No I did not change inverter to Litium one. Did not realize it would be specific to lithium.
With that said, here’s the info Carl and Susan asked for.
2018 Montana 3701LK
Progressive Dyn PD4500 series converter with pin switched to LI.
CSW 1012 1000 WATT Inverter, showing 13.4 volts, powering only the refrigerator with Batter disconnect off.

Test 1. Checked lithium voltage (gradually dropping NO on shore power) 13.4 volts. From battery to inverter terminals 13.4 volts. From plug of inverter to any device, powers up.
Test 2. From RV electrical panel, test converter using Volt meter. See screenshots. Name: A5766214-9434-43AF-B7DE-50060F72E0E9.png
