SOLAR CHARGE CONTROLLERS regulate the amount of charging and discharging of the battery.
They prevent and protect the battery from over charging and/or excessive discharge.
Our controllers are built with best materials which results in outstanding performance.
The life span of our solar charge controllers is also very long.
These utilize latest technology ensuring very less self-consumption power.
