About this product
The 1500V version, for the higher string voltages used on larger commercial and utility-scale arrays. Three modules covering DC+, PE and DC−, so the array is protected both between conductors and to earth.
The rated Uc of 1800V DC gives real headroom above the 1500V nominal. That margin matters more than it looks: a cold, bright morning pushes array open-circuit voltage well above its nameplate figure, and an arrester sized with no headroom will age prematurely.
