Dear, I would like to know why the energy generated in simulations with microinverters and optimizers is sometimes less. Example: 1 - System of 6 PV modules of 360Wp each, with Tigo A-O optimizer. In situations without or with little shadows the system with optimizer has lower performance. This happened with microinverter as well. Is this due to efficiency? In other software the result is slightly higher 1% ~ 3%. Att,
