This is a link that shows how much shading killed production with my panels...

Morningstar makes SOLID gear. Several of us can/have shared about thier support after the sale. They didn't even flinch at sending me...

Ah, I didn't explain well, there were just two options there, the 2S8P in two rows or 2S8P in two 'squares'. Then the other two pictures...

In your case the best you have is top left and top middle. The more parallel sets you can get, the better the results. This could also...

I'm looking for a new charge controller that can handle max VOC > 470V. So far I've found these two models, but they have a very...

Thanks, that sounds good.

I don't believe you need to derate if using fully rated breakers like the Midnite mnepv series. I would go with two mnepv20 breakers in...

For the breakers in a combiner box then I'd want to multiply by 1.25 right? So the 12.68 x 1.25 = 15.85A. That could maybe work with 15A...

I multiply VOC 41.51A by Isc 12.88A and get 535W. Two parallel strings you'd be looking at around 26A. Some bifacial spec sheets I've...

Instead of "amps leaving" i think you should say,"amps that can be supplied" Im not an electrician, but volts are all that matters...

I have 16 panels that I can arrange on a single large array. There are several tree shadows that are present in the Winter during the...

I am trying to calculate the max amps for breakers and for wire guage estimates, but I realized the way I was calculating it for...

Curious to know who is using either the software for the computer and or the app (for cell) to monitor their EG4 inverters. I'd like to...

That should be easy enough to string more wire.

https://www.morningstarcorp.com/products/tristar-mppt-600v/ close to $900. Shop around. Probably half price or less from China.

I don't know why you want to run higher amperage instead of higher voltage. I'd look for a charge controller that is higher than 250VOC...

The wires are buried in a large maybe 3" flexible PVC, like the ones used for water irrigation, the parts above ground are in electrical...

Oh got it, sticking with 4S strings. The good thing about voltage drop is it's only that bad at full output, which is when the solar is...

Just keeping their existing Midnite Classic 250. It's pretty beat up at this point, hums like crazy and the screen craps out all the...

Thanks, You were correct that 8 in series VOC would go over the max VOC for Midnite Classic 250. Likely will stick with the inefficient...
