I've recently found the green light flashing and the red light on on our SMA 4000TL with the message 'Insulation resistance, check generator' on the display.
Checking the ERROROB2.CSV files I can see that this isn't the first time it has errored in this way, it has happened on odd occasions for several months. The most recent events are listed as:
SB 4000TL-20 78 2.1E+09 13/01/2017 09:06 29180 35 Outgoing Info DC Side Insulation resist.
SB 4000TL-20 78 2.1E+09 17/01/2017 09:11 29249 35 Incoming Warning DC Side Insulation resist.
SB 4000TL-20 78 2.1E+09 17/01/2017 09:11 29249 35 Incoming Error DC Side Insulation resist.

SB 4000TL-20 78 2.1E+09 13/02/2017 08:55 29780 35 Incoming Error DC Side Insulation resist.
Is anyone able to offer an explanation and suggest what might need to be done? The installation is five years old and has 21 Canadian Solar panels on three strings.
