Specifications
Product Description
The 24V Stationary Battery TAB 12 OPZS 1500 | 2260Ah is a very high-capacity bank configured with twelve TAB 12 OPZS 1500 2 V cells connected in series. This OPzS architecture, based on tubular positive plates, offers great voltage stability in float mode, very low self-discharge, and an extended design life, making it a reference solution for large photovoltaic installations, industrial UPS, and telecommunications. The set is supplied with flexible connectors and connection hardware, allowing for quick assembly with minimal contact resistance.
Main Features
- Bank capacity: C100 ≈ 2260 Ah (C10 ≈ 1500 Ah at 24 V).
- Composition: 12× TAB 12 OPZS 1500 cells (2 V) with OPzS tubular plate.
- Design life: ≈20 years at 20 °C in float mode; self-discharge ≈2–3 %/month.
- Translucent SAN containers with level markings and caps with ceramic filter.
- Reduced maintenance: long water refill intervals and easy visual inspection.
- 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 wiring and protections.
- 24/7 reliability thanks to float stability and the mechanical robustness of the tubular plate.
- Optimized total cost due to its long design life, low water consumption, and spaced maintenance.
- Scalability of the 2 V format: possibility to replace individual cells and expand capacity in parallel.
- Performance in long discharges (C10–C120), ideal for photovoltaic self-consumption and extended backup.
Purpose or Applications
Designed for large 24 V battery banks in off-grid or hybrid photovoltaic systems, data centers and hospitals with high-autonomy UPS, telecommunications base stations, emergency lighting, and industrial, railway, and airport control and signaling systems.
