Solar Charge Controller

• Advanced MCU control Pulse Width Modulated (PWM) technology, high efficiency operation.
• Suitable for Lithium, GEL, AGM, Conventional Lead-Acid (WET) and Calcium Batteries.
• Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the 
  charge voltage is unregulated. This can result in premature battery failure.
• The regulator prevents your battery from being under charged, in the solar energy field, battery 
  undercharge always occurs, especially on some conventional lead-acid or calcium batteries. The 
  unit provides an automatic equalization feature for deeply drained conventional lead-acid battery or 
  calcium battery, as well as provides a cycling automatic equalizing feature every 28 days.

The KT 20A, 12V Solar Charge Controller is designed to charge Deep Cycle Batteries. Suited to charge 

Lead Acid, Gel, AGM, Lithium & Calcium Battery types, this Solar Charge Controller prevents batteries 

from becoming overcharged. The unit provides an automatic equalisation feature for all battery 

chemistries. 

The PWM Solar Charge Controller features a digital LCD to directly display battery voltage, charging 

current, charging capacity, percentage present, battery type, fault codes. Coloured LED's indicate 

the operational status and each battery conditions. 

KT's range of solar regulators are PWM (Pulse Width Modulation) which are the most commonly 

used, 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.
