This might seem like an obvious question with a clear answer for some.
With the increased availability of higher wattage panels
Looking into adding panels, I’ve come to realize that Team Blue has an advantage as they can choose what they need. However, those of us who are looking for an all-in-one solution like the Sunsynk Deye LUX face a different situation.
I chose these products because I have friends who already have them installed, and they are widely advertised and installed.
When it comes to matching your panels with your inverter, I’ve noticed numerous advertisements showcasing their installations, all of which seem to be functioning well. However, I wonder what might be missing or if I’m overlooking something important.
For the purpose of this discussion, let’s focus solely on the current rather than the MPPT string voltage. As this is easier to see
The Lux SNA5000 has a maximum current of 12.5 A, whereas the Sunsynk/Deye 5Kw has a maximum current of 13 A. To avoid an exhaustive list, I’ve seen various panels being installed with current ratings like 13.5 A, 13.11 A, and 13.8 A.
My concern is: where should we draw the line? Have some people learned from experience, or could we potentially be dealing with ticking time bombs?
A few points to consider: I’m well aware that panels might not always operate at their maximum capacity. Additionally, there’s the ISC (short-circuit current) to take into account.
