Recommendations for panel sizes with 2 x sna5000 + panel technology.


Recommended Posts

Hi guys,

My Lux parallel install was completed last week.

I moved over from a Growatt spf5000es to 2 x lux sna5000.

My current array is 9 x 455w JA mono panels in a single string - the installer connected this to the first lux, there is a setting on those to bridge the 2 Mppt.

My second invertor has no panels connected yet and now i am wanting to add a second array.

The 9 x 455 JA panels have filled up my only North facing roof.

I have a North East Facing roof, and I have a West facing roof.

My plan is to first put a string on the NE roof, and then later add another string to the W facing roof. to utilise invertor 2.

Im stuck trying to decide on recommended panel size and technology.

I have read that Percium is becoming the market standard, and Bi Facial is also worth it.

Lux support recommends 455w sized panels, but seen some nice seraphim 560w bi facials at a good price.

May be inclined to stick with JA.

What would you do?
