Hi I have had a solar iboost for 2.5 years. Mine didn't work initially and it was due to faulty sender unit(connects to CT clamp). It sounds like the iboost unit is not getting a signal to start using excess solar. As already said check it is clamped on the correct cable. Then do a kettle test. Basically try boiling the kettle and see if it kicks in. Swap the CT direction and try again. This would identify if it's wrong way. You mentioned blue light and bleeping, is this all the time. Can you take a picture of this scenario?
