The CPS SCH125KTL-AIO/US-600 is a grid-tied, transformerless three-phase string inverter from the CPS SCH Series, rated 125 kW AC output. It takes up to 1500 Vdc from an ungrounded PV array through 20 DC inputs, and feeds a 600 Vac, 60 Hz grid with a permitted output range of 528 to 660 Vac. Maximum AC current is 120.4 A at 125 kVA or 127.2 A at 132 kVA. Peak efficiency is 99.0% and CEC efficiency is 98.5%. Power factor is above 0.99 and can be adjusted to plus or minus 0.8. Current THD is below 3%. The inverter has no integrated AC disconnect, uses variable-speed cooling fans, and has LED indicators and an app as its user interface. Modbus data mapping is SunSpec or CPS proprietary. Remote diagnostics and firmware upgrades are standard when used with the CPS Flex Gateway. Listed grid standards include IEEE 1547-2003, IEEE 1547a-2014, IEEE 1547.1-2005, IEEE 1547.1a-2015, CA Rule 21, UL 1741 SA and ISO-NE. Alarm codes include CommErr, meaning communication inside the inverter has failed, and ExtFanErr, meaning a cooling fan failure found by visual check.
