Sorein A4 4234wh Lfp Stackable Battery Home Energy Storage

The Sorein A4 4234Wh LFP Battery delivers reliable, scalable energy storage for homes seeking backup power or solar optimization. Built with advanced Lithium Iron Phosphate (LFP) technology, this stackable battery ensures long cycle life, enhanced safety, and seamless integration with existing solar systems. Ideal for reducing grid dependence, it adapts to growing energy needs with modular expansion—up to 8 units for extended capacity.

⚡ Why Choose the Sorein A4 for Home Energy Storage?

Designed for durability and efficiency, the Sorein A4 stands out with its 10,000+ cycle lifespan, outperforming traditional lead-acid batteries while requiring minimal maintenance. Its compact, wall-mounted design saves space without compromising performance, making it a versatile choice for urban or off-grid homes. The built-in Battery Management System (BMS) monitors voltage, temperature, and charge levels in real time, ensuring optimal operation and longevity.

Compatibility is another key advantage. The Sorein A4 integrates effortlessly with major inverters like Victron, SMA, and GoodWe, offering plug-and-play convenience for both new and retrofitted solar setups. With a 95% depth of discharge (DoD), users can utilize nearly all stored energy, maximizing cost savings and sustainability.

📊 Key Specifications & Practical Use

• 4234Wh capacity per unit (stack up to 8 for 33.8kWh total)
• LFP chemistry: 10,000+ cycles at 80% DoD, 10-year lifespan
• 100A continuous discharge current; 200A peak for high-demand appliances
• Operating range: -20°C to 50°C (-4°F to 122°F) for all-climate reliability
• Modular design: Add units as energy needs grow, no system overhaul required
• UL1973, CE, and UN38.3 certified for safety and compliance

Daily use is straightforward: pair with a compatible inverter to store excess solar energy during the day and deploy it during peak hours or outages. The Sorein A4’s silent operation and zero emissions make it suitable for indoor installation, while its IP20 rating protects against dust ingress for garage or basement setups.

🌱 Sustainable Energy, Long-Term Savings

Beyond backup power, the Sorein A4 reduces reliance on fossil fuels by storing renewable energy for later use, lowering carbon footprints and utility bills. Its LFP composition eliminates cobalt, a conflict mineral, while the extended lifespan minimizes e-waste. For homeowners prioritizing both economic and environmental benefits, this battery offers a future-proof solution with rapid ROI—especially in regions with time-of-use pricing or frequent blackouts.
