Product Description :
Tru Power Charge Controller 12V 4A: A good solid reliable Charge Controller is a key component of any solar battery charging system. Solar PV charge controllers allow you to use the uncertain voltage of a solar panel and condition it to safely charge lead-acid batteries. The CT-XR4A is designed to be used in conjunction with our ThinFilm solar panel series or any other commercial-grade solar panels.

These controllers enable you to utilize the power of the sun without overcharging your batteries and causing potential electrical damage to the devices you are powering. They feature built-in charging circuitry which prevents battery overcharging and internal crystallization in lead-acid batteries.

This simple do it yourself solar charge controller is suitable for all 12v solar panels up to 4A DC and can be installed in your system in minutes.


  • Overcharge protection circuit
  • LED charging indicators
  • Copper wire terminals for quick connect/disconnect
  • Durable design
  • Designed for 12v rated solar panels (up to 21 VOC)
  • 4A maximum input charging current
