Tubular Plate Batteries for Renewable Energy Storage. 24kWh, 2V Cells, 520Ah, Filled with Acid. Suitable for Off-Grid Photovoltaic Applications.

In this listing we offer a full battery bank with 24kWh total energy storage. The batteries are OPzS technology suitable for deep-cycle photovoltaic applications. 24 blocs are connected in series to form a 48V system. 

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 for up to 20 years. That means over 3000 cycles with 50% depth of discharge (DOD). The usable charge at C10 is 18kWh.

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. 

COMPREHENSIVE OFF-GRID ENERGY STORAGE

The battery bank is placed on a single pallet that contains

• 24 pieces of OPzS 520Ah, 2V per bloc
• 100A DC fuses with disconnector
• Copper busbars fully insulated for safe and quick installation
• Filled with de-ionized water and fully charged
• Battery cables 2.5 meters, for connection to the solar charger
• A hydrometer for measuring the state of charge of the battery cells, it measure the density of the electrolyte
