Specifications
Product Description
The 48V Stationary Battery TAB 5 OPZS 350 | 527Ah is a high-performance bank configured with 24 TAB 5 OPZS 350 2 V cells connected in series to obtain 48 V. Its OPzS tubular positive plate technology offers great stability in float operation, very low self-discharge, and an extended design life, making it an ideal solution for off-grid solar installations, telecommunications, UPS systems, and industrial control. It is supplied with the necessary flexible connectors and hardware to complete the interconnection between cells with minimal resistance and maximum reliability.
Main Features
- Bank capacity: C100 ≈ 527 Ah (C10 ≈ 350 Ah at 48 V).
- Architecture: 24× 2 V OPzS cells (tubular plate) connected in series.
- Design life: ≈20 years at 20 °C in float; self-discharge ≈2–3 %/month.
- Reduced maintenance: low water consumption and long refill intervals.
- Translucent SAN container with level markings and cap with ceramic filter.
- Modular 2 V format that facilitates group replacements and expansions.
Advantages or Benefits
- 24/7 voltage stability that protects electronics and sensitive loads.
- Excellent performance in long discharges (C10–C120) typical of PV self-consumption.
- Quick visual inspection of the electrolyte and level control in seconds.
- Lower total cost of ownership thanks to its durability and spaced maintenance.
- Quick installation with included connectors and hardware, ensuring low-resistance contacts.
Purpose or Applications
Especially suitable for 48 V banks in off-grid or hybrid photovoltaic installations, data centers/UPS with extended autonomy, telecommunications base stations, emergency lighting, and SCADA systems for industrial control and monitoring.
