So each MMPT is separate, but you still can not go over the maximum total voltage max of 550 for the operating voltage total for the inverter? I was looking at the mission solar panel MSE425-SX6W (MSE PERC 72 415-425W) and based on my temperatures of -5, the lowest ever recorded, although...

Thanks JWLV -- I understand, but would that not hurt efficiency. It seems like you would be spending lots of dollars on equipment that is not working for you or is this just the way it is. To get to 11KW it is going to take fair number of panels. 11KW is my net zero number. Also if I...

I am in the beginning stages of a Solar Build. As I research and learn about setting, the inverters have limits. Typical is a 600V input and a max amp input of 16–18. All this is dependent on inverters, but those seem to be common. It looks like I will need 20 panels. Again, depending on...

When i get everything together I will post the build under another thread but wanted to ask some questions separately so it is easily searchable.

Thanks. I have been researching a ton on here and also using "The Google" That is kind of what I figured. I just hate to spend dollars that are not working to their maximum capacity. I am planning a Grid Tie. Texas has good net metering and even the ability to sell back but I just mainly...

I was tracking your comment #2 -- "2 strings of 9 panels at 540w each going to an inverter. " the OP is putting in a smaller system but for someone looking for a Grid Tie like his friend with 20 480w panels, how would this work? Those 20 panels will either exceed the maximum DC input in...

Sorry, I tried to get the data sheet in with the post, but it did not work. I am in the same boat as the OPs friend. looking at a 11.4KW system -- approx 20 panels and pushing it a long distance approx 400-450 feet. I want to stay at a high voltage to run the distance for wire cost, but the...

Got it. that was what I was looking for. I found something similar in a YouTube video, but it was nice to hear it again from a different source. I know Growatt or a DIY solar help store could have answered just not ready with all my questions to call them just yet.
