## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Working well using this as a controller providing back up to the solar panels.
  

*by A***. on Reviewed in the United Kingdom on 22 November 2018*

Instead of using a complicated system to charge the batteries when low light & problems I use a (Surom 24V 15A Dc Universal Regulated Switching Power Supply 360W for CCTV, Radio, Computer Project) to back up the solar system, just incase of real bad weather, works well. Added a bridge rectifier to isolate the components and prevent feedback. Once fully tested will update. still working ok
