The IPG Effi­ci­en­cy Kit

The IPG Effi­ci­en­cy Kit is the fully com­pa­ti­ble retrofit for central inver­ters of the Conergy IPG K series. In contrast to former com­pon­ents it operates com­ple­te­ly digital and thereby offers opti­mi­zed MPP-Tracking exact to the second. The IPG Effi­ci­en­cy Kit has been imple­men­ted over 50 times now and unlocks a yield increase up to 4 % over the year.

Core features of the IPF Effi­ci­en­cy Kit

  • Opti­mi­sed yield through MPP-tracking exact to the second
  • Increa­sed sta­bi­li­ty of the ope­ra­ting beha­viour and mini­mi­zed fault rates
  • Lower service efforts due to maintenance-free and low-maintenance com­pon­ents
  • Lower power con­sump­ti­on
  • Pos­si­bi­li­ty to perform active power manage­ment
  • Fast instal­la­ti­on by expe­ri­en­ced green­tech tech­ni­ci­ans

Further Details

Since 2005 about 3.500 inver­ters of the IPG K-series have been produced under the brands Conergy, Voltwerk and Sun­Tech­nics. These inver­ters rep­re­sent signi­fi­cant opti­mi­za­ti­on poten­ti­al through exchange of certain key com­pon­ents. The core part is the newly deve­lo­ped control unit for the inverter, which utilises all latest methods and algo­rithms in order to manage all com­pon­ents of the inverter in the most effi­ci­ent way. This includes a second by second MPP tracking, which enables the inverter to react imme­dia­te­ly towards changing irra­dia­ti­on con­di­ti­ons. With this impro­ve­ment we saw an addi­tio­nal yield of at least 3%. In the cause of repla­cing the analogue tech­no­lo­gy and the imple­men­ta­ti­on of the digital control unit, further com­pon­ents will be replaced, which increase the sta­bi­li­ty of the and reduce the error rate of the inverter. By the imple­men­ta­ti­on of low-maintenance com­pon­ents, the efforts for main­tai­ning the inver­ters will be reduced. The lower heat genera­ti­on has a positive impact on the effi­ci­en­cy and the reduced power con­sump­ti­on adds addi­tio­nal margin to your project.

Smart­Con­nect Retrofit

The reliable DC Combiner Box for Conergy plants: Defects and down­ti­mes of dis­tri­bu­ti­on boards can cumulate to high yield losses over time. The relay circuit of the Smart­Con­nect V1 and V2 was subject to frequent false shut­downs during changing weather con­di­ti­ons. The Smart­Con­nect Retrofit is an adequate and reliable repla­ce­ment for the Smart­Con­nect V1 and V2.

Major features of the Smart­Con­nect Retrofit

  • No housing repla­ce­ment required
  • Repla­ce­ment can be applied without struc­tu­ral alte­ra­ti­ons
  • Tried and tested melting fuses instead of elec­tro­nic circuits
  • Quick response times
  • Increa­sed avai­la­bi­li­ty and yield
  • Reduced O&M costs
  • Pos­si­bi­li­ty of string moni­to­ring: optional Add-On SCP 08SM

Data Com­mu­ni­ca­ti­on

Data com­mu­ni­ca­ti­on is the key for any moni­to­ring and remote analysis activity around your PV-plant. For a reliable com­mu­ni­ca­ti­on with all relevant com­pon­ents your plant needs a sound con­fi­gu­ra­ti­on of the com­mu­ni­ca­ti­on system. green­tech gained a profound exper­ti­se in desi­gning as well as opti­mi­zing com­mu­ni­ca­ti­on systems for PV plants – both software and hardware.
