Low- maintenance, vented lead-acid battery (OPzS series)

sun | power V L

sun | power V L is a low- maintenance, vented lead-acid battery, which is perfectly preserved for cyclical use. The tubular plates are made with woven gauntlets, which contain a very high resin content and are used for a long, robust period. The active material in the positive electrode must hold high physical stress in the area of ​​renewables, because the discharges are usually very long and the discharge current is very low; The consequence after discharges is that the active material has to be kept stable in order not to erode. HOPPECKE is the experienced partner who will guide you in the design and advise you, especially on the charging algorithms of the charger which is used. The product robustness has been provided with standardized evidence (IEC 61427 type test). The longer water filling interval and increasing of the service life can be achieved by using HOPPECKE sun | air.
