Shading Resistant Smart Modules with Hot-Spot free technology 

 Power Range: 5W-650W
 Available in mono and polycrystalline

    -    Supreme design and quality;

    -    Individual bypass diode for each cell. With Hot-Spot Free technology  protects each cell by an individual bypass diode;W

    -    When the current of a single cell does not match the current of the whole string, that cell has a reverse voltage, so when measured more than 0.6V, it will automatically activate the bypass diode. As a result, the rest of the cells will not be affected by the disruption;

   -      Increased performance ratio up to 30% ;

   -     We provide all International standards' certificates, 30 years performance guarantee and 12 years product warranty;
