20A Solar Charge Controller with LCD Display

Powertech



Protect your valuable solar installation and maximise battery service life with our photovoltaic (PV) charge controller. Microprocessor controlled with LCD display, this charger efficiently charges a vast selection of batteries from a wide range of solar panels. It even features an equalisation mode for wet type lead acid batteries, automatically cycles once a month for 2 hours. See our website for full documentation.

Features

  • User adjustable charging voltages
  • Suits wet or sealed lead acid, lead calcium, lead antimony, Ni-CD, NiFe batteries
  • Microprocessor control PWM (Pulse Width Modulation) for optimum charging
  • 3-stage, Bulk, Absorption and Float charge with status on LCD display
  • Ampere Hour logging readouts in 3 sets, today and last 2 days
