Getting out before the storm.

How to finish the mission on the second day. It is assumed that you done the tutorial, made at least one attempt at the mission, and understand the basic game mechanics. Surviving the storm is probably a lot more fun than just winning quickly.

First Day

As soon as the mission starts, ignore the instructions and race to the base and build a medium solar panel, you should already have the parts. Disconnect one of the small 5kw panels, preferably the one nearest the habitat and connect the cable to your new medium panel.

Go to the transformer control and send 100% of the power to the battery. Disconnect battery output, which is currently feeding the crusher, drag the cable over to one of the medium panels near the crusher and drop it on the ground so it is ready when you actually need to power the crusher.

Disconnect the well power cable from the transformer and plug it into the unused small 5kw panel. This will give the well enough power to run the oxygen generator during the day. Go ahead and connect the oxygen from the well to the habitat, it should get you through the first night. Disconnect the habitat power cable from the transformer and connect it to the battery output, then run to the habitat and get your potatoes planted in the hydroponics table. You may want to use the power console to power down the plant incubator, it won't save much though.

Return to the mission and follow the instructions but be sure to break up enough ore to fill the trailer when you break up the large rock. Drive onto the crusher then disconnect the medium solar panel and use it to power the crusher. Dash back and empty the trailer, grab some water and oxygen from the rover locker while it empties, hydrate and eat some rations.

Start printing the battery parts as instructed, or better yet, two of them. Collect the printed parts along with the iron from the shredders inventory. Run over to build your new battery next to the old one. Disconnect the power from the old battery and connect it to the new one. Run a new cable from the new battery output to the input of the old battery so they are connected in series. Disconnect the shredder from the solar panel and re-attach the cable running to the transformer.

You and your potatoes should be all set to make it through the first night, you may run out of power before the sun rises but it’s not going to cause any real problems for your potato crop which should be ready at the end of the second day. Hopefully, you should still have plenty of time to drop off the iron from your backpack inventory into the container then head south to the old base and pick up the tablet as instructed. If you still have time, make a start on fixing the board, but you will have plenty of time to finish on the second day. Drink some water from the bathroom tap, eat some rations and go to bed.

Second Day

Don’t worry if the power is out, it will come back on soon. Save the game. Get into the rover and drop off the ore trailer and pick up the container with the iron. Drive over to the well and disconnect the well oxygen pipe from the habit, drag it over to the rover and connect it there. Then connect one of the unused transformer outputs to the rover. Divert 50% of the power to charge the rover. Return to the habitat, which should be powered properly by now. Turn on the internal oxygen supply, full power if you like, there should be plenty of energy available. Finish up repairing the circuit board, go to the bathroom for a drink, eat something then go back to bed, set the alarm for 17:00 so you are well rested for you trip home. Wait for the potatoes to finish growing then harvest them. It will probably be dark by the time you have done that, so turn on your flashlight and run to the rover, disconnect the power and oxygen. If it’s complaining about unpowered buildings, plug the shredder into the second battery. Return to the rover, turn on the headlights and drive to the extraction point.

Alternatively, you can defer charging up the rover until the afternoon and charge it using 70% of the power. This lets you use the day more productively to gather more ore and build up the base. Remember to close the rover door if you want to wait for the storm.

Power and Oxygen

Batteries

It would be nice to know if batteries are 100% efficient, if not its probably best to avoid chaining them in series. It works fine for demo though.
Looking at the specs it seems that the batteries are perfectly matched for a medium solar panel. So the intended set up is probably:
Medium Solar Panel > Battery Pack > Transformer
Three of these feeding a transformer should provide a good power source for both the habitat, and the rover when it needs to be charged. A single small panel will keep the well making oxygen during the day and a medium solar panel will keep the shredder running.

Example Habitat Power Supply

The thee medium solar panels can supply 90kw for 12 hours each day, providing the habitat with 45Kw over 24 hours. The minimum power needed to run the Habitat is 30kw which leaves 15kw to charge up the batteries fully over two days. You can also hook up the spare small panel for an extra 5kw during the day, this should be enough to prepare you for the first storm, but it will be tight if you are also using the O2 Scubber. Adding an extra medium solar panel will let you run the Scubber at full power and charge up the system quickly.

I'm not sure how much you can trust the read outs from the batteries and transformer. While changing the system up the batteries attached to the panels show only 5KW until the main battery pack is fully charged.
This makes no sense at all, after a short time they should be providing 30kw each for a total 90kw. The chain of three batteries that follow the transformer do seem to charge up in the expected 6 hours at which point the other three batteries quickly start to charge and report the expected power levels.
At this point the main battery pack was fully charged and there was actually zero power going though the transformer, the numbers just show the power available.
With fully charged batteries, the transformer can charge up your rover really quickly.

Storms seem to take about 12 hours usually, so the worst case is 36 hours of darkness. With the O2 Scubber on, each battery can supply the habitat with power for roughly 5 hours, so six batteries + the internal battery in the habitat gives 35 hours. A single hour without power won't be too serious, but a 4 panel, 8 battery system is a good upgrade when you get the resources.

Habitat O2 Generator

The valves on either side seem to increase the O2 generated and the two in the middle the cooling. It kind of feels more Boeing than SpaceX, so you may want to quick save before you mess with it.
