The solar charge controller with maximum input power of 30W for 6V systems and 60W for 12V systems. This PWM charge controller features multiple protection functions, including overload and short circuit protection. If the current exceeds 1.5 times the rated current, the solar power charge controller will shut down for 5 minutes and then automatically recover. If the current reaches 3 times the rated current, the short circuit protection will be triggered immediately. Additionally, the 5A controller provides overvoltage protection, undervoltage protection, and over-discharge protection to ensure battery safety under various operating conditions. Wide range of applications for small solar home systems, outdoor camping, RVs, boats, and remote monitoring systems. 

5A PWM solar charge controller feature


  • Ultra-low power consumption on standby
  • The charging principle adopts a three-stage charging algorithm, charging the battery once a week in a balanced manner, effectively preventing battery imbalance and sulphation phenomenon, and enhancing the service life of the battery.
  • The power MOSFET acts as an electronic switch without any mechanical switching and without any delay in protective action.
  • Charge/discharge green and red LED indication, battery level indication.
  • Discharge mode: light control + timing, pure light control, normally open mode (manually adjustable)
