Extra Features

TSI Technology - The TSI Enhanced Power Conversion mode develops a high quality AC by drawing power simultaneously from the AC mains and DC sources and presents a regenerated AC for critical application. Since the system draws power from each source simultaneously, output power is guaranteed as long as one input source is available.
