Solar Charge Controllers/Regulators

Sunray Solar stock both PWM and MPPT type charge controllers. PWM controllers are suitable for low power situations such as off grid installations less than 1Kw. They are less efficient than MPPT controllers and as a result are the base economy range. MPPT controllers constantly monitor the energy produced by the sun, and adjust the charging output accordingly to ensure high sun to electricity conversion efficiency. Some of the larger MPPT chargers have user programmable charging cycles, but all of our charge controllers have 3 stage intelligent charging for various types of battery.
