Is the rapid shutdown product (TS4-A-F) more robust than the optimizer product (TS4-A-O)?

    I don't know if "robust" is the right word. The decision to use the TS4-A-F over the TS4-A-O should be based on the project application. Since rapid shutdown is mandatory in the US for all rooftop installs, then it boils down to whether the customer wants to optimize the system and enjoy all the benefits of module level monitoring (TS4-A-O), or if a rapid shutdown only (without optimization and monitoring) is the goal.
