I'm Here, But I'm Not All There
In the past year I purchased 2 of the 4/2 combiner boxes from Watts247. System has been up and running about 5 months.
- Array is an 8s4p 365 watt panels
- Goes into 2 Watts247 Combiners. 4s into 1, 4s into the other
- 2p comes out of each, and Each of these 2 go to the Growatt AIO and SCC. Each has 2 MPPTs
About 6 weeks ago we realized we were only producing about 25% power from the array. We checked the combiners and 3 of the 4 breakers were tripped. 2 in one box, 1 in the other
Why might they have tripped?
Here in Florida, we know a few days before this happened we had violent thunder storms in the area.
It has since happened 2 more times in the past 6 weeks, but again, it has been very stormy as it is that time of year.
I know the Combiners have built in Surge / Lightening suppression. Could high volume electrical storms be causing the breakers in the combiners to trip?
What might be causing the breakers to trip in an otherwise normally functioning Growatt 12k system that has no trouble operating at full capacity
