Solar battery Hoppecke 105 Sun Power VR M 12V

Roun battery from the German manufacturer Hoppecke, which was developed specifically for use in solar island systems and offers extremely high cycling resistance - e.g. 3200 cycles at 40% discharge see the graph on this card or also in the attached sheet. The Sun Power VR M batteries are valve-controlled maintenance-free batteries with an electrolyte bonded in glass fleece (AGM). This technology makes the batteries completely maintenance-free for the entire lifetime of the battery.

The main advantages of the battery are:

developed specifically for solar island systems
high cycling resistance
high number of charge cycles, which is particularly important in solar applications
long lifetime
high performance
compatibility with existing technologies
