LM Solar OPzS

Applications and Key Benefits

   - Solar 2V cells, up to 5.000 Ah real capacity at C120 1,85 VPC

   - Designed for regular and long deep discharge

Ideal for:

          • Renewable energy islands (Solar / Wind)

          • Off-grid applications: BTS, mobile phone stations, signaling, lighting,
             drinking water supply systems and other

          • High capacity applications in areas with unstable grid and unreliable
             power supply

   - Excellent cycling also in state of partial discharge

   - > 1.500 cycles at 20°C / 60% DoD

     > 5.000 cycles at 20°C / 20% DoD

   - OPzS technology, with tubular positive plates and free liquid electrolyte

   - Allows use with electrolyte recirculation

   - Dimensions according to DIN 40736 OPzS cells

   - Suitable for use at elevated temperature

   - Optimized for deep discharge recovery DIN 43539T5

   - 20 years design life under fl oat condition

   - Also available in dry charged version

Technical Features

   - Tubular positive plates with special low antimony lead alloy reduces loss of water
     (3-year topping-up intervals on fl oat condition)

   - Electrolyte: high purity sulphuric acid solution with 1,24 specific gravity at 20°C

   - Additional electrolyte to reduce topping-up

   - Pasted negative grid plates designed to have service lives consistent with
     the positive plates

   - Separators with extremely high porosity and low internal resistance

   - Container in acid resistant SAN, designed for unsurpassed mechanical strength

   - Lid in standard ABS

   - Threaded female M10 terminal posts guarantee highest conductivity,
     maximum torque retention and easy installation

   - High integrity post seal design to prevent electrolyte leakage and terminal corrosion

   - Ceramic plugs filter electrolyte from escaping gasses

   - Flame arrestors prevent sparks or flames from entering the battery

   - < 3% self-discharge per month at 20°C allows 6 months shelf life

   - Installation in vertical position

   - Flexible, fully insulated cable connectors with insulated screw with probe hole
     on the top for electrical measurement
