Different voltage panels
Hello all, before you answer please read.
Ive done research and I know the putting panels with different voltages together isnt advised. BUT every time I find an exemple, with with really big differences.
I have 5x 48w panels = 3.02A 15.9V rated ( 3.35a 19.8V max)
but 1x 100w panel = 5.9A 17V rated ( 6.5a 21.6V max)
I run a 12v system ( 12v Charge Ctrl ) so i got them all In parallel
Questions;
1 - Its not 18v with 36v OR 12 with 24v ( double the V diff ). We re talking about 1.1V. In my case, Is it as bad as everybody says on the internet ??
2 - The real reason of my post is that I am thinking about buying an other Panel to the lot; 1x 90w 5.17A 17.4V rated ( 5.58a 22.58v max)
--- which would make a 1.5V difference with my 5x 15.9V. I am scared its going to draw down the New 17.4 making it see too many Amps and
wearing it down faster
3 - I feel limited to that one panel because all others are around 18v rated making 2.1v higher, which scares me. Should I worry ?
4 - am I wrong to think that the charge control being PWM so my understanding was that it limited the panels to what was needed thus making okay to
mix my voltage a bit???
Thank you all for your help!!
