Long life – High tolerance to cycling
OPzS batteries provided by Conergy are low maintenance stationary batteries and are especially designed for capacitive discharges with autonomy from some minutes up to many hours. They are optimised for solar applications and have proven in many photovoltaic installations, that they are durable even at deep discharges (C-120, C-200), which can occur in stand-alone PV installations.
Design life of 15 years at 20 °C
In standby parallel operation, proven in the field. Long working life even with CYCLIC discharges IEC 896-1 cycles >1200 (ref. to 80% of C-10h)
Water refilling interval approximately tree years
In standby parallel operation due to plate alloys, therefore the need for maintenance is minimised
High operational efficiency and reliability
Very high mechanical and corrosion-resistant construction due to Tubular plate technology
Deep-discharge recovery of tubular design
Due to tubular plates, the cells can be fully recharged even after a not avoided deep discharge
Cost-effective battery solution
For all applications where high autonomy, extended working life, low maintenance and high operational safety are specified |
