Yes, a good engineer would have test equipment with him/her and.....know
how to use it. However realize these service people are just trained
monkeys - not to be derogatory, but they are not trained in technical
matters. Solar Edge would have to invest time and $$$$ for them to be
effective at a technical level. They are trained only to the level of
following directions.
