Which Type of Solar Controller

Solar Charge Controllers are either Pulse Width Modulation (PWM) or PWM with Maximum Power Point Tracking controller function to provide up to 30% higher battery charging efficiency. Although MPPT controllers are more expensive a high quality branded model provides superior charging by using a mathematical formula (Algorithm) to increase charging power.

We have MPPT controllers from EP Solar which are very good quality having been used at Renytek for 12V battery charging.
