for Residential ESS and Off-Grid Solar Systems
Are you an energy storage system integrator, solar installer, or regional distributor seeking a reliable, high-performance battery source to power your clients' projects? As a premier OEM LiFePO4 battery manufacturer, we introduces a commercial-grade selection of custom LiFePO4 battery packs engineered to bridge the gap between high power demands and uncompromising safety.
Whether configuring a sleek residential ESS (Energy Storage System), outfitting a fleet of remote off-grid solar systems, or upgrading high-efficiency solar irrigation setups, this robust product line offers scalable, plug-and-play solutions designed for seamless compatibility with modern hybrid solar inverters.
Features
High-Capacity Cell Architecture
Our high-density cells maximize energy storage within a compact footprint, delivering stable, uncompromised power up to 300Ah to simplify balance-of-system wiring.
Advanced Charging and Discharging Efficiency
With a round-trip efficiency exceeding 95% and support for up to 200A continuous current, these batteries minimize internal resistance to ensure virtually all solar energy gathered is successfully stored and retrieved.
Extended Operational Service Life
Engineered for longevity, the series sustains thousands of deep cycles by keeping internal impedance strictly managed at ≤200mΩ, minimizing thermal stress and long-term capacity fade.
Comprehensive Integrated Protection Performance
An industrial-grade Smart BMS provides automated, real-time protection against over-charging, deep discharging, over-currents, and short circuits to guarantee safe operation with top-tier hybrid inverters.

Versatile Project Application Scenarios
Residential ESS & Home Battery Storage: The 25.6V series operates flawlessly with mainstream hybrid solar inverters to provide smart peak-shaving and reliable home emergency backup power.
RV, Marine & Off-Grid Living: The 12.8V series acts as a lightweight, drop-in replacement for traditional lead-acid banks, delivering high-capacity deep-cycle power for heavy RV and yacht workloads.
Commercial UPS & Solar Irrigation: Engineered with low internal resistance and a 200A maximum discharge rate, these packs easily handle high startup currents for agricultural solar pumps and business backup power.
FAQ
Q: Can these battery packs be connected in series or parallel to expand the total system capacity?
A: Our 12.8V and 25.6V modules support parallel connection up to 4 units to expand capacity.
Q: Can the battery safely handle the high startup inrush currents of induction motors or water pumps?
A: Yes. While its standard continuous discharge is rated at 100A, this specific model supports a maximum continuous discharge current of up to 200A. The BMS architecture allows for a brief surge tolerance to easily absorb the initial inductive peak currents typical of solar irrigation pumps or heavy refrigeration units.
Q: What specific certifications do you provide to clear customs and satisfy local regulatory compliance?
A: Our manufacturing processes and battery designs comply with global standards. We provide complete certification compliance packages, including CE, UN38.3 test summaries, full MSDS reports, and IEC 62619 documentation required for international importation and grid integration.
Q: Lithium batteries are classified as Class 9 Hazardous Materials. Do you have compliance logistics experience?
A: Absolutely. As an experienced LiFePO4 battery factory, we are fully certified in dangerous goods shipping compliance.
Q: Do you offer OEM/ODM customization for regional distribution branding?
A: Yes, we provide full OEM/ODM capabilities. We can customize enclosure metalwork, laser-etch your company branding, configure specific terminal positions, and modify the BMS firmware to match your exact regional market demands and inverter communication preferences.
