unilhexio Posted October 16, 2012 Share Posted October 16, 2012 Hi!I have detected the following possible bug: when exporting to a file the Energy injected into Grid (hourly data) I obtain these values (for example):30/11/1990 4:00 030/11/1990 5:00 030/11/1990 6:00 030/11/1990 7:00 13796530/11/1990 8:00 44176130/11/1990 9:00 68336130/11/1990 10:00 86694630/11/1990 11:00 113108830/11/1990 12:00 82455430/11/1990 13:00 44496330/11/1990 14:00 36495730/11/1990 15:00 43090130/11/1990 16:00 13510130/11/1990 17:00 -3247.810230/11/1990 18:00 030/11/1990 19:00 030/11/1990 20:00 0namely, there are values below zero although "night disconnect" is marked in external transformer detailed losses (ohmic losses). This occurs randomly and always in the beginning and final hours of a day. I have realized this problem at least from version 5.57.Moreover, the total sum of Energy Injected into Grid including negative values, is employed in order to calculate the performance ratio and the specific production of the PV Plant.Is this a real Bug or am I doing something wrongly?Kind regards.
