Star Energy Systems offers PWM[Pulse Width Modulation] Charging Type Solar Charge Controller. Star Energy Systems is an ISO9001:2000 certified company. It also offers solar space heating, solar refrigerator, solar power generator, solar spv dusk to dawn, solar army search light, solar fencing PWM[Pulse Width Modulation] Charging Type Solar Charge Controller uses PWM charging Technology, so that as the battery reaches full charge, the PWM pulses slower, gradually tapering off the charge. Pulsing is good for the batteries since it gently mixes the electrolyte, preventing stratification and sulphation. Low voltage disconnect protects the batteries from severe discharge by shutting off loads before the battery voltage drops to damaging levels .The PWM [Pulse Width Modulation] Charging Type Solar Charge Controller has temperature compensation adjusts the set point voltages according to the ambient temperature.
