17Amps for each MPPT, though it can handle up to 25A on each MPPT, per the specs.
I'm pretty positive the 480V VOC max is for each MPPT, but I haven't received mine yet so I can't speak from experience yet..
It's 480 volts max for both MPPTs, you can have strings with up to a 480volt max open circuit voltage on each MPPT
If the panel in your shop is a subpanel off your main panel, then the N/G bond is already provided in the main panel and should NOT be bonded anywhere else. Even if your panel is a purely offgrid/load panel that is not connected to your main panel, if you are providing AC input from your main service, then the N/G bond is still being provided by the main panel.
Thanks, Gavin, as I like hearing that, however, 480 volts X 17 Amps = 8,160 Watts, and that’s why I am getting confused, because each MPPT is rated for only 4,000 watts, up to (5,000 watts max)! Is my math wrong?
What does turning on the Combine option do? Lock the MPPT controls together so they don't fight when sharing string, and you get 2x the capacity through the magic of paralleling all the transistors and whatnot?
That's the way I understand it.
Ok thanks for this makes sense. My shop has a meter base with a disconnect and the N/G bond is there. This then feeds into my shop panel where I do not have N/G bond. However grounding and Neural are common between both panels. I see the light. Anyway, that brings up another question. This 6000XP will being moved up the cabin and likely a 18kPv will be going in between the Main panel with disconnect and is G/N bonded and panel supplying shop with power. Through the wall into a wire way then off to the 18kPv, then off to the panel (no N?G bond) through a wire way. In this case does N/G bond need to enabled in the 18kPv? Shop is a 40' by 60' with 200A service. I have a 7.5HP 80 gal compressor, Electric/air tire machine, 240v Hotsie and 240v welder that will be my biggest loads. The 200A pass through will be helpful when running them.
I've been running into this same issue myself tying in (16) 450w panels into two EG4 6000XP inverters in parallel. I chatted with tech support Friday and they had suggested I separate my (16) 450w panels into four quad groups and bring two strings into each inverter. That would bring in roughly 360v @ 20amps into the inverter through two separate legs. It will also allow some flexibility when considering the temperature coefficient at my location which is a LOT (-20F during the winter). And lastly they said to try and keep the groups from having overly shaded portions on the same string because the power drop on one panel will effect the entire string on that series. Hope this helps!
I’m guessing they meant 360v at 10 amps on each of the strings. Of course that would only be when putting out their theoretical max which they never do…
That's still only 2 strings. I thought they wanted 4 strings.
Yeah seems like that would be 8 in series on each string. Not sure what they meant by 4 groups I agree.
I initially thought that you might have made a simple mistake in an earlier post, but this latest post makes it clear that somewhere along the way you have gotten a woefully incorrect understanding of how all this works. I seriously doubt that any panel you’re looking at would “produce roughly 176 volts,” and it appears that you are confusing volts, amps, and watts.
