Solar Power Pack

Solar Power Pack 12V/2A

UTL Solar Power Pack is an integrated system consisting of Solar charge controller and Grid charger. For increasing the battery life, Solar Power Pack provides Smart Charging Technique (Bulk, Float and absorption). If battery voltage is charged to preset level, Solar Power Packgoes to cut-off mode and it disconnects the power from Solar or Mains.
Solar Power Pack is hybrid battery charger and DC power solution for DC equipment. It can provide power to battery and DC equipment using both solar as well as AC mains supply. Solar Power pack  uses microcontroller based MPPT algorithm to maximize energy from solar PV array. It has a number of output ports for fan, light, mobile charging etc. We provide A special feature of sleep mode so that system draw minimum current at no load condition.

    DC Output

    Solar Power Pack give DC Output for 12V DC fan, DC LED & low DC appliances. [Top]

    Sleep Mode & Wake Up

    We provide a special feature of sleep mode so that system draw minimum current at no load & no Input  condition. System wake up at presence of input or load. [Top]

    PV Charging Efficiency

    90% using microcontroller based MPPT technique. [Top]

    LED Indication

    LED indication for battery charging, battery low & overload. [Top]

    USB Interface

    USB use for data logging, USB parameter are charger On/Off, load on off, Battery % level. [Top]

    Preference to Solar over Grid

    Solar Power Pack gives first priority to Solar Power over Grid power during charging. It means that when Solar power is available the batteries will be charged through Solar Power for maximum then left power draw from mains. [Top]

    Electronic Protections

    There are number of protections that the power pack ensures. It stops reverse current flow from battery to solar array, it provides load short circuit protection, it provides Panel reverse protection and Overload protection also. [Top]

    Mobile Charging: A USB Port for Mobile Charging Protection

    1. Battery reverse protection
    2. Output short circuit protection
    3. Over load protection
    4. Solar reverse protection
    5. Surge voltage and protection
    6. Charging current limit from grid
    7. Deep discharge
    8. Protection against battery (night time leakage through PV)
