Thankfully 99% of the time slides won't operate regardless of type is due to defective battery/batteries. Slides work off the batteries even if plugged into shore power. Just went through this on 2 different RV's. Was at a Campground recently in our Montana 3901FB and brakes quit working just before arriving. Upon set up, difficulty with slides.
Basically everything goes through the battery. I had a Volt Meter and battery read 12 Volts but it was a cheapo meter that would not read Amps. Took battery to O'Reilly's for a quick Charge and Load on it and battery was defective. Bought new battery and everything worked perfectly.
Hope this is your problem B4 you spend thousands on a Tech replacing your Control Panel, replacing Inverter, Troubleshooting, etc.
Hope this helps.
