The CPS SCA25KTL-DO/US-208 is a transformerless three-phase string inverter from CHINT Power Systems, built for 208 VAC grid connections. It takes up to 1000 VDC at the input, runs over a DC operating range of 200-950 VDC and starts at 330 V and 80 W. Its MPPTs can run independently or be combined in parallel. It delivers up to 69.5 A at 208 VAC and 60 Hz, with current THD below 3% and a maximum efficiency of 97%. Its listed smart-grid functions are voltage and frequency ride-through, ramp-rate control, specified power factor, Volt-VAr, Freq-Watt and Volt-Watt. You can select the IEEE 1547a2014, CA Rule 21, ISO-NE or HECO grid standard. It has DC arc-fault protection on an arc board. If you see Arcboard Err or ARC Protect, check that the logic connector to the arc board is secure and run the Arc Fault Test from the Settings menu. It communicates over RS485, and you load firmware upgrades through a USB port.
<!-- review notes
- sentence 1: support check: partial - Transformerless and 208VAC are supported, but 'three-phase', 'string inverter' and the full CHINT name are not stated.
- sentence 6: support check: partial - RS485 is supported; the USB port caption for firmware upgrades supports the USB firmware loading, but only as a figure caption.
- sentence 1: review: partial - The passages support transformerless and 208 VAC, but they never say three-phase, string inverter or CHINT Power Systems.
