Alarme Automático Detector de Baixa Tensão na Bateria LiFePO4

🔋 Missing an automatic transfer switch in your off-grid system? In today's video, I'll show you how I solved the problem of monitoring my LiFePO4 battery discharge without losing peace of mind at night! I created a simple, inexpensive, factory-finished 24V DIY device to alert me with a buzzer when the battery bank reaches 20% charge (approximately 25.7V/25.8V). 🛠️ In addition to showing the step-by-step drilling process in the string box with a hole saw and the electrical connections to the voltage controller board, I also present an alternative scheme using a 220V Torque relay for those with a hybrid inverter or transfer switch, ensuring protection in case of a power outage from the utility company in the middle of the night! It doesn't matter if you have 1, 5, or 10 batteries in your bank, this simple automation will protect your LiFePO4 cells from deep discharge without requiring you to check the BMS app every 5 minutes. 📥 DOWNLOAD THE PROJECT'S ELECTRICAL SCHEMATIC HERE: ➔ [ https://mega.nz/folder/xo4CWIaD#XqGYQ... ] ⏱️ CHAPTERS OF THIS VIDEO: 0:00 Solar generation of the day and consumption of the house in Brasília 0:59 The problem: Lack of peace when discharging LiFePO4 to 20% 2:25 Introducing the project parts (Buzzer, Button and Board) 4:40 Solution with Torque Relay for those who use a transfer switch 06:01 Marking and drilling with a hole saw on the String Box 14:50 Assembly and finishing of the buttons (Surgical precision!) 18:16 Wiring and soldering diagram 20:00 Practical test of the alarm simulating cloud passage and disconnecting strings 24:48 Fine-tuning of voltages on the board (P0, P1 and P2) 26:22 What went wrong with the blue button?
