Bateria solar AGM Offgridtec 260 Ah 20HR 12 V extremamente resistente a ciclos

The Offgridtec solar battery is a sealed AGM storage battery for use in solar and hybrid systems as well as other stationary 12 V energy systems. With a nominal capacity of 260 Ah (20HR), maintenance-free AGM technology and low self-discharge, it is suitable for both cyclic applications and standby operation in emergency power and UPS systems.

• AGM technology with a sealed, maintenance-free design.
• 260 Ah capacity (20HR) at 12 V system voltage.
• Particularly cycle-resistant for regular charging and discharging.
• Up to 500 cycles at 50% depth of discharge or up to 1,200 cycles at 30% depth of discharge.
• Low self-discharge of approx. 2–3% per month at 25 °C.
• Robust ABS housing with M8 screw terminals.
• Maintenance-free operation without refilling electrolyte.

The battery uses AGM technology (Absorbent Glass Mat). The electrolyte is bound in a glass fibre mat, so there is no free liquid electrolyte. This reduces maintenance and enables safe operation in stationary energy systems. The materials used – lead dioxide and lead plates, glass fibre separators and a resistant ABS housing – ensure a durable construction.

Typical areas of use

• Photovoltaic and solar island systems
• Hybrid energy systems
• Uninterruptible power supplies (UPS)
• Emergency power supplies
• Telecommunications systems
• Alarm and security systems
• DC power supplies
• Automated technical systems

Capacity

Depending on the discharge rate, the following capacities are available:

• 261.8 Ah (20HR)
• 250.0 Ah (10HR)
• 219.15 Ah (5HR)
• 135.51 Ah (1HR)

The internal resistance is ≤ 2.8 mΩ (at 25 °C, fully charged).

Charging

For cyclic operation, a charging voltage of 14.40 to 14.60 V at 25 °C is recommended. In standby operation, the recommended float voltage is between 13.50 and 13.80 V.

Scope of delivery: M8 connection screws.
