Generac PWRcell 2 is a Generac inverter system family that pairs the PWRcell 2 Inverter with the PWRcell 2 Smart Disconnect Switch and batteries. The PWRcell 2 Inverter is rated for 11.5 kW of maximum continuous AC power, and its grid support settings use an apparent power rating of 11500 VA. Its CEC weighted efficiency is 98.0 percent, and its AC-to-DC-to-AC round-trip efficiency is 85 percent. Used with the Smart Disconnect Switch, the inverter is certified to IEEE 1547-2018 for Normal Performance Category B and Abnormal Performance Category III, and to UL 1741 SB. The SDS compliance table also lists SunSpec CSIP, NERC PRC-024-3, the New England bulk system default settings, and FCC Part 15 Class B. The system is certified to UL 3141 and listed to the UL 1741 PCS CRD for three power control functions: Power Export Limit, Busbar Overload Control and Feeder Conductor Overload Control. PCS functions are set during commissioning, which needs a qualified person and a password. To recommission a system, contact Generac PWRcell technical support so they can reset it.

review note: support check: partial - The footnote says settings are based on an apparent power rating of 11500 VA, but it doesn't call this the rated power of the PWRcell 2 as a whole.
