Okay, that's exactly where you need to be.
Now click on the backpack button, and start adding capacity (blue) camp equipment into the empty slots. There should be a selection option at the bottom of your screen to limit the inventory equipment that is displayed to just blue items or just green items.
Your night configuration should have maybe 75% blue equipment and 25% green equipment. But this really depends on how much equipment you have, how strong the equipment is, and how much time will go by before you use the game the next day.
So, just as an example, let's say a) you put in enough (green) regeneration equipment to generate 1,000 energy per hour, and b), you will not be using the system again for 10 hours. That can support 10,000 in (blue) capacity equipment.
1,000 energy/hour times 10 hours = 10,000 capacity equipment needed
But it's really up to you how you want to balance your blue equipment with your green equipment.
Pull down the green energy bar statistics to check the calculations for your current setup. Keep adjusting the equipment until you're satisfied with how much energy you will be able to generate and store overnight.
