Specifications
Product Description
The 48V Stationary Battery TAB 7 OPZS 490 | 737Ah is configured with 24 TAB 7 OPZS 490 cells of 2 V connected in series, achieving a robust 48 V battery bank for stationary use. The OPzS tubular positive plate technology ensures great stability in float operation, low self-discharge, and a long design life. It is a professional solution for off-grid solar installations, industrial UPS, and telecommunications. The supply includes flexible connectors and hardware to complete the interconnection with minimal contact resistance.
Main Features
- Bank capacity: C100 ≈ 737 Ah (C10 ≈ 490 Ah at 48 V).
- Composition: 24× 2 V TAB 7 OPZS 490 cells with OPzS tubular plate.
- Design life: ≈20 years (20 °C, float); self-discharge ≈2–3 %/month.
- Translucent SAN containers with level markings; caps 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 of PV self-consumption.
- Spaced maintenance and low water consumption: lower total cost of ownership.
- Quick visual inspection of the electrolyte for preventive maintenance.
- 2 V modular format that facilitates expansions and cell-by-cell replacements.
- 24/7 voltage stability for sensitive loads and electronic equipment.
Purpose or Applications
Designed for 48 V banks in off-grid or hybrid photovoltaic systems, long autonomy UPS, telecommunications base stations, emergency lighting, and industrial control and monitoring systems.
