48V 51.2V 15kWh 300Ah Solar Lithium Batteries: The Ultimate Home Energy Storage Solution

In an era of rising energy costs and grid instability, the Home Energy Storage Battery has transitioned from a luxury to a household necessity. Our 51.2V 15kWh 300Ah LiFePO4 Power Station is engineered to provide the ultimate energy independence. Utilizing the safest Lithium Iron Phosphate (LiFePO4) chemistry, this high-capacity system is designed to integrate seamlessly with your solar array, ensuring your home remains powered through every sunset and every blackout.

Precision Engineering: High-Performance Specifications

At the core of this system is a robust 16S (16 Series) configuration of Grade-A 300Ah LiFePO4 cells. While many standard systems offer 100Ah or 200Ah, our 300Ah model delivers a massive 15.36kWh of usable energy in a single unit.

• Voltage Architecture: Nominal 48V with a working voltage of 51.2V, making it perfectly compatible with the world’s leading off-grid and hybrid inverters (such as Victron, Growatt, and Deye).
• Active Balance Technology: Unlike passive balancing systems that dissipate energy as heat, our Active Balance BMS actively transfers charge from higher-voltage cells to lower-voltage ones. This significantly reduces cell-to-cell variance, maximizes usable capacity, and extends the battery’s lifespan by up to 20%.
• DIY-Friendly Design: Housed in a durable, modular DIY Battery Box, this system allows for easy maintenance and future scalability, giving users and installers full control over their energy infrastructure.

Versatile Applications: Beyond Basic Backup

The Home Energy Storage Battery is no longer just for emergencies. Its high energy density and high discharge capability make it ideal for:

• Solar Self-Consumption: Store excess energy generated during the day to power your home at night, effectively reducing your reliance on the utility grid to zero.
• Peak Shaving: Automatically discharge during high-tariff “peak” hours to slash your electricity bills.
• Uninterruptible Power Supply (UPS): With millisecond-level switching, protect sensitive electronics and home appliances from power surges and outages.
• Off-Grid Living: Provide consistent, heavy-duty power for remote cabins, sustainable farms, or high-end RV/Marine setups that require 48V high-capacity storage.
