Lekker man!!!

6 x 200W mono panels connect them:
Series: 3 x panels = 106.5 volts Open circuit, Axpert is 145v so your are good.
Then parallel: 2 strings.
So you have 14.04amps @ 106.5volts = 1495.26watt array.

4 x 12v 205AH US battery = 24v = 410ah bank
At 10% charge rate you need +-41amps - Axpert can go UP to 60amps on solar. 

Sure some of the other guys will add more wisdom here to ensure you are on the right track, that I got it right, but all seems to be spot on! ;)

Well done!

EDIT: I like the 2w standby and 98% efficiency of the MPPT. 90-93% of the inverter, not bad at all.
And the 10ms transfer times, I like.

Hi Again,

So Systems has not been fully installed, in my absence a lot has happened.

So it turns out the Panels that were installed were infact 150W panels as against the 200W earlier discussed so we currently get about 60-66 VOC. I am not haoppy about this obviously and I have been offered 2 Options, 1.

1. Supplier to extra panels to match the 6 already installed to make it 4 strings each specs more like what below

Or Option 2

 

Take back the panels and refund.. (Ideally preferred but way too much hassle)

 

If taking the extra 2 Panels will be fine, I dont mind really as I can put this down as part of the learning Curve.

 

Any advise will be much appreciated.

More panels is more wires and frames BUT as long as the volts are in line, the power is there as you expected, it is ok versus frustrations to get it all started again.

Sell them to me at a good price :-) My array is made of 150W panels.

You opportunist you, pulling such a blatant TTT move! :D

EDIT: If it was 310+ panels ...
