If your Metal Farm keeps showing the annoying “Power Systems Offline” warning in Subnautica 2, you’re definitely not alone. A lot of players hit this problem the moment they start building larger automated bases. Everything looks connected, your Power Transmitters seem fine, and yet the Metal Farm still refuses to stay online.
The good news is that this usually isn’t a bug. In most cases, your base simply isn’t producing enough power to handle the massive energy drain from a Metal Farm.
Here’s exactly how to fix the Metal Farm power issue in Subnautica 2 and build a stable long-term setup.
Why Your Metal Farm Keeps Going Offline in Subnautica 2
The main reason your Metal Farm stops working is simple: Metal Farms consume a huge amount of continuous energy.
Many players try powering them entirely with Solar Modules, but solar power becomes unreliable once:
- nighttime starts
- your base is too deep underwater
- multiple machines run at once
- storage systems and fabricators are active
That causes your overall power grid to collapse temporarily, triggering the “Power Systems Offline” warning.
Even if your base works during the day, the Metal Farm may still shut down at night because solar generation completely stops.

Do Power Transmitters Fix Metal Farm Power Issues?
No — and this is where many players get confused.
Power Transmitters in Subnautica 2 do not generate electricity. They only transfer existing power from generators to your base.
So if your generators already lack enough output, adding more transmitters will not solve the problem.
However, transmitters are still important if:
- your generators are far away
- you’re using Thermal Plants
- you’re using Hydroelectric Turbines
- your base spans multiple compartments
In most cases, you’ll need several transmitters chained together for stable long-distance power transfer.
Best Power Source for Metal Farms in Subnautica 2
If you want reliable Metal Farm automation, you’ll eventually need stronger generators than Solar Modules.
Here are the best power sources currently recommended by the community.
Hydroelectric Turbines
Hydroelectric Turbines are currently one of the best ways to power a Metal Farm in Subnautica 2.
They generate steady energy from underwater currents and continue working day and night.
Why players use them:
- constant power generation
- excellent for large bases
- reliable long-term solution
- works better than solar for industrial setups
Most late-game players run multiple turbines connected through Power Transmitters.
Thermal Plants
Thermal Plants are another excellent option if your base is near geothermal vents or volcanic areas.
They provide stable passive energy with almost no maintenance.
Benefits:
- reliable deep-water power
- unaffected by nighttime
- perfect for permanent bases
- excellent backup for Metal Farms
If you’re building in deeper biomes, Thermal Plants are usually much more reliable than solar panels.
Bioreactors
Bioreactors are useful during the early and mid-game.
While they may not fully sustain multiple Metal Farms alone, they help stabilize your power grid and prevent shutdowns during peak energy usage.
Bioreactors work especially well alongside:
- Solar Modules
- Power Storage
- Thermal Plants
Why Solar Panels Struggle With Metal Farms
Solar Modules are great for starter bases, but they’re one of the weakest long-term power solutions for automation-heavy setups.
Solar becomes less effective when:
- your base is deeper underwater
- weather conditions reduce efficiency
- nighttime begins
- too many systems draw power simultaneously
This is why many players experience random Metal Farm shutdowns despite having “lots” of solar panels installed.
Best Early-Game Metal Farm Power Setup
If you’re still early in Subnautica 2, this setup works well for a single Metal Farm:
- multiple Solar Modules
- one or two Bioreactors
- several Power Storage units
- properly connected Power Transmitters
This hybrid setup helps smooth out power spikes while giving you backup energy during nighttime.
Add Power Storage for Stable Energy
One of the most overlooked fixes is adding Power Storage modules.
These act like batteries and help stabilize your grid when the Metal Farm suddenly draws large amounts of energy.
Without Power Storage:
- your grid fluctuates constantly
- solar-only systems become unstable
- Metal Farms may repeatedly shut down
Adding storage often fixes intermittent offline warnings instantly.
Quick Fix Checklist for Metal Farm Power Problems
If your Metal Farm still won’t work, check these issues:
Is your base too deep for solar efficiency?
Solar power weakens significantly at deeper depths.
Are your solar panels shutting off at night?
Solar Modules stop generating energy completely after dark.
Do you have enough total power generation?
Metal Farms require far more energy than most starter bases produce.
Are your Power Transmitters connected properly?
Long-distance generators usually require multiple transmitters chained together.
Does the warning disappear when the Metal Farm is disabled?
If yes, your generators simply can’t keep up with the energy demand.
Final Thoughts
The “Power Systems Offline” warning in Subnautica 2 usually comes down to insufficient energy production rather than a broken Metal Farm.
While Solar Modules work early on, most players eventually switch to:
- Hydroelectric Turbines
- Thermal Plants
- Bioreactor hybrid setups
- additional Power Storage modules
Once your base has a stable power grid, your Metal Farm should run continuously without shutdowns.
At the moment, the community consensus is pretty clear: if you want reliable Metal Farm automation in Subnautica 2, solar-only setups just aren’t enough anymore.
FAQ
Why is my Metal Farm offline in Subnautica 2?
Your base likely does not produce enough power to sustain the Metal Farm continuously.
Do Power Transmitters generate electricity?
No. Power Transmitters only transfer power between generators and your base.
What is the best power source for Metal Farms?
Hydroelectric Turbines and Thermal Plants are currently considered the best long-term solutions.
Can Solar Panels power a Metal Farm?
Yes, but usually only temporarily or during early-game setups. Most players eventually need stronger generators.
Why does my Metal Farm shut down at night?
Solar Modules stop producing power at night, causing your energy grid to fail if no backup generators exist.
