20A Dual Battery Charge Controller - STCC20

This controller is designed to work on both 12v or 24v off-grid solar systems and has the additional functionality that it can charge two batteries simultaneously.

The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.

Features & Benefits

  • Reverse current protection.
  • Unique dual battery charging function.
  • Efficient Series PWM charging, increases battery lifetime and improves solar system performance.
  • 12/24V automatic recognition.
  • Overload protection.
  • Open circuit protection.
  • Lightning surge protection.
  • Deep discharge protection.
  • Charge current protection up to 20A.

All solar panels (except the 5W &10W) require a voltage regulator to ensure that the battery is not overcharged. We recommend the STCC20 20A Charge Controller for solar systems with a total wattage of 100 to 300W.
