SR Electronics manufacturing a wide range of solar PV charge controllers for solar home lighting systems, street lighting systems and for various solar PV applications. Charge controllers, which protects battery from over charging and/or excessive discharge are the essential components of Solar PV systems. SR Electronics introduces professional Solar Charge Controllers using the most innovative and state of the art Charge controllers, which protects battery from over charging and/or excessive discharge. The 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.
