Modelo: 4 TOPZS 500- Sku: TABBATE063
- Vendor: TAB
Specifications
Product Description
The 48V Stationary Battery TAB 4 TOPZS 500 | 650Ah is a professional 48 V battery bank composed of twenty-four 2 V TOPzS elements with tubular positive plates, microporous separators, and translucent polypropylene containers. Designed for installations with high demand and deep cycles, it stands out for its long service life, low maintenance, and very low self-discharge. Thanks to its 48 V architecture, it reduces DC working currents and optimizes conductor losses, making it a safe choice for solar self-consumption, microgrids, telecommunications, and continuous backup systems.
Main Features
- Configuration: 24× 2 V TAB 4 TOPzS 500 elements (48 V nominal bank).
- Certified capacities of the set: C10 499 Ah · C20 545 Ah · C100 650 Ah (25 °C).
- Reference energy: ≈31.2 kWh at C100 (48 V × 650 Ah; usable energy depends on DoD, temperature, and discharge rate).
- Tubular positive plates, microporous separators, and translucent PP container per cell for visual electrolyte inspection.
- Low internal resistance per cell (≈0.35 mΩ) and theoretical Icc 6005 A → excellent response to peaks.
- Typical life ~1200 cycles and up to 15 years expected with proper use and maintenance.
Advantages or Benefits
- Efficiency at 48 V: lower DC currents, optimized cable sections, and reduced losses.
- Competitive total cost of ownership compared to conventional monoblocs thanks to its durability.
- Simple maintenance: visual inspection of electrolyte level and spaced replenishment.
- Scalability: possibility to expand capacity in parallel while maintaining 48 V.
- Professional integration with DC protections, monitoring, and energy management systems.
Purpose or Applications
Ideal for solar self-consumption at 48 V, hybrid microgrids with generator, telecommunications, control and monitoring centers, long autonomy UPS, solar pumping, and residential or commercial projects with high energy demand.
