About Watt & Wrench

DIY home power, backup, and energy upgrades - with real parts lists. We publish build guides, comparisons and parts lists for solar, battery backup, generators, EV charging and the tools around them.

Affiliate disclosure

Watt & Wrench is reader-supported. When you buy through links on our site we may earn an affiliate commission at no extra cost to you. We participate in affiliate programs including Signature Solar and Amazon Associates. Links marked "Check price" or found under /go/ are affiliate links. This never affects what we recommend: the commission rates are similar across retailers and we lead with the parts we would buy ourselves.

Safety

Electrical work can kill you and burn your house down. Follow the NEC and local code, pull permits where required, and hire a licensed electrician for anything touching your service panel or utility interconnection. Our guides are educational, not a substitute for a professional.

Privacy

What we collect, why, and how to have it deleted: read the privacy policy.
