SMG Solar OPzV

Applications and Key Benefits

   - Solar 2V cells

   - up to 3.900 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

        • 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

Technical Features

   - Tubular positive plates, pressure cast from high tin / low calcium alloy

   - Electrolyte immobilized in gel structure

   - Highly porous gauntlets retain the active material

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

   - Separators with extremely high porosity and low internal resistance

   - Standard ABS plastics (Optional fl ame retardant plastics ABS IEC 707 FV0 and
     UL 94 V0 with LOI greater than 28%)

   - Container and lid designed for unsurpassed mechanical strength made of 
     thick walled plastics

   - 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

   - Flame arrestors prevent sparks or flames from entering the battery

   - Cells equipped with one-way safety valves to allow excess gas to escape
     when overcharging

   - < 2% self-discharge per month at 20°C allows 6 months shelf life

   - Installation in vertical or horizontal position

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