Hello forum - first post here.
I have a customer with a 30kW installation (8+ years old) with 2 x inverters (1 x SAMILPOWER SolarLake 15000TL and 1 x Solis Solis-15k). Below are some traces from the generation output. On a good day, all looks as expected (although not quite 30kW, despite panels recently being cleaned). However, on some days the output gets very choppy. Seemingly not because of cloud.
Does anyone have any ideas on how to check what's going on? We have 5-second data being logged via CT clamps.
Here is the past 10 days.
This is a 'good day':
And this is a questionable one:
Many thanks for any ideas.
