Our CompanyThe know-how of Schams-Electronic Ltd. is •based on more than 15 years of experience in the development of MPP Solar Charge Con-trollers and is state-of-the-art.

Our controllers are used worldwide, even in •the Antarctic.

Development with modern simulation pro-•grammes.

MPP-Charge ControllerWould you like to guarantee your customers an op-timum of solar power, not only during sunshine, but also during periods of bad weather, in winter and in summer while the accu is not overloaded and the wiring does not require great skills? In this case, you willfindourcontrollersverysuitable.

The Maximum Power Point controller (MPP) ensures maximumefficiencyofthesolarmoduleatalltimes.This may increase the charging rate up to 50%.

MPP-Charge Controllers for Wind Power Stations

More than 100% increase of charge current with •MPP Controllers, through optimized dimensioning of the wind generator station.Optimal adaptation of battery and wind generator •at varying windspeeds.Complete solution with the combination of all neces-•sary system components, like low voltage disconnect, load resistor connection, 3 phase rectifyer.

Additional Features of the Charge Controller

With our integrated DC-Converter it is possible •to transform solar voltage from 150V and wind generator voltage from 170V to a selectable bat-tery system voltage level.Due to our master-slave technique we can cus-•tomize the chargers. We offer controllers from 30W to 5kW.15 years of experience guarantee an optimal ben-•efitofyoursolar/windgenerator.

Benefits of our Charge Controller:Optimal adaptation of battery and solar module with •varying intensity of sunshineNodeficitwiththeinfluenceoftemperatureontheso-•lar cells, for example falling below the battery voltage when solar modules become too hot.Prevention of total discharge of the battery with •dynamic increase of the solar power at low battery voltage.Cabling with easy cable cross-sections, due to the pos-•sibility to choose higher solar voltage (up to 150V).Approximately 5 to 50% additional solar power •especially at times when it is most needed - during periods of bad weather and when the battery has been discharged.Easy handling and universal applications as for ex-•ample total discharge protection and dimmer as well as morning and evening timer for solar lighting all in one device.
