Description
The separators are highly porous, and the gel holds the electrolyte between the plates, so the acid does not stratify even at partial charges, which are usual for solar systems. The tubular positive plate holds the active material well during deep discharges. The cells are sealed and have valves, so they can be installed in technical rooms without a separate battery room, although ventilation is still calculated. Compliance with IEC 61427 confirms suitability for photovoltaic systems, while DIN 40742 and IEC 60896 apply to stationary gel batteries. The number of cells connected in series determines the bank voltage for the input of a hybrid inverter.
How to choose
The first question is the operating mode. SMG/S are designed for frequent cycles, whereas ordinary SMG works on float. The cell capacity is chosen for the daily consumption and the permissible depth of discharge. If there is a ventilated room and staff for topping up, flooded LM/S per IEC 61427 are an alternative.

FAQ
How long do SMG/S gel cells last?
The service life is 12 years and more per the Eurobat Long Life classification. The real life in a solar power plant depends on the depth of discharge and the temperature.
What is the voltage of one SMG/S cell?
The series is made as 2 V cells. A battery of the required voltage is assembled by connecting cells in series.
Do OPzV gel cells need maintenance?
Water topping up is not needed, as the gas recombines inside the cell. The cell voltage, the tightness of connections and the room temperature are monitored.
How does SMG/S differ from SMG?
SMG/S has highly porous separators and is designed for frequent cycling per IEC 61427, while SMG is intended for float operation in telecom and power engineering.
Can SMG/S be used with a hybrid inverter?
Yes, a bank of 2 V cells is assembled for the voltage of the inverter battery input, and the charging parameters are set according to the manufacturer data for gel batteries.
