Specifications
Product Description
The 12V Stationary Battery TAB 7 OPZS 490 | 737Ah is configured with six TAB 7 OPZS 490 cells of 2 V connected in series to obtain 12 V. Its OPzS tubular positive plate technology ensures great stability in float operation, low self-discharge, and exceptional durability, making it ideal for solar banks, telecom, and critical backup. The supply includes the necessary flexible connectors and screws for safe assembly of the set.
Main Features
- Bank capacity: C100 ≈ 737 Ah (C10 ≈ 490 Ah at 12 V).
- Composition: 6× TAB 7 OPZS 490 cells (2 V) with OPzS tubular plate.
- Design life: up to 20 years at 20 °C in float; self-discharge ≈2–3 %/month.
- Translucent SAN container with level markings and cap with ceramic filter.
- 2 V modular format that facilitates expansions and service.
Advantages or Benefits
- Excellent performance in long discharges (C10–C120) typical of PV self-consumption.
- Optimized total cost of ownership due to spaced maintenance and low water consumption.
- Quick visual inspection of the electrolyte for preventive maintenance.
- High reliability for sensitive loads due to its 24/7 voltage stability.
- Possibility to parallel identical banks to increase Ah while maintaining 12 V.
Purpose or Applications
Recommended for off-grid or hybrid photovoltaic installations, UPS with extended autonomy, telecommunications base stations, emergency lighting, and industrial control and monitoring systems.
