Specifications
Product Description
The 24V Stationary Battery TAB 7 OPZS 490 | 737Ah is configured with twelve TAB 7 OPZS 490 cells of 2 V connected in series to obtain 24 V. The OPzS tubular positive plate technology ensures high stability in float operation, low self-discharge, and a prolonged design life, ideal for solar banks, telecommunications, and critical backup. The set is supplied with flexible connectors and screws for quick, safe, and low-resistance assembly.
Main Features
- Bank capacity: C100 ≈ 737 Ah (C10 ≈ 490 Ah at 24 V).
- Composition: 12× TAB 7 OPZS 490 cells (2 V) with OPzS tubular plate.
- Design life: up to 20 years at 20 °C; self-discharge ≈2–3 %/month.
- Translucent SAN container with level markings and cap with ceramic filter.
- Dimensions/weight per cell: 166 × 206 × 536 mm; ≈39 kg (wet).
Advantages or Benefits
- Excellent performance in long discharges (C10–C120), typical in photovoltaics.
- Total cost of ownership optimized by spaced maintenance and low self-discharge.
- Simple visual inspection of the electrolyte for preventive maintenance.
- 2 V modular format that facilitates expansions, service, and cell-by-cell replacements.
- 24/7 voltage stability that protects loads and sensitive electronics.
Purpose or Applications
Suitable for off-grid or hybrid photovoltaic systems at 24 V, UPS with extended autonomy, telecommunications base stations, emergency lighting, and industrial control and monitoring systems.
