Most Rust players cobble together a solar panel, a battery, and a wire — and call it a day. It works, kind of. The lights stay on most of the time, the battery drains overnight, and eventually you log back in to find half your base dark and your turrets offline.
The Infinite Power Loop fixes all of that. It's a self-regulating circuit that automatically switches between solar power during the day and battery power at night, keeps the battery topped up whenever the sun is out, and never lets your base go dark — all without a single manual switch or timer.
Once it's wired and the numbers are dialled in, you forget it exists. That's the goal.

How It Works — The Big Picture
The circuit has two modes that switch automatically based on whether your power sources are generating enough electricity:
☀️ Day Mode — Solar panels (or wind turbines) produce power. That power flows directly to your base devices through the A/B switch. Any surplus power charges the battery. A Blocker component prevents the battery from discharging into the circuit while solar is active, protecting the charge.
🌙 Night Mode — Solar output drops to zero. The Blocker loses its trigger signal and opens up, allowing battery power to flow through to the A/B switch. Your base stays powered from the stored charge. The switch flips to the battery side automatically.
The loop is "infinite" because as long as your daytime generation exceeds your nighttime consumption, the battery never runs dry. You never touch it again after setup.

What You Need — Component List
This is the minimum component list for the basic circuit. Everything below is craftable at a Tier 1 workbench or found at monuments.
| Qty | Component | Role in the Circuit | Craftable? |
|---|---|---|---|
| 1+ | Solar Panel | Primary power source. Outputs 0–20rW depending on sun angle and weather. More panels = more power. | Yes (T1 WB) |
| 1 | Large Battery | Stores up to 100rW capacity. Outputs up to 100rW. The nighttime power reserve. | Yes (T1 WB) |
| 2 | Electrical Branch | Splits the power line. Branch 1 diverts power to your devices. Branch 2 diverts to the Blocker and battery. | Yes (T1 WB) |
| 1 | Electrical Blocker | The automatic switch. Blocks battery output during the day. Opens at night when solar drops. | Yes (T1 WB) |
| 1 | A/B Switch | Routes either solar path (A) or battery path (B) to your devices based on which input is receiving power. | Yes (T1 WB) |
| 1 | Wire Tool | Required to make all connections. Hold to connect outputs to inputs. | Yes (T1 WB) |
| 1+ | Root Combiner (optional) | Merges multiple power sources into a single line. One Root Combiner per pair of sources. Red type only. | Yes (T1 WB) |
Root Combiners are Red only. The game has two combiner types — the Red Root Combiner is for power sources like solar panels and batteries. Blue combiners are for signal logic. Only use Red here or your circuit won't work correctly.
Step-by-Step Wiring Guide
Place all components near each other before wiring — spacing doesn't matter for function but keeping them close makes it easier to see what connects to what. A good spot is inside a dedicated "electrical room" in your base away from rain.
Place and angle your Solar Panels
Place solar panels on your roof in an open area with clear sky. Face them south for maximum output in the northern hemisphere of the Rust map. Each panel needs line-of-sight to the sky — walls and overhangs block output. Run a wire from each panel's Power Out to a Root Combiner if using multiple panels, or directly to Electrical Branch 1 if using a single panel.
Chain your Root Combiners (if using 2+ panels)
Each Root Combiner takes two Power In connections and outputs the combined total. For 4 solar panels: wire Panel 1 + Panel 2 → Root Combiner 1, Panel 3 + Panel 4 → Root Combiner 2, then Root Combiner 1 + Root Combiner 2 → Root Combiner 3. The final Root Combiner's output goes into Electrical Branch 1.
Wire Electrical Branch 1
This branch is the first split point. Connect your power source (Root Combiner or single panel) to Branch 1 Power In. Set the Branch Out amount to how much power you want to send directly to your base devices. The Power Out (whatever's left) continues down the circuit. Start with a Branch Out value of around 60% of your total power — you can fine-tune this later.
Connect Branch 1 to the A/B Switch (Input A)
Wire Branch 1 Branch Out → A/B Switch Input A. This is your "solar path" — the direct daytime power line to your devices. When solar is active, the switch stays on A and your base runs directly off the sun.
Wire Electrical Branch 2
Connect Branch 1 Power Out → Branch 2 Power In. Now set Branch 2's Branch Out to send a small amount (3–5rW is enough) to the Blocker's Block input. The remainder — Branch 2 Power Out — goes directly into the Battery's Power In to charge it.
Wire the Blocker
The Blocker has two inputs and one output. Connect Branch 2 Branch Out → Blocker Block Passthrough input. This is the "lock" signal — when solar is producing, this signal tells the Blocker to block. Next, connect the Battery Power Out → Blocker Power In. Finally, wire Blocker Power Out → A/B Switch Input B.
Connect the A/B Switch to your devices
Wire A/B Switch Power Out to whatever you're powering — a Splitter to fan out to multiple devices, a Smart Switch for remote control, or directly to lights, turrets, and door controllers. This is your clean, always-on power output line.
Test the circuit
During daytime: check that your base devices are receiving power from the A side. Check the battery is reading "Charging" in the inspect panel. At night (or cover your solar panels with a sign to simulate night): the Blocker should open, the switch should flip to B, and battery power should flow to your devices. If it works — you're done.
Real World Example: Full Base Power System
The circuit above shows the core logic. In practice, a real base uses multiple power sources feeding into the loop and multiple output branches tapping off to different systems. Everything stays the same — you just add Root Combiners on the input side and Electrical Branches on the output side.
Here's how it looks built out with a Wind Turbine, Solar Panel, and five output device groups — the three-stage approach: inputs → infinite loop → outputs.
Keep Branch 1's output generous. In this example, 95 rW comes in. If your devices need 21 rW total, set Branch 1 to around 35–40 rW — giving yourself headroom above device needs so the remainder still charges the battery comfortably at night.
The most common question: "How do I know how much to set Branch 1's output to?" Here's the simple math.
First, figure out your total power demand — how many rW your base devices consume. Then figure out your total generation. The gap between them is your charging headroom.
⚡ Example: Single Solar Panel Setup
At 5rW charging rate, a full large battery (100 capacity) charges in about 20 in-game minutes of daylight. In Rust, a full day/night cycle is approximately 60 real-world minutes — so roughly 30 minutes of daylight, 30 minutes of night. As long as your 30 minutes of charging beats your 30 minutes of nighttime drain, you're self-sustaining.
The golden ratio: Set Branch 1 to output roughly 50–60% of your total generation to devices. The remaining 40–50% handles the Blocker signal and battery charging. This gives comfortable headroom without starving your devices.
Scaling Up — More Power, More Sources
One solar panel powering a few lights is fine for a small base. But for a full PVE setup with auto turrets, camera systems, door controllers, and industrial equipment, you need real wattage. Here's how the circuit scales:
No Root Combiner needed
1× Root Combiner chain
+ Solar backup panels
Adding Multiple Solar Panels
Chain them through Root Combiners before they enter Branch 1. Two panels go into one Root Combiner. That combiner's output combines with a third panel into a second Root Combiner — and so on. You can scale this to as many panels as your roof can hold. The circuit logic doesn't change — only the input power number increases.
Adding a Wind Turbine
Wind turbines output variable power (up to 150rW) but — crucially — they produce power at night too as long as there's wind. If you add a wind turbine alongside your solar panels, route both through a Root Combiner before Branch 1. The combined output means your battery charges faster during the day and you may not need the battery at all on windy nights.
Multiple Batteries
If your nighttime drain is high, you can chain large batteries in series — the output of Battery 1 feeds the Power In of Battery 2, and Battery 2's output goes to the Blocker. This doubles your storage. You can chain up to four batteries for 400rW total capacity.
Troubleshooting Common Problems
🔴 Base goes dark at night even though battery is charged
The Blocker isn't opening. Check that Branch 2's Branch Out is actually connected to the Blocker's Block Passthrough input, not Power In. If those are swapped, the Blocker never releases even when solar drops. Also confirm the battery Output is wired to Blocker Power In, not directly to the A/B switch.
🔴 Battery never charges
Branch 2 Power Out isn't reaching the battery, or Branch 1 isn't sending any remainder to Branch 2. Check that Branch 1's Branch Out value is less than the total power coming in — if you've set it equal to or higher than input, there's no remainder flowing to Branch 2.
🔴 Battery drains during the day
The Blocker signal is too weak to trigger — the Block Passthrough input requires at least 1rW. If Branch 2's Branch Out is set to 0, the Blocker stays open permanently and the battery discharges alongside the solar. Set Branch 2 Branch Out to at least 3rW.
🔴 Power flickers at dusk and dawn
This is normal and brief — it happens at the exact moment the A/B switch transitions between inputs. It typically lasts less than one second and doesn't affect turret or door operation. If it's causing issues with sensitive components, add a Small Battery inline on the output side to buffer the transition.
Rain reduces solar output significantly — sometimes to near zero. If your server has frequent storms and you're relying entirely on solar, your battery may not fully charge during a cloudy day. Size your battery generously or add a wind turbine as a weather-proof backup source.
Common Device Power Costs Reference
Use this to plan how much Branch 1 needs to output to cover your base:
| Device | Power Draw | Notes |
|---|---|---|
| Ceiling Light | 2 rW | Most efficient general lighting |
| Flasher Light | 1 rW | Good for alerts and indicators |
| Search Light | 10 rW | High draw — use sparingly |
| Auto Turret | 10 rW | Per turret. Power-hungry but essential |
| SAM Site | 25 rW | Very high draw — dedicate a separate branch |
| Door Controller | 5 rW | Per door. Airlocks use 2 controllers |
| Smart Switch | 1 rW | Plus whatever's downstream |
| Computer Station | 1 rW | For CCTV camera network |
| CCTV Camera | 5 rW | Per camera |
| Sprinkler | 1 rW | Each sprinkler serving your farm |
| Electric Furnace | 3 rW | While active — very efficient |
Final Tips From the Field
- Build your electrical room inside your base, not on the roof. Solar panels and wind turbines must be outside — but the Branches, Blocker, Battery, and Switch can all live indoors, safe from rain and griefers.
- Label everything with signs. A small wooden sign next to each component with "Branch 1 — Main Out" prevents enormous confusion when you come back to add to the circuit two weeks later.
- Add a Smart Switch downstream of the A/B switch so you can remotely shut off power to the entire base via RUST+ on your phone. Useful when you're away from the keyboard and an NPC raid is happening.
- Use a Splitter after the A/B switch output to fan power out to three separate lines — one for lighting, one for turrets, one for doors/cameras. This lets you shut off power to one category without affecting others.
- Protect your solar panels from building damage. Place them on a half-floor or triangle foundation jutting out from your roof so NPCs from AbandonedBases events can't walk up and destroy them.
