The OPzS batteries from Hoppecke are filled with liquid electrolytes (diluted sulphuric acid). Each vented tubular battery cell has a 2V output. The OPzS batteries are ideal for deep discharge cycles which is the case in off-grid photovoltaic applications. 

Voltacon is an authorised distributor of Hoppecke with 15 years of experience in the field of Renewable Energy. We selected the most appropriate batteries for uninterruptible power even in extreme conditions and highly demanding solar applications. 

SCOPE OF SUPPLY

We will deliver to you fully charged and filled with liquids 2V battery blocs with insulated copper bus bars. Using the interlink accessories the batteries can be configured in 12V, 24V and 48V DC systems.

STAY CHARGED LONGER

The life expectancy of our batteries is one of the longest in the global market. You can feed power to your off-grid solar system up to 20 years. That means over 3000 cycles with 50% depth of discharge (DOD).

THE MOST EFFICIENT LEAD ACID BATTERY

The voltage per cell is 2V with an efficiency of 90-95% and operating temperature from -20 to +50 degrees Celsius, these batteries are suitable for any climate around the world, you will be powered non-stop in Antarctica, Africa or in the Mediterranean zone. 

WHY HOPPECKE BATTERIES ARE THE RIGHT CHOICE

• Up to 20% longer life span compared to conventional vented tubular batteries
• Optimised for the smallest to the largest off-grid solar system
• Large capacities up to 3000Ah without paralleling 
• Visible control of electrolyte level thanks to clear transparent housing

Using the optional AquaGen recombination caps they have extremely long intervals between topping up with water.

The Hoppecke OPZs batteries are manufactured to DIN standards (IEC-61427) for the support of photovoltaic systems.
