Specifications
Product Description
The 12V Stationary Battery TAB 12 OPZS 1500 | 2260Ah is a very high-capacity bank built from six TAB 12 OPZS 1500 2 V cells connected in series. This configuration with OPzS tubular positive plates offers maximum robustness for continuous float operation, very low self-discharge, and excellent voltage stability, ensuring reliable energy for large-scale solar projects, industrial UPS, and telecommunications. The set is supplied with flexible connectors and appropriate hardware, simplifying assembly and guaranteeing low-resistance connections.
Main Features
- Bank capacity: C100 ≈ 2260 Ah (C10 ≈ 1500 Ah at 12 V).
- Composition: 6× TAB 12 OPZS 1500 cells (2 V) with OPzS tubular positive plate.
- Design life: up to 20 years at 20 °C in float; self-discharge ≈2–3 %/month.
- Reduced maintenance: long water refilling intervals thanks to OPzS design.
- Translucent SAN containers with level markings and cap with ceramic filter.
- Dimensions and weight per cell: 277 × 206 × 536 mm; ≈74 kg (wet).
Advantages or Benefits
- Maximum autonomy per string: reduces the number of parallel banks and simplifies installation.
- Optimized total cost of ownership due to its durability, low self-discharge, and extended maintenance intervals.
- Safety and control: direct visual inspection of electrolyte level and float stability for sensitive loads.
- Modularity: 2 V format facilitates expansions, replacements, and service without stopping the installation.
- Performance in long discharges (C10–C120), ideal for photovoltaics and extended backup.
Purpose or Applications
Recommended for large off-grid or hybrid photovoltaic installations (12/24/48 V with series/parallel), data centers and hospitals with long autonomy UPS, telecom base stations, emergency lighting, and industrial, railway, and airport control and signaling systems.
