+Wattson's Wisdom: The Death Rule
If it can kill you instantly, pay a professional. Your family needs you alive more than you need to save $500. 240V AC across your heart stops it instantly. No YouTube video prepares you for that.
DIY Solar Safety: Deadly Mistakes That Kill
Every year, 47,000+ house fires start from electrical problems. 73% of electrocution deaths happen to people working on "simple" connections. Here are the five deadliest DIY solar safety mistakes:
⚡ 1. Live Wire AC Connections
What happens: Connecting inverter to main panel with breaker on. 240V AC across chest.
Result: Cardiac arrest, permanent heart damage, death.
🔥 2. Improper Grounding
What happens: Skipping grounding rod to save $200. Lightning has nowhere to go.
Result: House fire, $150,000+ damage, family displacement.
💥 3. Battery Bank Wiring Errors
What happens: Mixed battery types, wrong wiring configuration. Thermal runaway.
Result: Lithium battery explosion, toxic gas exposure.
⚠️ 4. Structural Installation Failures
What happens: Roof-mounted panels without structural analysis. High winds.
Result: Panels become missiles, lawsuits, insurance denial.
📋 5. Code Violations
What happens: "Stealth" installation without permits. Inspector finds it during sale.
Result: Complete removal required, sale falls through.
"Your DIY solar safety guide saved me from making a deadly mistake. I was about to connect my main panel myself. Now I understand why that's a job for licensed electricians. Hired a pro for that part, did everything else myself."

- Interior cable runs - Running cables through walls
Estimated savings: $3,000-8,000
⚠️ YELLOW ZONE: Proceed with Caution
- Battery bank assembly - Series/parallel connections (with training)
- Charge controller programming - Complex settings
- Ground mount installation - Concrete work, basic structural
- Inverter installation - Location and ventilation critical
Requirements: Electrical training, proper tools, safety protocols.
🚨 RED ZONE: Professional Required
- Main panel connections - 240V AC will kill you
