16 packs in parallel via 8 DIP switches for capacity/power expansion.
- Stackable Structure: Allows stacking up to 4 units for space-efficient installation.
-
Safety-Centric Construction
- Fireproof Insulation: Specialized plastic cell holders meet UL94 V-0 fireproof standards.
- Polarity Protection: Anti-reverse connection design with 8.0mm locking power plugs to prevent misoperation.
-
Plug-and-Play Interfaces
- Communication Ports: RJ45 for RS485/CAN protocols, enabling master-slave communication and inverter integration.
- Status Indicators: 4 LED lights show capacity (25% per LED), with red/green indicators for operation/alarm status.
