Set consisting of 12 MVSV 2V 420Ah gel cells, supplied in 1 transport box. Allows 12V or 24V battery banks to be configured by means of series and parallel connections.
This set brings together 12 gel cells from the MVSV range, each with a nominal voltage of 2V and a commercial capacity of 420Ah. It is intended for high-capacity stationary systems that require reliable energy storage, continuous operation and flexibility to adapt the battery bank to the characteristics of the installation.
The standard configuration connects the 12 cells in series to obtain a 24V, 416Ah nominal bank. They can also be arranged as two strings of 6 cells connected in parallel to configure a 12V, 832Ah nominal bank. In series the voltages add up and the capacity remains the same; in parallel the voltage remains the same and the capacities add up.
To ensure balanced operation, all connected cells and strings must be of the same range, model, capacity and state of charge. New cells must not be combined with used units.
Valve-regulated lead-acid technology keeps the electrolyte immobilised in gel and does not require topping up with water. The cells can be installed in a vertical or horizontal position, always with the same orientation within the bank. In horizontal installations, each unit must rest individually on a suitable rack along its entire surface.
The 12 cells are supplied in 1 transport box.
