The Huawei SUN2000-100KTL-USH0 is a string inverter from Huawei, and its user manual calls it the SUN2000. Its maximum efficiency is 99.00 percent and its CEC efficiency is 98.50 percent. Rated output current is 72.9 A. Before connecting strings, use a multimeter to confirm that the DC input voltage does not exceed 1500 V and that the polarity is correct, or the inverter can be damaged. If a string is connected with reversed polarity while the DC switch is on, do not switch off right away. Wait until the string current falls below 0.5 A, then fix the wiring. Use only the Staubli MC4 terminals and connectors supplied with the inverter. Damage caused by incompatible connectors is not covered by warranty. The inverter supports PLC and RS485 communication, but only one of the two can be used at a time. The manual lists FCC Part 15B, FCC Part 15G and CSA compliance marks for the inverter.

max_input_voltage

c7 drafted · lead ≤ 1500 V

Conditions: DC voltage at the DC input terminals, checked with a multimeter before connecting strings

review note: support check: partial - 1500 V is a limit not to exceed in the DC voltage check; the passages don't call it the max input voltage spec explicitly, though strongly implied.
