Large Battery Energy Storage Systems

Rubix solar batteries deliver performance that does more than hold a charge. Our large battery energy storage systems provide power efficiently, safely, and on demand. This technology is engineered from the ground up to exceed your expectations, pairing advanced lithium-iron-phosphate technology with intelligent controls and modular scalability to match your exact energy needs.

To understand why they outperform conventional systems, it’s worth looking at how these batteries capture, store, and manage energy from the moment it’s generated to the moment you need it most.

How Do Rubix Solar Batteries Work?

  • Capture and store. Solar panels convert sunlight into DC power, which is sent through the inverter to charge the battery. The built-in battery management system (BMS) optimizes charging to protect cell health and maximize efficiency.
  • Manage and balance. Intelligent controls monitor every cell, automatically balancing charge levels to ensure consistent performance and extend lifespan.
  • Deliver on demand. When energy use peaks, rates rise, or the grid goes down, stored power is converted back to AC electricity for seamless supply to your home or business.
  • Scale as needed. Additional battery modules can be added without complex rewiring, expanding capacity as your energy needs grow.

This streamlined process from Rubix large battery energy storage systems turns excess solar energy into a dependable reserve. This reduces your costs and gives you full command over your power. Rubix solar batteries are designed to maximize energy efficiency and reduce reliance on the grid. We make your choice of Rubix solar batteries a simple one. Here’s why:

Ten Reasons Rubix Solar Batteries Are Worth the Investment

  1. High Energy Density in a Compact Footprint
    Our advanced LiFePO₄ chemistry stores more energy per unit volume than lead-acid or older lithium technologies, reducing installation space while increasing usable capacity.
  2. Scalable for Any Demand
    From a single Stack Series unit for residential use to multiple Giga Stack modules for commercial facilities, systems expand seamlessly as your energy needs grow—no full redesign required.
  3. Long Lifespan & Deep Cycle Durability
    Engineered for 6,000+ cycles with minimal degradation, backed by 10-year (Stack Series) and 12-year (Giga Stack) warranties, ensuring decades of reliable service.
  4. Peak Shaving, Load Shifting & Backup Power
    Intelligent algorithms discharge stored power during peak tariff hours to reduce bills, while sub-20ms switchover time ensures uninterrupted supply during grid outages.
  5. Best-in-Class Safety & Thermal Stability
    LiFePO₄ cells are inherently stable and UL‐9540A tested (select models), with safe operating ranges from -20°C to 60°C, plus passive or active cooling for extreme environments.
  6. Advanced Energy Management & Monitoring
    Built-in touchscreen LCDs, closed-loop inverter communications, remote firmware updates, and app-based monitoring provide real-time performance data and long-term optimization.
  7. Broad Inverter Compatibility
    Works with leading hybrid inverter brands (e.g., SMA, SolarEdge, Victron) in both AC- and DC-coupled configurations, allowing flexible integration into new or existing systems.
  8. Rugged, Installation-Ready Design
    NEMA/IP-rated enclosures protect against dust, water, and corrosion, while plug-and-play stacking, enclosed cabling, and caster mobility simplify deployment in any environment.
  9. Sustainable & Cost-Effective
    By maximizing self-consumption of solar power, Rubix solar batteries reduce carbon emissions, lower grid reliance, and lock in savings as energy costs rise.
  10. Future-Proof Investment
    Our modular approach, OTA software upgrades, and compatibility with evolving solar technologies ensure your system grows with you and protects your investment for years to come.
