Anyone ever use this eco-worthy mounting system? https://www.eco-worthy.com/products/adjustable-multi-piece-solar-panel-mounting-brackets-for-1-4-pieces-of-solar-panels

What are some good place to look for solar panel mounting hardware? I'll be looking to mount panels on my roof that are roughly 68" x 40". Just get some stuff off eBay? Build my own from angle iron at Home Depot?

I guess I am trying to future proof for a planned upgrade to a bigger/better unit in the future. As an example, a Yeti 4000. Not saying I would go with that unit, but it provides an easy conversation with its 13.3-150V, 40Amp, 3000W max on it's HPP charging port (MPPT).

1. I got the "-25*F for the Bay Area" from the calculator. I used this VERY extreme example as the coldest it would get here in the Bay Area and thus the absolute highest voltage I might see from the panels. For example, if I put 0* F as the coldest temp I felt the panels would see, I get a...

As far as going over, I will be connecting my Renogy 450W panels in parallel. The Volts will stay under even at -25* Fahrenheit. The Amps will stay under in parallel (2 panels @ 13.98Amps = 27.89 Amps). So at the coldest temp I accounted for (-25* F) I end up with maximum: 47.33 Volts (-25*...

Thank you!!! I just learned something else (MPPT "pulls" power).

Not being an expert in solar, today I learned about "over paneling" for my particular battery the Yeti 3000X. Short answer: The MPPT controller's HPP input on the Yeti 3000X is rated for 14-50V, 50Amps max, 600W max. If you supply more than 600W but stay under the Volts and Amps maximums...

Thank you. Not being an electrician or knowing some of the in's and out's, that really helps. Bottom line is I need to look at some different panels as the Renogy 2-piece 320W panels are just too much.

Yes, the calcs show the voltage drop is pretty minimal. I think my main concern is that I am looking at panels that are, at maximum/optimum output, just over the WATTS spec of the Goal Zero Yeti3000X HPP Charge port (14-50V, up to 50Amps (600W Max)). Example, if the two (2) Renogy panels in...

The Setup will be two Renogy 320W panels in parallel. I can NOT mount the panels in any other location so the distance is required. Renogy 2-PC 320W Panels ( RNG-320Dx2-US ). 12AWG Output Cables with MC4 connectors. Voc=40.3V, Isc = 10.23 Amps. Renogy 2-to1 Y-branch Connector - MMF+FFM Pair...
