It won't have life if it doesn't have access to outside energy. That much is certain. The way that we can "cheat" the 2nd law of thermodynamics is that there is energy separated into different systems that can leak or affect other systems. Gravity and QM help create the sun and the conditions that separated the earth from the huge amount of energy being produced by the sun. There it creates a separate system within a much larger system (the universe) that can have increased entropy.
An eclipse is not an example of a closed system as it is only blocking part of the Sun's energy not all of it. It is a reduction in energy not an absences of it. As I said there are gravitation forces that are never removed if the Sun or any other massive body is in proximity to the Earth. Without placing Earth in a completely closed system it is still an open system. There is no example of such a body we have found at this time. Consider the theory that stars are formed within nursery nebula so even without a star it is not a closed system as even the matter within the nebula form new starts due to gravity. Hence population I, II and III stars.
