Solar Panels and Controllers

Models 6904I, 6912D-12 & 6912CR-12

  • Overview

    Solar Powered Systems

    The solar powered system enables the long-term use of 12V sealed lead acid batteries  in the field without the need for recharging from the mains. The entire system is designed to be maintenance free once installed.

    Solar powered system consists of Solar Panel (6904I range), Sealed Lead Acid Battery (6907B range) and Solar Controller (6912D range)
    This set may be used for externally powering all data loggers, Starflow and conductivity instruments.

    In an installation with a prolonged period (more than 10 consecutive days) without sunlight we recommend the using the Model 6904I-10 Solar Panel (10W) with two Model 6907B-14 Sealed Lead Acid Batteries (28Ah). This system will also operate a cellular phone site for up to 5 “sunless” days.

    Solar Panels – Model 6904I
    6904I-10 12V 10W MONO Pole Mounting Bracket Included
    6904I-20 12V 20W MONO Pole Mounting Bracket Included
    6904I-50 12V 50W MONO Pole Mounting Bracket Included

    Solar Power Controller – Model 6912D-12
    This unit is designed to regulate the charging of a 12 volt sealed lead acid battery via a solar panel.

    6912D-12 12V 10A Series Controller

    Solar Power & Relay Controller Dual Relay Output – Model 6912CR-12
    This unit regulates the charging of a 12 volt sealed lead acid battery via a solar panel and provides a supervised 12V modem power output. In addition to this, controller has two 2A relays with capacity to operate either solenoid or small pump. Any Unidata logger can interface with the controller allowing program control of the two relay outputs.
