Lento’s advanced line of affordable solar chargers are compact, ruggedized for operation in extreme weather conditions and are designed for durability. This line of solar chargers are designed to work in standalone solar power systems where they form an essential link between the SPV modules and the battery. Our solar chargers play a crucial role in maintaining battery health, better efficiency and improved performance.
MOSFET based solar charger incorporates circuitry that senses battery voltage. If voltage falls below a certain value the MOSFET switches on through the PWM controller that delivers pulsed power. As battery begins to charge up the power to it progressively reduces and when the battery is fully charged the circuit switches off delivery of power to the battery keeping it in full stand by condition. This circuitry also prevents over charge of battery that can lead to loss of electrolyte. It works unattended and is simply to operate as well as maintain, with the least part count.
Additional circuitry can be incorporated for automatic switch on of power to lights, such as in streetlights. Circuitry is also incorporated to detect battery temperature and to provide deep discharge as well as overload and reverse polarity protection both at input and output of the charger.
