An AC/DC clamp reads direct current through the jaw as well as alternating current, so it works on solar arrays, battery banks, inverters, golf carts and car electrical systems. Clamps here top out at 400 to 600 A. Check the CAT rating against your work: several of these are rated only CAT III 300 V, fine for vehicles and household circuits but not for commercial panels.
