TheAmptSPTputstheMPPTlogicwhereitbelongs,oneachsolarmodule,andallowseachmoduletoproduceits
maximum power. Then each SPT device combines to provide the bulk inverter with its highest efficiency input
power.Theresult:thehighestenergyfromeachmodule,
operatingwiththehighestefficiencyofthebulkinverter.
INSIMPLETERMS ,THESPT:
 ReceivesthepowerfromthemoduleatitsMaximumPowerPointTracking(MPPT)regardlessof
normalorproblematicoperatingconditions
 DeliversmoduleMPPTpowerintoanyimpedancedeterminedbytheremainderofthestringandthe
inverter
 Solvestheproblemofhavingpanels(currentsources)inseriesbeing
limitedbytheweakestpanelin
thestring‐improvesstringsightingoptions
 Ensureseverypanelproduceswhateveritcanregardlessoftheremainderofthesystem
 Allowstheinvertertooperateatitshighestefficiencypoint
 Provideswirelesscommunicationoneachmodule,reportingmorethanjustpanel
voltage,current
andtemperature.Additionalinformationisresidentsuchasmoduleserialnumberand

 Wirelesscommunicationalsoprovidesdiagnosticinformationformaintenance,andthroughradio
