The SPS Series Solar Regulation System is an advanced electronic control unit for solar power supplies in remote locations. It will prevent overcharging, reduce electrolite loss and stop over discharge. This will extend battery life and reduce maintenance.
State of the are technology has been combined with simple modular construction to create a system with better performance and more features than any other regulator in its class. All control levels are fully adjustable and can even be changed by remote control. They are flexible in use, easy to service and are powering telecommunications in some of the most remote parts of the world.
|The SPS Series use a standard control board which can be used with a variety of switch boards. The range of combinations available is set out below. All versions can be ordered without load control if required.||
The SPS series is designed to control the charging of batteries from photovoltaic panels and to protect the batteries from excessive discharge. It is designed for use in remote power supply systems for telecommunications or monitoring equipment.
Two stage boost/float regulation is used. The regulation voltages are easily adjustable via the keypad and display. Up to four stage bank switching can be used which allows taper charging in the boost mode and low speed switching regulation in the float mode. The regulator achieves very low levels of audio and radio frequency emissions and is well suited to use with telecommunication equipment in weak signal areas.
The load switch allows load disconnection when the battery voltage is too low or too high. The low and high disconnect voltages are adjustable.
The Control Computer
A microcontroller with hardware watchdog protection is used with a 16 x 2 line alphanumeric LCD and sealed keypad. Set up data is stored in non-volatile EEPROM. Battery & Load voltage, Charge & Load current and array data can be displayed
The microcontroller collects performance statistics. It logs daily charge and discharge amp hours and battery maximum and minimum voltages for 32 days.
Alarms and generator control are provided by voltage-free relay contacts. An external sensor for temperature compensation of the voltage settings can also be installed.
An RS232 serial port is provided which allows remote examination of the performance of the system and adjustment of the operating parameters.
Modular construction allows simple field repair. Two test programs are built in. The unit can be housed in a cabinet sealed to IP55 standard. Operating range is -15 to 60oC. The standard configuration is positive ground.
Circuit breakers are provided to protect the batteries against fault conditions. To guard against lightning, surge protection has been included.
