Hi all,
I have an off grid system with 8 x 200W panels @ 24V wired as 4 series pairs in parallel.
There are mounted on a north facing roof at an angle of about 20-30 degrees and output November 25 @ 3:50pm was 1200W / 64v (I am in the southern hemisphere)
Ideally I would like to add another 8 panels on the other side of the roof (south facing at similar angle). In our summer this gets almost as much sun and I use the power for irrigation pump and deep freeze.
Inverter / battery charger unit is ISolar SM 3KVA 24VDC Plus
Solar Charger mode:
Rated power 1500W
System voltage 24VDC
Operating voltage range 30/115VDC
Max solar voltage (VOC) 145VDC
My Questions are: Is this doable with the charge control unit I have and what are the implications of having panels facing different directions? Am I right thinking that panels with higher output are reduced to lowest output of any panel in the array?
Thoughts and advice much appreciated.
