UltraSolar

I need to know what mm size my grounding wire should be from my solar array to my earth spike. I need to submit my sseg application but cant seem to find the mm of wire i need to implement.

Yes thanks for the input. I do have a branch connector and will look into the inline fuses.

Thanks for confirming. The 20A is the max fuse rating per panel and not the fuse i intend implementing.

I have been doing some research and need to confirm if my solar panel calculations are correct. I have a SRNE 3kw hybrid inverter HF2430S60-100. The inverter supports the following pv input. 1600w max input. Max open voltage 100v. Max input current 40A. I have 6 x 350w panels with the following specs. VOC (45.1). ISC(9.88). Max fuse rating 20A. With my calculation i have determined i can connect my panels in series parallel 2S3P where two panels are connected in series and three sets of two panels are connected in parallel. According to what i'm calculating my max voltage will be 90.2 and max amps will be 29.64 which both is within the limits of the controller. I need to confirm if i am correct. Your assistance will be appreciated.

Thanks for the tip. I will give it a go.

I see with their new software update the colour schemes are very dark. Is there anyway to change this as i find it difficult to read.

I am new to the forum and just saying hi.
