SR-HP4840 – PWM SOLAR CHARGE CONTROLLER (48V, 40A)

Product Enquiry

FEATURES

  • Except HP4830 /40, 12V/ 24 V system voltages are automatically recognized.
  • Charging program options for sealed, GEL and flooded lead-acid batteries and lithium batteries are available.
  • An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery’s service life (with the exception of GEL and lithium batteries).
  • With temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries).
  • A wide range of load working modes facilitate the product’s application to different types of street lights and monitoring devices.
  • The product provides overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.
  • By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
  • A range of parameter settings and power-down saving functions are available ,thus requiring no repeated setting.
  • The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.
  • The user-friendly design of browser and animation interfaces ensures convenient and intuitive operations.
  • (An optional communication function) provides a RJ12 data port (output of TTL /MAX232 /bluetooth signals), with the data adopting the standardModbus protocol, and can be used together with our upper computer monitoring software.
  • Boasting an industrial grade design, the product can function well in various tough conditions.
  • TVS lighting protection is adopted.
