I ran into the same issue last year when I was setting up a mobile genetics lab for field use. We were traveling between sites, and I needed stuff that could handle being off-grid part of the time. I started digging into more compact and lower-consumption models — even stuff like chillers and microscopes can vary a lot in power use. I ended up finding a few good choices by browsing through https://gentaur.co.uk/laboratory-equipment/ , and some of their newer lines are way more efficient without losing performance.
