Sun Power VR M 2V. 2-620AH Hoppecke AGM

Gel-ESS Technology

The construction principle of the HOPPECKE sun | power VR M batteries is based on the use of grid plates and ESS technology. Due to the high energy density, HOPPECKE sun | power VR M batteries have a very small space requirement and thus allow maximum use of the space. 

The indicative energy storage at C100 charge rate is: 616 Ah x 48 V = 29,6 kWh 

For 24V system the energy storage reaches 14.kWh

Your benefits at a glance

  • Maintenance-free due to refilling of water through innovative Absorbent Glass Mat technology (AGM technology)
  • Optimized cycle stability due to optimized electrode design for efficiently charge current acceptance
  • Higher short-circuit safety even during the installation – based on HOPPECKE system connectors
  • Optimum operational safety – integrated backfire protection
  • High current capability
  • Durable and suitable for every day deep-cycles
