stoic Posted December 10, 2018 Share Posted December 10, 2018 (edited) Can anyone comment on my array configuration? I have 2 unused panels that does not fit into this configuration, any idea how i can make it work better? Any suggestions?

Arandoza Posted December 10, 2018 Share Posted December 10, 2018 Hello Soic, I think you forgot to add your volts together per array, 76v x 4 = 304v per array (8 panels)? You added the watts and also the amps together but not the volts. if you combine the 3 arrays in series it will give you 912v if you connect them in parallel it will remain 302v if not mistaken.

Gabriel_2018 Posted December 10, 2018 Share Posted December 10, 2018 If two panels are 72 cel you can add two in the series you want Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted December 10, 2018 Share Posted December 10, 2018 One cannot really comment unless one knows what SCC you will be using. basically you have 12 strings consisting of 2 panels in series. You either going to need lots of inline fuses or you going to need a massive combiner box. 2 panels in series is likely only going to suit an Axpert or a smaller Victon or the like. I would like to see 8 panels in series if possible. Quote Link to comment Share on other sites More sharing options...
stoic Posted December 11, 2018 Author Share Posted December 11, 2018 (edited) Panels are 72 cell panels. @Chris Hobson I have three inverters the synerji ones SYSH18-5K Plus in specs below The panels on my will be on my roof... no shade for any of them. My assumption is that i need to supply each inverter independently. Looking at the spec below i figured i need to supply between 64V and 140V DC and i am also maxed at 60 amps / 3000W. The configuration i drew up using paint falls in that range. My battery bank is also a 48V battery bank so i am just over that as well.

Look... this is Grade 8 Physics, so i can be wrong, i was in grade 8 24 years ago, but i think i did it right Quote Link to comment Share on other sites More sharing options...

When you parallel , you need to add the amps of each string together, but the volts will remain the same. Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted December 11, 2018 Share Posted December 11, 2018 In series you add volts in parallel you add amps. The figures in your diagram are correct. If you using Synerji inverters then 2 panels is probably your max. I see that each array is for one inverter. Quote Link to comment Share on other sites More sharing options...
