Specifications
Product Description
The 48V Stationary Battery TAB 12 OPZS 1500 | 2260Ah is the highest capacity bank in the TAB OPzS series at 48 V. It is built from twenty-four 2 V cells (model 12 OPZS 1500) connected in series, ensuring a stable voltage of 48 V with a huge energy reserve. The OPzS tubular positive plate technology offers excellent retention of active material, very low self-discharge, and a design life of up to 20 years in float, essential qualities for large-scale solar installations, telecommunications, and industrial backup systems where service continuity is critical. The set is supplied with flexible connectors and hardware to complete the interconnection between cells with minimal contact resistance.
Main Features
- Massive capacity: C100 ≈ 2260 Ah (C10 ≈ 1500 Ah) at 48 V for extended autonomy.
- Robust architecture: 24× 2 V cells with OPzS tubular plate and translucent SAN container.
- 24/7 reliability: stable voltage in float and self-discharge ≈2–3 %/month at 20 °C.
- Reduced maintenance: low water consumption and immediate visual control of electrolyte level.
- Professional installation: supplied with connectors and screws; 2 V format facilitates cell-by-cell servicing.
Advantages or Benefits
- Maximum autonomy per string: reduces the number of parallels, simplifies protections, and improves system efficiency.
- Optimized total cost: long service life, extended maintenance intervals, and replaceable cell components.
- Safe operation: voltage stability for sensitive equipment (SCADA, telecom, servers, drives).
- Performance in long discharges (C10–C120), ideal for photovoltaic self-consumption and extended backup.
- Scalability: possibility to parallel identical banks to increase Ah while maintaining 48 V.
Purpose or Applications
Designed for large 48 V banks in off-grid or hybrid solar installations, data centers and hospitals with high-autonomy UPS, telecommunications base stations, critical infrastructure, emergency lighting, and industrial control and monitoring systems in demanding environments.
