The KT 10 Amp Solar Charge Regulator is designed to regulate the amount of charge coming from the panel that flows into the deep cycle battery in order to avoid batteries being overcharged. 

KT’s range of solar regulators are PWM (Pulse Width Modulation) which are the most commonly used as they do not use moving parts like an MPPT controller, making them suitable for use on panels that are constantly being transported or moved eg; on the roof of a caravan, fitted to the back of a transportable, folding solar panel etc. PWM solar chargers use technology similar to other modern high quality battery chargers. When a battery voltage reaches the regulation set-point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery, yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.
