20A PWM Solar Charge Controller for 12V/24V Batteries



PowerECO fulfillment center will remain open to ensure that you are equipped with the reliable energy solution. Please note that due to an increase in order volume, there may be a slight delay. Thank you!

  • Automatically recognized 12V / 24V Batteries, charging for Flooded (FLD) Sealed (SLD) and GEL Lead-acid Batteries as well as Lithuium (Li) Batteries; charging from no more than 300W solar panels for 12V batteries, no more than 600W for 24V batteries. Matching Powereco solar panel ASIN: B06XPZD6G5
  • Safe and efficient with protections: the solar charge controller provides overcharge, over-discharge, overload protection, short-circuit and reverse-connection protection. An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, it effectively prevent battery from non-equalization and sulfuration, thus extending the battery's service life (except GEL and lithium batteries). TVS Lighting protection is adopted.
  • User-friendly operation: a dot matrix graphic LCD screen and a human-machine interface with 2 keys ensures convenient and intuitive operations, and the RJ12 data port (output of TTL232 level or Bluetooth signals), with the data adopting the standard Modbus protocol can be used together with our upper computer monitoring software or mobile phone APP.
  • Other features: With temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries). USB output insert. Industrial grade design ensures function well in various tough conditions.
  • 100% Satisfaction guarantee. USA based company support with technical team. 12 month warranty.
