Duplicates

In 2020.2.29.r2.ssc.240, this inverter is repeated twice on line 15954:

Silfab Solar Inc. SIL370MT-W,Silfab Solar Inc.,Mono-c-Si,0,372.783,340.2,1.9,,,72,9.93,48.2,9.39,39.7,0.005263,-0.135442,47.5,1.84325,9.93565,4.33E-11,0.306649,538.957397,8.703145,-0.368,N,SAM 2019.12.19,12/19/2019
Silfab Solar Inc. SIL370MT-W,Silfab Solar Inc.,Mono-c-Si,0,372.783,340.2,1.9,,,72,9.93,48.2,9.39,39.7,0.005263,-0.135442,47.5,1.84325,9.93565,4.33E-11,0.306649,538.957397,8.703145,-0.368,N,SAM 2019.12.19,12/19/2019

However, there is no "Silfab Solar Inc. SIL370NT-W" CEC Module, and all of the other module nameplates, EG: 360W, have 4 variations: "MT", "MT-W", "NT", & "NT-W" each with identical parameters. A Silfab manual states technology as the difference between "MT" and "NT", but does not explain "-W" suffix, which might indicate it was added by NREL. Therefore the repeat, is renamed as "SIL370NT-W" to complete the family.

Manually correcting bad characters. Check the pvfree.log file using Azure SSH client in the portal. Use grep Failed pvfree.log -C 1 to find upload failures. Then manually edit the bad entries in the original file and upload again.

Schneider 2018.11.11.r3-r4

The Conext CL-NA 18kW and 25kW inverters have a voltage range 422[V]-528[V] in the SAM database which can't be parsed as a float, but the nominal voltage is given as 480[V].
