You aren't with us anymore but I still have to jump on your answer, as you were so wrong. The 2-pole Square D QO breakers are also UL approved for DC. In this case the highest voltage level these breakers will ever see is 61V and the highest amperage is 20AMP. This is a huge cushion from 240V...

OMG! I had no idea how difficult it would be to get, what I thought was a simple straight forward question, answered in this forum. Several of you have been good in helping me but, now my questions have become five pages of confusing argumentation. If you view this through the mind of someone...

I would really appreciate everyone's comments be addressed to a total off-grid system, if possible. it will cut down this inquirers confusion between comments. I am looking for help in a total off-grid installation of a Sol-Ark12K system with 11,680W of solar panels.

I have done that with my panels and ground mount. What I am trying to do now is ground all my boxes, switches, breaker box, etc., together in case I have a short.

I am totally off-grid.

Will it be OK to make the connection of the 6AWG wire to the other ground rod lug I have in the ground at my ground mount, run it through the combiner box ground lug, disconnect switch ground lug, through the conduit to the emergency shut-off switches ground lug, then to the inverter ground lug...

To begin with, I was not planning to run anything through my conduit but the PV wires from my disconnect switches at the array to the emergency disconnect switches outside my solar shed then to the SolArk12K. Then a brother-in-law of a friend who stopped by decided to spew his wisdom (or lack...

Thanks so much for your clarity and expertise. I finally have a handle on it. Now off to get a 500ft roll of green 6AWG stranded copper wire.

So I just connect it to the ground lug in each box?

Thanks! I apparently didn't clarify my question behind the use of this wire. I never intended it to be used for grounding for lightning, only for connecting the neutral in my switches, combiner box and other items that need connecting along the path of the PV wire. I have yet to see it's purpose...

The two ground rods on my ground mount are only 25' apart tied together with 2 pieces of 6AWG bare stranded copper wire buried a few inches below ground level with a bare stranded copper 6AWG wire attached to one rod and all components, including the panels of my array. I can run the green 6AWG...

From the looks of this, I'm definitely disconnecting the one side of my array from the ground rod on that side and leave the wire between the rods attached. Then run the 6AWG wire from the ground mount to the solar shed through the conduit for neutral bonding of everything in between and get a...

What I have done at the ground mount is put an two 5/8" x 8ft ground rods, spaced one on each side of the ground mount coupled to a 6AWG bare stranded copper wire attached to the stanchion and panels then to the rods on each side. I also ran another wire between each rod and grounded my...

Are you talking about a wire through the conduit from the array to the Sol-Ark or the array to the ground rod? I've already grounded the panels and ground mount to the ground rod.

This is a ground mount. The one thing I don't want to create is a potential for a ground loop. I think that driving another rod would be the fastest way to create one. From what I am hearing, I don't need to run any wire for a neutral or anything else then? I've put in a ground rod for the AC...

I'm installing a Sol-Ark 12K system on my off-grid farm and have a question about grounding and bonding. In many videos I have watched, I have noticed that a green 6AWG THNN stranded copper wire is ran inside the conduit along with the PV wires from the array to the place where the hybrid...

I've done that but, I don't want to create any ground looping with the bonding of my components. Maybe it's best I start a new thread on my question?

This is probably not the correct forum to be asking this question but, because there are many here that have a Sol-Ark 12K system online in an off-grid system, I thought I would throw it out there. I'm currently setting up my Sol-Ark 12K and have a question about grounding. I am running 2 pairs...

I agree with almost everything you just stated. The problem I have had with Sol-Ark is twofold in addition to all of the arguments I had with two of their engineers in May of 2020 regarding the Sol-Ark 12K 63V working with my LTO SCiB batteries. They put a 63V model manual in the box that came...

Shawn, my friends dual Sol-Ark 12K system does the same thing when his wife turns on her hair dryer. There has to be some type of distortion backing through the AC 120V system that creates a problem with the DC conversion rate in the Sol-Ark that is corrected by using an auto transformer. After...

Shawn, after going back and forth between Sol-Ark and the vendor who sent me the 59V Sol-Ark 12K, I was trying to sell earlier, the vendor finally had me return the unit and they sent me a new outdoor Sol-Ark 12k 63V unit for a replacement. But, after David Poz, who like us thought that Sol-Ark...

Where did you see the listing of 6 PV inputs in a Sol-Ark 12k? You can run a +- PV pair of wires, up to 450V@20AMP to each charger (only has two) of the Sol-Ark 12k. You can actually go to 500V but, the Sol-Ark 12k will shave 50V off and 450V is recommended by Sol-Ark.

I don't think anyone but, this guy I met, that installs solar power systems for a living, is missing anything. He was wanting to change the way I helped install a friend of mine's strings in his array that I wired like the strings in my array. I purchased 8 more panels that were 370W monos just...

I concur with you. I'm thinking that he's thinking more about balancing issues in the Sol-Ark 12K. I told him that the same thing would hold true if all of the panels were the same wattage due to the way certain panels would be producing Watts. Thanks for your input!

I need to settle an argument. I have 16 360W panels and 8 370W panels I am wiring to a Sol-Ark 12K. I was going to parallel two strings of 8 of the 360W panels to one charger and string the eight 370W panels to the other charger in my Sol-Ark 12K. A guy, who installs solar told me my Sol-Ark...

Thought I would let those of you, who have graciously lent me advice, in on the current situation with my 59V Sol-Ark 12K. After almost a year of bantering back and forth between Sol-Ark and the alt-E store, who I purchased it from, alt-E has decided to replace the unit. So, it looks like my...

61V The Toshiba LTO SCiB batteries are 64.8V and their sweet spot is between 60V Nominal and 48V Minimal. My BMS are at 59.7V

This is a 59V maximum charge hybrid inverter. So the highest Nominal charge I can get is 58V and my BMS will never top.

I'll sell you one I have that has never been removed from its box for $5995 plus shipping. It's a Sol-Ark 12K 59V

Apparently when Sol-Ark first came out with the 12K it was made with a 59V top end charge maximum rate for a short period before they changed it to the present 63V rate that they have now. I'm assuming that the Alt-E store had some older stock in this configuration that they sent me. This unit...

I purchased this one from Alt-E for $6850 plus shipping

Interesting, because I can't find anything close to this price.

Because it won't charge high enough to get the best curve from my battery bank. My LTO SCIB batteries are 64.8V and I intended to charge them at 61V with a Nominal of 60V and a Minimal of 48V. Therefore, my BMS'S will never make it to top charge. The maximum charge of this inverter is 59V.

A year ago I purchased another Sol-Ark 12k. I opened the box and perused the manual to see if any changes were made. After not finding any, I put it back. The following week, I fell 19ft. off a scissor hoist while hanging a light fixture in my shop, resulting in 14 fractures. 11 surgeries and...

You can set a bulk charge rate at 54.4V or lower down to 51.2V. You amperage should not be set over the 30amp maximum of your battery's limit. Here is why I don't think you times the amount of batteries times the maximum amount of amperage each battery can handle. If one battery is full then...
