Solar PWM Charger (P-0275) (MFN 4701)

Abstract

The technology for solar battery charge controllers has undergone great advancements in the past few seasons. The most emerging new technology isPWM algorithmic charging technique, which gained popularity increasingly.Charging of battery with solar panels is an exceptional and arduous challenge now a day. In the old days, simple on‐off switches were used manually to limiter the battery from overvoltageand overheating, when the solar panel produced excess energy in that time. However, as this energy system advanced it became clearedthat how these simple switching devices interfered in the charging process. The history of on offswitches has been early battery failures before the full charging, increasing inauto load disconnection, and growing use dissatisfaction. Pulse Width Modulation has recently prolonged technologyand it significantly advance in sun power battery charging system. This type of solar chargers usesthe PWMtechnique which has similarity with all other battery chargers. When a battery voltage will reachesits highest level then the regulation process will start. The PWM technique slowly reduces the voltage coming from the panel to avoid the heating and overcharging of the battery. The charging process continues to attain maximum amount of energy to the battery in the short interval of time. The result conducted is the full charging with effectiveness, rapidness recharging, and a full limit Dry cell life.
