Fwiw, THHN is tested, during production, at way over 1000 vdc. So 600 vdc, no big deal.
Agreed, but can see the flexibility having over 450V that I believe Victron maxes out at?I see little reason to need more than 600v, even for a long run PV Array. 600v is downright terrifying lol.
There's a soft limit of eight times the float voltage of the battery, so around 432V with a float of 54V.Agreed, but can see the flexibility having over 450V that I believe Victron maxes out at?

So looks like NEC 2020 limits to 600V on or in a one or two family dwelling, commercials good up to 1000V but if you have a powerhouse/accessory structure for the equipment and ground mounts looks like we are good to 1500V with "listed" equipment? Now the question is with the higher voltage I think there is a minimum spacing requirement such that the worker can be thrown back from the equipment and be clear of contact? Anyone know what that distance is? Would be handy to have that free space when designing a powerhouse.Missy of the Fronius Primos are rated to 1,000V and there have been a number of times that we actually stringed higher than 600V because it just worked out better.
Just like battery voltage of 12-24-48V, as you go higher on PV voltage, you see uses for even higher voltage. Yes, I know the higher the voltage, the more dangerous it gets. But man it's handy running a string of 12 (or 14) 450 or 550w panels..... now if you can run 2P on your PV, you just double up. But for AIOs or other mppts with only 16A input you can run into limitations!
One job where we went with higher voltage recently was a ground mount with the Fronius mounted on the array. Service drop was on a pole, then the house was 300' away. Solar array was right next to the service drop. No local inspections for residential. PV wire literally went directly into the Fronius, so everything just kind of fell in place to run a higher voltage string.So looks like NEC 2020 limits to 600V on or in a one or two family dwelling, commercials good up to 1000V but if you have a powerhouse/accessory structure for the equipment and ground mounts looks like we are good to 1500V with "listed" equipment?
This would be interesting to know! Although, I guess I'm not aware of an inverter that is rated to 1000V and can't be installed outdoors... So maybe the answer would be to have it mounted on the outside wall (exterior) of a powerhouse and have any other equipment (such as batteries etc.) inside.Now the question is with the higher voltage I think there is a minimum spacing requirement such that the worker can be thrown back from the equipment and be clear of contact?

hehehhe...my first in-progress video is demonstrating the serviceability. Essentially I am taking it down to a sheet metal case with nothing in it, guts spread across two workbenches, then putting it back together and installing it.Still waiting for someone to open the top of that so we can see what it looks like, especially since it is supposed to be user-serviceable. Also just looks a lot smaller then a 18kPV.
Will the video be available this year, by any chance?hehehhe...my first in-progress video is demonstrating the serviceability. Essentially I am taking it down to a sheet metal case with nothing in it, guts spread across two workbenches, then putting it back together and installing it.

I don’t think anything is totally restricted, but I always like to check with MN because I don’t want to give information that may change.Is there any current restrictions on what can be talked about/revealed until a certain date? The few vids available doesn't actually really reveal anything that you couldn't get by reading the specs.. although last video did mention being able to run loads with ONLY PV power available which was interesting.
Impressive but they need to include duration on the front page/sales flyer. Are we talking seconds or a fraction of a second? It makes a big difference. Wish they would say up front.13kw surge on single leg is way beyond what the sol-ark can do if I'm not mistaken?
Seems unnecessary for something that once its running, you would rarely look at. I don't think the screen on my SolArk has turned on in weeks lol.Some day they will put a normal size screen on these units for us old people to use.
If the display can be duplicated via web browser or app can run it on a big tablet, in the convenience of your favorite recliner.Seems unnecessary for something that once its running, you would rarely look at. I don't think the screen on my SolArk has turned on in weeks lol.
Right in the specs sheet:Impressive but they need to include duration on the front page/sales flyer. Are we talking seconds or a fraction of a second? It makes a big difference. Wish they would say up front.
Peak Output Apparent Power(1s) | 20,000VA (13,000VA Per Leg) |
Doesn't seem like long but thats a huge difference versus the solarks and eg4s with zero surge capability on the 120V legs. Basically need to buy two solarks or eg4s to get close to matching that.Right in the specs sheet:
Peak Output Apparent Power(1s) 20,000VA (13,000VA Per Leg)
I imagine it's not quite as long as the blue, green, or yellow LF inverters, but it sounds like it's very respectable for an HF inverter.Doesn't seem like long but thats a huge difference versus the solarks and eg4s with zero surge capability on the 120V legs.
