RES OPzS flooded batteries for renewables 89–4923 Ah
Country: Greece · Model: RES OPzS
RES OPzS flooded batteries of 89 to 4923 Ah, which withstand 2800 cycles at 50% DoD, are intended for off-grid and hybrid solar power plants. They work as a lead-acid system for storing energy from renewable sources where the battery is discharged and charged every day.

Description
The design is vented, the electrolyte is liquid and the gases are released through the vent plugs, so the battery is placed in a ventilated room and distilled water is added periodically. Tubular plates tolerate deep cycles better than flat ones, and they give the declared life at a temperature of 20 °C. The operating temperature lies between –20 and +55 °C, but in the cold the available capacity falls, and in the heat the life is shortened. The range consists of 2 V cells and 6 and 12 V monoblocs. 12 V monoblocs are convenient for building a small battery for a private plant, and large 2 V cells suit hybrid systems at commercial and remote sites. The liquid electrolyte makes it possible to check the acid density and to restore the battery with an equalising charge after deep discharges.
How to choose
Capacity is calculated from the daily consumption and the permissible depth of discharge, because at 50% DoD the battery delivers its full declared life. The system voltage is built by connecting 2 V cells or 6 and 12 V monoblocs in series for the input of a hybrid inverter. If the battery mostly stays in standby rather than being cycled, the gel OPzV of 54–3718 Ah with a service life of up to 20 years is better suited. For 12 V mobile systems with deeper discharges there are the TRIFORCE Lithium 12V LiFePO4 monoblocs with a life of up to 3000 cycles at 80% DoD.

FAQ
How many cycles does the RES OPzS battery withstand?
The declared cycle life is 2800 cycles at a depth of discharge of 50% and a temperature of 20 °C. Deeper discharges and higher temperature reduce this figure.
Can the RES OPzS be installed in an unheated room?
The operating range is from –20 to +55 °C, so the battery works without heating too. In winter a capacity reserve is allowed for, because in the cold the output is lower.
Does water have to be added to RES OPzS flooded batteries?
Yes, these are vented batteries with liquid electrolyte, so the level is checked and distilled water is added. The room must be ventilated, because hydrogen is released during charging.
Which voltages does the RES OPzS range of 89–4923 Ah have?
There are 2 V cells and 6 and 12 V monoblocs. The largest capacities are more convenient to build from 2 V cells, from which a battery for the voltage of a hybrid inverter is assembled.
