Due to integrated fuse holders, fuse based overcurrent protection can be implemented directly within the inverter.


When ordering your inverters, you can choose whether the positive pole is populated with six 15 A / 1,000 V fuses (supplied by Littelfuse/SIBA/Bussmann) or with bolts. The fuse holders on the negative pole are normally equipped with bolts.


The types of fuse used have been specially developed to protect photovoltaic modules and operate up to 20 kA. Furthermore, the plug-in modules allow individual fuses to be quickly replaced in the event of a fault.


  • Nominal Voltage: 1000 VDC
