Description
The tubular positive plate keeps the active material inside a sleeve, so it sheds less during deep discharges. The series complies with DIN 40736 and DIN 40740, and the cycling characteristics are confirmed per IEC 61427, the standard for batteries of photovoltaic systems. The capacity of the smallest model LM/S 150 is given for a discharge lasting 120 hours, typical of off-grid solar plants with night consumption. Like all flooded batteries, the cells emit hydrogen during charging, so the cabinet or room must be ventilated. Connecting individual cells in series sets the bank voltage for the input of a hybrid inverter or charge controller.
How to choose
What decides here is the number of cycles, not the duration of float operation. For daily discharges in a solar power plant LM/S suit better than SGL/SGH, designed for 25 years of float, and than SD/SDH with 15 years of service for short powerful discharges. Choose the capacity for the daily consumption and the desired depth of discharge, starting from LM/S 150.

FAQ
What is the minimum capacity of LM/S cells?
The range starts with the model LM/S 150 with a capacity of 150 Ah at the C120 rate. Larger models have a higher capacity with the same technology.
Why is the capacity of OPzS for solar plants given at the C120 rate?
C120 means discharge over 120 hours, which is close to the real load of an off-grid solar plant. With a shorter discharge the available capacity will be lower.
Which standards do LM/S cells comply with?
They are made per DIN 40736 and DIN 40740 as OPzS, and also comply with IEC 61427 for batteries of photovoltaic systems.
Do cyclic LM/S cells need maintenance?
Yes, these are flooded vented OPzS cells; the electrolyte level must be monitored and water added. The topping up interval depends on the number of cycles and the temperature.
Can an LM/S battery be connected to a hybrid inverter?
Yes, a bank of cells from 150 Ah is assembled in series up to the voltage of the inverter battery input, and the charging parameters are set according to the manufacturer data for OPzS.
