Solar power technology – Solar charge controller

energy – almost at zero cost

VOTRONIC’s “AllSeason” solar controllers, featuring MPPT (Maximum Power Point Tracking) technology, are among the best in solar charging technology. An intelligent microprocessor continuously determines the solar module’s maximum power point—that is, the point with the highest power output. The excess voltage is automatically converted into additional charging current for the battery.

Advantages:

• More charging current with the same module surface
• Shorter charging time
• Higher energy yield in every season—but especially in cooler temperatures, during the transitional seasons, or with modules that have a higher number of solar cells.

Compared to conventional PWM controllers, VOTRONIC MPPT controllers have been proven to deliver more charging current—especially with modern solar modules featuring high open-circuit voltage. The high-frequency switching technology, combined with highly efficient components, ensures minimal losses and maximum efficiency.

The devices charge fully automatically and precisely adjust the charging current and voltage to the specific battery type. An intelligent control system protects against overcharging and automatically detects when recharging is needed, even while the battery is in use.

Two charging outputs:

• Main output: For the onboard battery—whether lead-acid, gel, AGM, or
  modern LiFePO4 batteries
• Second output: For maintaining the charge of the starter battery

Special Feature:
A special charging program for heated LiFePO4 batteries enables efficient charging in cold conditions, even without an additional temperature sensor—a real advantage over conventional solar charge controllers. In short: VOTRONIC “AllSeason” MPPT solar charge controllers get the most out of your solar system
—safely, efficiently, and fully automatically.
