- The exact scored model CORE1 50-41 is not named on SMA India's current product list. India has no public per-model BIS register, so registration is not independently verified here. Absence from that catalogue is a listing fact, not a quality finding, and does not change the global score. That list names Sunny Tripower CORE2, Sunny Tripower 125 and Sunny Highpower PEAK3. The former CORE1 path now opens the German successor page and is not an Indian listing. Existing AU, US or DE warranty terms are not transferred.
