Cold weather

[Traviss224]

So we are getting a really cold snap. My voc on my panels are 37.6 times 6 panels in series for 226v. (Though I haven't seen more than 205v) My growatt has a max of 250v.

The temp is dropping to around 20 degrees @0700. The calculator factor puts me over to around 255v.

What can I do? Turn my breaker off for my panels after dark tomorrow night? And leave off for a couple days until it warms back up?

Put a tarp over one panel.

I have 6s3p so cover one panel on each series? They're on the roof so it will be a bit of a pain to get to but do able.

Welcome.

Sometimes the simple fix is the best fix for a short term problem.
