4th Generation JB electronics

The fourth generation of the system has been enhanced with electronics for junction box integration. With the new active bypass feature in the Optistring system losses are reduced from 5W of commonly used diodes down to below 0.3W at full PV module current, cialis further pushing the limits when it comes to efficiency. The major[…]

4th Generation

  The weighted cycle average efficiency for 4th generation is 99% in both the European and the Californian standard, sick including all electronics. The mass of the module electronics is slightly above 100gr per module and the full 4.6kW central unit weights in at incredible 3.6kg. A full 4.6kW system mass is in total 5.5kg including module[…]
