Charge Controllers SP40 MPPT 12V/24V/48V

PURPOSE:
SP40MPPT charge controller for battery charge from solar panels. In operation, the controller selects a mode of operation of solar panels, wherein the panels shown on the maximum possible at a given illumination power. The controller also provides an optimum battery charge

SPECIFICATIONS:
1) Properties device
- selection of the maximum power from the solar panels;
- the charging current - 40 k.
- input voltage from the solar panels - up to 145 V;
- batteries: lead-acid, alkaline (nickel-cadmium or nickel-metal hydride);
- three-stage charge battery temperature compensated charging voltage ;
- USB interface, RS-485 (Modbus protocol);
- the ability to update the internal software via USB, RS-485;
- a graphical display and keyboard allow you to configure the device easily and monitor his work;
- display of the system parameters, display of energy production graphs, calculation of energy generated by solar panels;
- indication of the total efficiency of the solar panels per day;
- preservation in non-volatile memory and resource data Zh ala events;
- possibility to use the device cooling fan, when operating at high ambient temperatures;
- relay for outputting a signal - feature battery charge
