Goals at either end of the match saw Alfreton win for the first time in four matches by beating Macclesfield.
Defender Dan Bradley fired the visitors into a first-minute lead with a 25-yard left-foot rocket.
However, Macclesfield were gifted an equaliser when Ross Killock brought striker Chris Holroyd down in the box.
Striker Matthew Barnes-Homer converted the penalty but midfielder Nathan Arnold drilled home with three minutes left to seal the win for the visitors.
VIEWS FROM THE DRESSING ROOM
Alfreton Town manager Nicky Law told BBC Radio Derby:
"It was well deserved. We got off to a dream start and then I think we controlled the game.
"I was slightly disappointed with their goal. It was just a bit of a long, hopeful ball forward and we've let the ball bounce in our box and then it was a bit of a scramble and the referee gave a penalty.
"On first reaction, there's probably no argument with that because I didn't really get a great look at it, but as a defender, you can't let the ball bounce there.
"We reacted well against a big side, a big club, so it's credit to our players that they've come here and worked hard, but when we play at that tempo, we're a match for everyone as we've proved again."
