May 30, 20197 yr Morning learned friends, I want to expand my solar array from 6 * 325w panels to 12 * 325w panels, the current setup is as follows: Each panel:Pmax = 325 wattsVoc=45.8vIsc=9.15A 2 * 3 Series combined in parallel:Pmax = 2(3 * 325) watts = 1950 wattsVoc= 137.4vIsc= 18.3A use a 25A fuse I want to add another 6 panels but this time in series to up my Amps and lower my Volts to get from 1950 watts to 3900 watts in total which is still under my inverter specs. Axpert 5kva/4000w rated 80A / 145VDC This is what I am thinking of doing, by lowering the VDC and up the Amps, thus my question is I got a combiner box, and what / how do I need to redesign the box to make it work on the following setup, as I need to take 4 parallel strings and series them all together. 3 Panels combined in parallel:Pmax = 3 * 325 watts = 975 wattsVoc=45.8vIsc=27.45A use a 32A fuse 2 * 3 Parallel combined in series:Pmax = 2(3 * 325) watts = 1950 wattsVoc= 91.6vIsc= 27.45A use a 32A fuse Edited May 30, 20197 yr by Samsed
