Solar controller for PV applications SPC07IP

SPC07-P is a charge regulator for 12Vdc PV applications. It is able to manage the recharge of Pb batteries and two different DC loads of max 7A total current, with eleven different configurations. Light sensor detection is made by the module. The recharge algorithm is PWM - Mosfet with voltage compensated in temperature: through an external NTC sensor (optional) or through the sensor inside the circuit which supply also a protection against over-temperature. SPC07-P includes also a blocking diode to avoid the discharge of battery through the PV modules; at the same time a Low-Battery control save the battery from deep discharges caused by the load consumption. A bi-coloured LED shows eventual status of error (red colour) and presence of panel current (green colour), two yellow LEDS show the activation of each load. SPC07-P can simultaneously power two independent 12V DC loads with total current limited to max 7Amp, if only one load is used the maximum current of 7A can be supplied to this one. The circuit is inside a IP56 compact box which has already got chocks to have an easy connection to PV module and battery. The regulator is equipped with a connection board with cables up to 2,5mmq for battery and panel, while the connection of sensors can be made using cables of 1,5mmq max section.
