For some personal reasons she is not ready to evacuate I do not expect anyone to agree with my logic and I know this does not answer your question but the only responsible answer in my opinion would be to do what you can to help her get past the personal reasons. Any technological answer anyone here could give would just make her a target. Satellite phone or computer terminal? Target. Generator? Target. Portable solar generator and panels? Target. In my opinion she needs to grab anyone and anything that can not be replaced and relocate. I would even further add that nobody should expect to go back to Ukraine for at least a decade based on historical patterns. Perhaps your company could expense and write-off her travel and first few months rent somewhere?
