Legal & High-Voltage Safety Disclaimer
Please review these critical safety warnings before probing electrical terminals, performing component replacements, or executing hardware resets.
High-Voltage Electrocution & Arc Flash Hazard
Troubleshooting solar inverters, electric vehicle battery packs, high-voltage heat pumps, and power supplies involves hazardous potentials exceeding 600VDC / 400VAC. Direct contact with uninsulated circuits can result in severe physical injury or death. Only qualified, certified technicians equipped with Category III/IV 1000V rated multimeters and insulated PPE should open high-voltage enclosures.
