20A Solar Charge Controller with LCD Display

20A Solar Charge Controller with LCD Display

Protect your valuable solar installation and maximise battery service life with Powertech's photovoltaic charge controller.

Using Pulse Width Modulation (PWM) technology, the unit is microprocessor controlled to get the most out of your solar system.

An LCD display and 5 LED indicators display voltage, current, charge status and battery levels.

With 3 stage, bulk, absorption and float charging the unit will efficiently charge a huge selection of batteries, including wet or sealed lead acid, lead calcium, lead antimony, Ni-CD and NiFe batteries, from a wide range of solar panels.

User adjustable charging voltages allow for different sized batteries to be charged.

An equalisation mode for wet type lead acid batteries automatically cycles once a month for 2 hours.

Amp hour logging readouts in 3 sets, present day and previous two days.

There are 10 selectable on-off programs which can be set to automatically turn the unit on and off throughout the day and night.

Safety features include overcharge protection, back current blocking to panel, low voltage automatic disconnect and reconnect, reverse polarity protection and over temperature protection.
