Introducing the SJY 300Ah 51.2V LiFePO4 Battery Pack — a high-performance 15 kWh energy storage solution built for 48V solar storage, off-grid homes, and reliable daily power. Designed with LiFePO4 chemistry, this 51.2 V battery delivers long life, safety, and stable energy supply to keep essentials running when sunlight is scarce. Its compact 390×270×800 mm footprint and 120 kg weight make it suitable for residential installations without sacrificing performance.

Key to effortless energy management is the smart connectivity. The battery features a smart BMS with Bluetooth and Wi‑Fi support, letting you monitor state of charge, voltage, current, and temperature in real time from your smartphone. Communication versatility is enhanced by CAN and RS485 protocols, enabling seamless integration with more than 20 inverter brands for a smooth plug‑and‑play setup. You can also choose the inverter protocol via the Bluetooth app or the battery’s display, making configuration quick and user-friendly.

Designed for scalable storage, these 15 kWh modules can be connected in parallel to achieve larger capacities (for example 30 kWh, 45 kWh, 50 kWh and beyond). Remember that these batteries cannot be connected in series, so parallel assembly is the recommended approach for increasing storage while maintaining safe operation.

Safety and quality are built in. The battery is CE, UN38.3 and MSDS certified, and housed in a robust enclosure to protect internal components. For enhanced safety, it includes an aerosol-based fire suppression device that rapidly reacts within 0.2 seconds at critical temperatures to help prevent battery ignition. This combination of advanced protection and rigorous testing provides peace of mind for home and commercial energy systems.
