Solar controller for PV applications SPB-LS

SPB-LS is a charge regulator for the charge of batteries from PV module; it has been specially designed for the use in off-grid PV lighting systems (PV street-lamp). The charge controller code SPB-LS is housed inside a metal box that is protected from water (IP66 degree); therefore it can be installed directly on the PV pole without having to add additional protections. The charge circuit from PV module has got an efficient algorithm for the search of the maximum power point (MPPT) that is capable of operating over an extended field of voltages. It is allowed a maximum voltage on the PV module up to 100V. The regulator can charge either 12V Pb batteries or 24V Pb batteries. On power ON, SPB-LS automatically recognizes if the battery is at 12V or 24V and it automatically adjusts the charge thresholds. The regulator automatically manages the power on and off of the lamp. At dusk (when the voltage of the PV module drops below the Vnight threshold) the charge controller switches on the lamp and keeps it on for a number of hours that can be set by the user (the default setting is 8 hours). You can also set some programs for lamps power on with working hours with reduced flux (dimmer). In this way you can check accurately the lamp consumption so to remain inside the dimensioning of the PV off-grid system.
