Lowe has signed a two-year contract with the Sandgrounders.
Formerly of the Burnley academy, Southport fans will remember Lowe for his performance against them when FC United visited the Merseyrail Community Stadium in a 3-3 draw last month.
Rowe has scored 9 goals in forty-two appearances for FC United.
He signed a permanent deal with FC United in March this year, before scoring a 94th minute 35-yard winner against Tamworth the same day.
Lowe goes straight into tonight’s match squad when we welcome high-flying Harrogate Town.
