The CLASSIC OPZS SOLAR batteries have been well-proven for decades in medium and large photovoltaic systems. Based on DIN standard sizes and tubular flooded plate technology. The Classic OPzS Solar batteries provide the highest level of reliability and cycle life with low maintenance, thanks to a large electrolyte reserve. Due to their robustness, long life and high operational safety they are ideally suitable for use in solar and wind systems, telecommunications and other safety power supplies (up to 3000 cycles at 60% depth of discharge).
