Transform your battery rack from “hidden in a corner” to “front‑and‑center showpiece” while adding a useful safety cue. In this build, I add a bus‑energized LED strip to my 60kWh home battery rack so it only lights when the DC bus is live—instantly telling you the system is energized. It’s a quick, modular DIY using a buck converter + LED controller, with an optional path to WLED/SOC logic later.
What you’ll see:
How the LED indicator works as a visual “bus live” safety cue
Parts list and simple wiring: battery bus → buck → LED controller → LED strip
Modular connectors, soldering tips, and clean cable management
Testing, remote control, and ideas for upgrading to WLED/SOC in the future
Parts (or equivalents):
Addressable LED strip (single run split across two racks)
LED controller (simple RF today; WLED-capable if you want smart later)
Buck converter (drops pack/bus voltage to LED strip voltage)
Connectors, ring terminals, heat‑shrink, wire, adhesive mounting
The Parts List!
BTF-Lighting FCOB WS2811 IC 864LED 24v LEDS - amzn.to/4olYcA7
BTF-Lighting SP530E LED Controller - amzn.to/3W00UPA
48v (60v max) to 24v Buck Converter - amzn.to/4nQmjqI
Alternative LED WS2814 RGBW (used in my house) - amzn.to/4qdIIjm
Heat Shrink Tubing - amzn.to/4ojEyom
Kester Solder - amzn.to/42ECGOv
My current favorite WLED Controller - amzn.to/439Ls7i
Notes:
The LEDs only illuminate when the bus is energized—great for status at a glance
Future upgrade: drive colors/animations by battery SOC with WLED
Always follow electrical safety best practices around high‑energy DC systems
