Solms was born in Utrecht. A cousin of William of Orange, he served in his armies during the various wars against Louis XIV of France.

In 1688 Solms accompanied William during his invasion of England as part of the Glorious Revolution. It was a contingent of the Blue Guards under his command that first entered London to secure it for William. He again accompanied Orange, now declared William III of England, during his Irish campaign of 1690. He took part in the Battle of the Boyne, a decisive victory over the Irish Army of James II.

When William departed for England after the unsuccessful Siege of Limerick, he left Solms in command of his army in Ireland. However the Count turned down the offer to lead it during the coming campaign and he was replaced by another Dutchman Godert de Ginkell, 1st Earl of Athlone.

Solms then served with William as part of the Grand Alliance forces fighting in the Low Countries. Commander of the Garde te Voet, he played an important role in the Battle of Steenkerque in 1692. The following year was killed at the Battle of Landen.
