- Vendor: TAB
Specifications
Product Description
The 12V Stationary Battery TAB 5 OPZS 350 | 527Ah is a 12 V battery bank assembled from 6 TAB OPzS 2 V cells (model 5 OPZS 350) connected in series. Thanks to tubular positive plate technology, it offers high float stability, very low self-discharge, and an extended design life, making it ideal for solar systems, telecommunications, and industrial backup. This set is delivered with the necessary flexible connectors and hardware for interconnection, ensuring a quick and safe installation.
Main Features
- Bank capacity: C100 ≈ 527 Ah (C10 ≈ 350 Ah at 12 V).
- Composition: 6× TAB 5 OPZS 350 cells (2 V) with OPzS tubular plates.
- Design life: up to 20 years at 20 °C in float operation.
- Reduced maintenance: low water consumption and long refill intervals.
- Translucent SAN container with level markings and cap with ceramic filter.
- Includes connectors, screws, and protectors for inter-cell connections.
Advantages or Benefits
- Modular solution: the 2 V format allows capacity expansion in parallel with identical banks.
- Excellent performance in long discharges (C10–C120), typical of photovoltaic self-consumption.
- Optimized total cost of ownership due to its long life and spaced maintenance.
- Easy visual inspection of the electrolyte thanks to the transparent container.
- High reliability for critical loads and sensitive equipment due to its voltage stability.
Purpose or Applications
Recommended for off-grid or hybrid solar installations at 12/24/48 V (via series/parallel), telecom base stations, UPS systems with extended autonomy, industrial control and monitoring, emergency lighting, and railway or airport applications.
