Solar Electrical Safety — AC, DC & Shutdown Basics
Non-technical safety basics for homeowners: why DC wiring is not DIY, and what shutdown procedures mean during maintenance.

Respect DC and AC zones
Solar arrays produce live DC whenever the sun shines; only qualified installers should open combiner boxes or touch string wiring. AC-side work also needs licensed electricians.
Know where your inverter AC isolator and DC isolators are, but do not bypass them without training.
