Thats normal even for generators, its because each popsicle fridge takes up two tiles, so it calculates it for both pop fridges even if theres only one, since it takes up two tiles.

2x Pops = 144 Ah -> x=72 Ah (One two tile fridge)
4x Pops = 464 Ah -> x=116 Ah (Two two tile fridge)
6x Pops = 1040 Ah -> x=173 Ah (Three two tile fridge)

It doesn't seem normal or make sense to me

Yeah, faulty code. Should be updated.

It does not seem this was ever fixed. Based on the consumption values in the wiki - https://github.com/radx5Blue/ImmersiveSolarArrays/wiki/Estimating-power-production-and-consumption

My output is way higher than what it should be. I have 24x lamps, 1x fridge and 2x pop fridge. My output should be 458.16, but it's over 691 according to the battery bank. This seems like a really weird thing to be happening and I'm not entirely sure why the consumption of multi-tile fridges wasn't taken into consideration beforehand. Standalone freezers are much more energy efficient than a modern refrigerator. At the very least the power consumption for multi-tiled fridges should be cut in half. Instead of 2x pop fridge taking over 147.2, it should be 73.6 for both.
