This Battery Saved Me from a $15,000 Rewire!

My workshop had a "peak" problem, not a power problem. At the top of its cycle, my Gweike screw compressor spikes to over 27A—well past what my utility allows. Instead of a five-figure grid upgrade, I used the Zendure SolarFlow 2400 AC+ and an AB3000L battery to buffer those short, high-current bursts. The "brain" of the system is a custom automation I wrote with Claude AI. It monitors my shop’s phases in real-time and tells the battery to feed in exactly enough power to keep the grid-side draw flat. *Check out the gear I used:* Zendure SolarFlow2400AC+: https://zenduredegmbh.sjv.io/PzV9Oz Amazon SolarFlow2400AC+: https://amzn.to/4e5roZE Gweike 3kw Screw compressor: https://www.gweikecloud.com/products/screw-air-compressor?ref=800USDOFF Up to 800$ off! *Get custom PCBs, CNC machining, and 3D printing here:* https://pcbway.com/g/h5w6ua *Video Chapters* 00:00 The Day the Oil Filter Sprang a Leak 00:43 The Math: Why a 3kW Motor Pulls 27A 01:29 Can This Battery Save My Breaker? 01:42 Three Ways to Fix a Power Limit 02:16 Reframing the Problem: Peak vs. Average 02:48 A Word from PCBWay (and my machine-buying habit) 03:21 How Peak Shaving Actually Works 03:52 Giving the Battery a "Brain" with Home Assistant & Claude AI 04:27 The Stress Test: 15 Bar vs. The Grid 05:10 The Reality Check: Conversion Losses & Safety 06:22 What machine trips your breaker? ─────────────────────────────── 🌐 Website: https://theyieldpoint.com 📊 CNC Router Comparison Data: https://cncrouterinfo.com 💬 Join the Community: https://discord.gg/gM3NEm74h6 🔔 Subscribe: https://www.youtube.com/@TheYieldPoint/?sub_confirmation=1 ─────────────────────────────── ABOUT THE YIELD POINT The Yield Point is a hands-on engineering and maker channel focused on CNC machining, industrial machine retrofits, workshop builds, and fabrication projects.
