Illustration 6.25: Data Overwrite 6.7.8. Plant Status [0] [Plant] Check 'Enable' to activate a plant status e-mail on a daily, weekly or monthly basis. The e-mail contains important information about the energy production of each PV input (PV string) and each inverter. This can help discover failures due to soiling, partial failure of solar cells, or a faulty inverter circuit. Illustration 6.26: Plant Status Example In this example, the recipient ‘test’ receives a daily e-mail, with the following notifications: • INVERTER PRODUCTION DEVIATES MORE THAN 5 % When the energy produced by an inverter within the plant deviates more than 5 % compared to the total average of the plant, the report shows the inverter name. Note that the plant must contain more than one inverter, to obtain this notification. • PV PRODUCTION DEVIATES MORE THAN 3 % When a PV string within a specific inverter deviates more than 3 % compared to the average of the inputs on this inverter, the e-mail reports the name of inverter and PV input. Note that a minimum of two individual PV inputs must be activated on the inverter, to obtain this notification. For example, two individual inputs are adequate but two inputs in parallel are not. 6.
