LED next to "RDY"
LED lights up red. The Meter Box is defective.
Corrective measures:
• Contact the SMA Service Line.
LED next to the
"PV-Meter" jack is
out for more than
10 seconds. Reading head/PV production meter is not transmitting data continuously.
Corrective measures:
• Check whether the PV production meter is displaying a value.
If the PV production meter displays a value, the reading head may
not be connected correctly or may be defective:
– Make sure that the plug of the reading head or of the extension
cord has been correctly inserted into the "PV-Meter" jack.
– Make sure that the plug of the reading head and the plug of the
extension cord have been correctly inserted into the designated
jacks (see Section 6.3.3).
– Make sure that the reading head of the PV production meter is
aligned correctly. Here, slowly turn the reading head of the
PV production meter clockwise until the LED next to the
"PV-Meter" jack starts flashing (see Section 7).
– If the LED next to the "PV-Meter" jack does not flash, replace the
reading head.
