Its important to know, at this early stage this is still unconfirmed as to exactly how the rebate will work, and it may change to be 30%, however we have reports that the rebate will be paid at between $300-372 per Kwh to the CEC accredited battery installer who submits the installed battery job into the STC system.
The Deye SE-G5.1Pro-B is a cutting-edge high-voltage lithium battery module engineered for superior performance, safety, and scalability in residential and commercial energy storage systems. With a nominal energy of 5.12kWh and a nominal voltage of 51.2V, this robust module is built using advanced LiFePO₄ (Lithium Iron Phosphate) chemistry, ensuring long service life, enhanced safety, and exceptional reliability.
Designed to work seamlessly with a wide range of high-voltage hybrid inverters, the SE-G5.1Pro-B offers a flexible modular design, allowing up to 32 modules to be connected in series for larger systems (up to 163.8kWh total capacity). Its innovative stacked installation design makes expansion simple and tool-free, while maintaining a clean, space-efficient footprint.
Key Features:
Scalable Capacity: Expand easily from a single 5.12kWh unit up to 163.8kWh (32 modules).
Long Life: Over 6,000 cycles at 90% Depth of Discharge (DoD) with excellent performance retention. (approx 8000-9000 at 50%)
High Efficiency: Outstanding round-trip efficiency supports maximum energy savings.
Advanced Safety: Utilizes LiFePO₄ cells, integrated Battery Management System (BMS), overvoltage, overcurrent, and thermal protection.
Flexible Integration: Compatible with Deye’s full range of high-voltage hybrid inverters and many other brands supporting CAN/RS485 communication.
Simple Installation: Stackable design enables easy installation and system expansion without complex wiring.
Wide Operating Range: Supports operation from -20°C to 55°C, with intelligent temperature management.
