Quick answer

If your factory stops at night, compare current generation, connected machine demand and stored energy. A daytime solar rating does not establish all-night operation. Three published guides report a Pressure Chamber at 10 kW and a Stone Press at 18 kW; one of each therefore needs 28 kW before other loads. These are guide-reported values, not measurements by this site. S23S26S27

Add the connected loads

Equipment Reported reference value How to use it
Solar Post 3 kW generation Multiply by count for a rated-output comparison
Solar Twin (M) 7.5 kW generation Compare with actual generation at the time of the fault
Pressure Chamber 10 kW demand Multiply by active machine count
Stone Press 18 kW demand Multiply by active machine count

With those defaults, processing load = 10 × Chambers + 18 × Presses, in kW. Add any other loads shown by your game. Replace the reference values if your build, upgrades or Mods show different ones.

Processing setup Reference load Solar Twin count at 7.5 kW each
1 Chamber 10 kW 2 give 15 kW rated
1 Press 18 kW 3 give 22.5 kW rated
1 Chamber + 1 Press 28 kW 4 give 30 kW rated
1 Chamber + 2 Presses 46 kW 7 give 52.5 kW rated
2 Chambers + 5 Presses 110 kW 15 give 112.5 kW rated

Counts round up the reference load divided by 7.5. They describe rated arithmetic only; actual solar output, other equipment and battery charging can require more. In particular, two Twins provide 15 kW, which cannot cover a 28 kW Chamber-and-Press pair. The GAMES.GG article's later expansion wording conflicts with its own listed numbers. S26

Check power at the machine

  1. Read the stopped machine's status and confirm its two material stages are not simply empty or blocked.
  2. Inspect the power connections and whether the intended generator or storage is part of the same supplied setup.
  3. Record actual generation, connected demand and battery charge at that moment.
  4. Compare during daylight and again after sunset without adding machines.
  5. If power is available but production still stops, inspect Chamber input and output or both Press inputs.

Use the game's power indicators and connection prompts. This guide does not invent a cable-distance limit or a particular physical port location.

Why batteries do not fix every shortfall

Storage must be charged before it can cover a generation deficit. Adding storage to a factory that already consumes all available daytime output does not itself create charging surplus. Compare charge before sunset, demand while solar output falls, and whether charge falls as the machines continue running. S23S27

Power in kW is a rate; stored energy in kWh is an amount. If your interface explicitly supplies usable kWh, an ideal estimate is usable kWh ÷ unmet load in kW = hours. For example, hypothetical 56 kWh at a constant 28 kW deficit gives 2 hours. That is a unit example, not a documented battery capacity or two hours of game-time autonomy. Without verified storage units, losses and night duration, this site does not give an exact battery count for overnight production.

Expand after one day-and-night comparison

Check the observed load and charge behavior before adding another Press. Keep the factory material paths working and compare completed output over the same interval. A Mod that changes power use or battery behavior needs its own calculation; use the Mod guide to keep it separate from vanilla values.
