  • Charge Controllers 



     Charge Controllers:-

    A charge controller, or battery charge controller limits the rate at which electric current is added to or drawn from electric batteries. Charge Controllers are used in Off-Grid Installations and they support function like: prevent overcharging, protect against overvoltage, prevent completely draining ("deep discharging") of a battery, perform controlled discharges, maintain the battery state of charge.

     MPPT Charge Controllers:-

    MPPT Charge Controller is a maximum power point tracker, a DC to DC Converter which takes the DC input from the solar panels and changes it to high AC frequency. That one in turn it is converted back to a different DC current to match with the batteries bank requirements. MPPT Charge Controller operates in the range of 20 to 80 KHz. The MPPT charge controller compares the output of the solar panels with that of the battery bank voltage, then determines the power the panels need to produce to charge the batteries.

     PWM Charge Controllers:-

    PWM is an acronym for Pulse Width Modulation. When the battery is recharged to a regulated voltage, the controller will begin limiting the amount of current into the battery in such the regulated voltage is maintained but not surpassed. The method of current regulation, referred to as PWM, pulses current into the battery with pulses of a varying length. Longer pulses allow a greater percentage of the current to flow into the battery, shorter pulses restrict current to a lower percentage.

     Lighting Controllers:-

    Fully waterproof PV Charge and Lighting Controllers used for area lighting, roadside signs, and warning signs, can be used with 12- or 24-volt systems, 15-amp and 40-amp versions are also available. Controllers have a motion sensor to activate the light or load when motion is sensed. They have temperature compensation and can be used with sealed or flooded batteries. Pulse action reduces sulphating.

     Generator Start Controllers:-

    Generator Start Controller allows your conventional auxiliary generator to automatically start based on low battery voltage and/or high temperature. A generator-starting controller receives start commands from the 12-volt output of an inverter auxiliary relay, a user-supplied switch, an auxiliary relay in an inverter, a voltage controlled relay, a timer or any user-supplied contact closure system.

     Relay Controllers as Logic Module Controllers:-

    The Relays are Logic Modules which provide control functions such as high/low voltage alarm, load control and generator start for 12-, 24- or 48-volt battery systems. It controls up to four independent relay driver outputs by reading digital data inputs or by reading battery voltage. The outputs can be used to operate any of the relays systems presented on this page or any other mechanical or solid state relay with a coil voltage that is the same as the battery voltage used to power the relay driver.
