The new transformerless SOLIVIA 15 TL and 20 TL have an impressively large input voltage range from 200 to 1000 V and an operating temperature range of -20 to +60° C. This enables the SOLIVIA 15 TL and 20 TL to reach the extremely high peak efficiency of up to 98 percent, even on hot days. Two integrated MPP trackers enable maximum flexibility in system configurations. The transformerless SOLIVIA 15 TL and 20 TL are also equipped with an integrated DC-load switch so that the devices can be easily disconnected from the electrical grid for maintenance. Dustproof and shockproof, the inverter casing protects sensitive components from all kinds of weather conditions. And the included mounting hardware allows these SOLIVIA inverters to be quickly and securely mounted on the wall for easy installation.
