How Do Solar Boost ControllersIncrease Charge Current?Solar Boost controllers increase charge current by operatingthe PV module in a manner that allows the module to produceall the power it is capable of. A conventional charge controllersimply connects the module to the battery when the battery isdischarged. When the 75W module in this example isconnected directly to a battery charging at 12 volts its powerproduction is artificially limited to about 53 watts. This wastesa whopping 22 watts or nearly 30% of the available power!Patented MPPT technology used in Solar Boost controllersoperates in a very different fashion. The Solar Boost controllercontinually calculates the module’s maximum power voltage,in this case 17 volts. It then operates the module at itsmaximum power voltage to extract maximum power. Thehigher power extracted from the module is then provided tothe battery in the form of increased charge current. Inconditions where extra PV power is not available, Solar Boostcontrollers will operate as a conventional controller with verylow voltage drop.Typical 75W PV Module Performance 25ºC Cell • 1000W/m 2PV AMPS543210Conventional controllercharging at 12V onlyextracts about 53W.0Solar Boost MPPTcontroller operates module atits maximum power voltageextracting full 75W.5 10 15 20 25PV VOLTS100806040200The actual charge current increase you will see variesprimarily with module temperature and battery voltage. Incomfortable temperatures, current increase typically variesbetween 10 to 25%, with 30% or more easily achieved with adischarged battery and cooler temperatures. What you canbe sure of is that Solar Boost charge controllers will deliverthe highest charge current possible for a given set ofoperating conditions.PV WATTSSPECIFICATIONS Solar Boost 2000EOutput Current RatingNominal System VoltagePV Open Circuit VoltageStandby Power ConsumptionCharge On Power ConsumptionCharge AlgorithmCharge Voltage Setpoint RangeEqualization VoltageTemperature CompensationPower Conversion EfficiencyPanel DimensionsConstructionFront Panel DisplaysDigital Display Range/AccuracySpecified Temperature Range25 Amp Maximum12 VDC30 VDC Maximum17mA Typical70mA TypicalFully automatic two stage charge, Bulk & Constant Voltage.
