Hi, I’m having this extact same issue, same setup - RCT 1kva, with 2x 100ah, have been running this for the past year now. Load is 80-100w. Today during the latest load shedding spell I noticed I got an hour’s use before it switched off. After the power restored, the batteries displayed they fully charged in a few minutes. @PixelZADid you manage to find/ resolve the issue?
