Generac PV Link is a non-isolated boost-type DC-DC optimizer. It raises the PV input voltage and feeds it onto REbus, Generac's regulated 380 VDC bus. It is rated for 2,500 W continuous, with a 420 VDC absolute maximum input, an 8 A continuous output current and a 99 percent peak efficiency. It uses power line communication on its DC output and includes ground fault protection, arc fault protection and rapid shutdown. Firmware updates arrive over the air. Connect it only to REbus-compatible equipment such as the PWRcell Inverter, never to a conventional PV inverter. Use Staubli MC4 connectors only. Never wire PV Links in series. You can parallel at most three on one home run. Units leave the factory disabled. Enable each one from the inverter control panel. If a PV Link shows offline, check its DC disconnect, its PLM channel setting, the REbus wiring and the REbus fuses. It is certified to UL 1741, UL 1699B and CSA C22.2 No. 107.1.
