! How Does Solar Boost 3048Increase Charge Current?Solar Boost 3048 increases charge current byoperating the PV module in a manner that allows themodule to produce all the power it is capable of. Aconventional charge controller simply connects the moduleto the battery when the battery is discharged. When the75W module in this example is connected directly to abattery charging at 12 volts its power production isartificially limited to about 53 watts. This wastes awhopping 22 watts or nearly 30% of the available power!Typical 75W PV Module Performance25°C • 1000W/m 2Solar Boost 3048’s patented MPPT technologyoperates in a very different fashion. Solar Boost 3048calculates the module’s maximum power voltage, in thiscase 17 volts, and then operates the module at 17 volts toextract maximum power. The maximum power voltage iscontinually recalculated as operating conditions change.Module power, now 75 watts, feeds a high efficiencypower converter which reduces the 17 volt input to batteryvoltage at the output. The full 75 watts delivered at 12 voltswould produce 6.25 amps. An increase of 1.8 amps or40% is achieved by converting the 22 watts that wouldhave been wasted into useable charge current. This 12volt example assumes 100% efficiency to illustrate theprincipal of operation. Actual boost will be somewhat lessas some power is lost in wiring, fuses and in the SolarBoost 3048 controller.! How Much Increase Will You See?The actual charge current increase you will receivevaries with module temperature and battery voltage.Lower module temperature increases available power,while lower battery voltage increases current for a givenPV module power level. In comfortable temperaturescurrent increase typically varies between 10 - 25%, with30% or more easily achieved with a discharged batteryand cooler temperatures. What you can be sure of is thatSolar Boost 3048 will deliver the highest charge currentpossible for a given set of operating conditions. Inconditions where extra power is not available, SolarBoost 3048 will operate as a conventional series passcontroller with very low forward voltage drop.! Three Stage Charging Taken To TheNext Level…Solar Boost 3048 uses the familiar three stage, Bulk,Acceptance, Float charge algorithm. But, controllers thatdetermine full charge based on time or other factors notdirectly related to battery state of charge cannot realize allthe benefits three stage charging has to offer.Solar Boost 3048 uses battery charge current matchedto battery size in amp-hours to determine full charge. Thismethod charges the battery quickly and completely withoutundercharge, overcharge or excessive water loss. Whenbattery load is highly variable during charge, Solar Boost3048 can further optimize charge control by using anexternal current shunt measuring net battery current. Ifdesired, Solar Boost 3048 can also operate as a twostage charger.!

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.

Bare wire connections under the PBR charge regulator terminal blocks areacceptable. Mid- and High-Current PBR models accept up to two #10gauge bare wire inputs under each terminal clamp.2. When the battery reaches the pre-set maximum voltage level at a giventemperature, the PV module input will be shorted (“shunted”) to a valuenear zero volts. The battery voltage will gradually drop back to a lower voltage,at which point the regulator will release the PV input, and chargingwill resume.

The “Shunt“ voltage level is factory set.1. Ensure that the photovoltaic array is properly wired to match the nominaloperating voltage of the regulator and battery system (usually 12, 24 or 48Vdc).
