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.

Guest Posted August 9, 2016 Share Posted August 9, 2016 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. Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted August 10, 2016 Share Posted August 10, 2016 Taking 2 extra 150W is fine. You would end up with two strings of 4 panels. My only concern is that when you expand will the 150W panels be easy to match? superdiy 1 Quote Link to comment Share on other sites More sharing options...

You opportunist you, pulling such a blatant TTT move! EDIT: If it was 310+ panels ... Quote Link to comment Share on other sites More sharing options...
