Solar Panels for Delta Pro

[Steve-B]

Hi, First time here and a noob so take it easy ?
I have the Ecoflow Delta Pro and was running 4 175w Renogy panels. I just purchased 3 more and made a minor calculation error.
The open circuit voltage for each one is 21.6v x’s 7 would bring total voltage to 151.2v and Max is said to be 150v for the Pro.
Is the additional 1.2v something to lose sleep over or should I just run 6 panels and return one?
I believe alll I can do is run them in series because Max amps is 15 and each panel has 10.35 amps.
I appreciate any and all advice.

I would say send back your charger and get a larger one. I'm a noob also but I personally pushed my Renogy one too its limit about a month ago it failed into 24v mode even though it is a 12 volt system frying my inverter. I partially blame pushing it to the labels max and will oversize my charge controllers from now on.

That is too much. They tell you not to exceed anything after the recommend voltage for a reason. You could do 21.6 x 6, but you have to take into account lower temperatures as well. When the temperature gets lower, it spikes your voltage, so those 6 might be cutting it a little close to voltage max.

You could parallel 3 x 3 and not ever have to worry about voltage at all. But then you'll need some parallel adapters.
