The S3 is a 12VDC integrated storage system, with built in charge electronics and control panel. The S3 has become the standard in countries where sales of solar systems is taking place on commercial basis with consumer finance, and thus there where end-users decide what products to buy. The long reliability-track-record of the product since introduction in 1993 and the attractive price makes the S3 your best choice.
The figure behind the code S3 (for example S3.600) represents the maximum Watt-hour capacity of the storage system. In case of a PV Solar power system for daily use we recommend to use a solar panel that provides maximum about 1/3rd of the capacity of the storage system.For an S3.600 this means that you should connect a solar panel that provides 200 Watt-hours per day.
