Yeah, and you can see in my video, taken at night, that my inverter is maxing out at 8973w. Interesting that your temp is also climbing. I was told by sol-ark to update the firmware or tune down the max output. I haven’t tried the firmware, but I can’t imagine that it’ll magically fix the...

Ambient temp is 50-60F. Excuse the old picture (mid-install), things are more buttoned up now.

Ventilation is pretty good. No sure about the fans.

Can someone explain why my sol-ark is beeping at me after about an hour of full 9k battery power. Shouldn’t the inverter be able to handle this? My cables are properly sized. I’m unsure where exactly it’s getting this temperature reading to begin with. Any help is much appreciated.

Hey there, do you still have one of these available? I'm curious as to how it can monitor a 24s pack, since I cannot find a complete 25 pin harness for 24s. My harness that is connected to Daly BMSs is actually split up into two harnesses (one for 17 pins and one for 8 pins I believe), but I...

I was under the impression that the internal bms does not function without an external power source. In Fits, the bms were powered by the starter battery iirc. There’s a bunch of guys at the Honda Insight forum that have done a ton of work in these modules.

I did. It's been running great since this summer. I found the individual cell voltages to be remarkably balanced without the need for bms balancing. The Dalys are hooked up, by I ask nothing of them other than low voltage and high voltage cut-off. That said, I keep my battery bank between 51...

You feed 6-4 wire from your Sol-Ark's Grid breaker into a 60 amp breaker in your main panel and run CT sensor wires to your incoming main lines inside the main panel. This will enable the ability to use the limited to home mode which will zero out your meter prioritizing solar>battery>grid...

Just out of curiosity of seeing this big red notice in the manual, what would happen if the Sol-Ark's loads out breaker would be fed into a main service panel instead of a dedicated sub-panel?

Thanks for your reply. Which Sol-Ark model do you have? I just replaced my 61v model with a 63v outdoor model and there was a new menu option in the advanced tab titled "CT ratio". This parameter was the difference in some really strange behavior with my Sol-Ark and some relatively normal...

I haven't had a chance to go through this entire thread, so am not sure if the answer has been figured out, but I had some CT issues that took me some guess and checking to figure out. So.... I've had the 61v Sol-Ark 12k and recently the 63v outdoor rated 12k. My first model did okay with the...

Just wanted to update that Sol-Ark is doing the right thing. They are replacing the unit that was damaged in shipping with a new outdoor unit. I am unsure whether to define the model they originally sent as a refurbished model. It may be a game of semantics here, but it was an unused model...

I just want to be clear that aside from not charging batteries above 85% I really love the Sol-Ark 12k. I’m using it to zero out my meter and it’s so easy to install and manage all elements of my system. Just wanted to be clear that my issue is how they are advertised and then how issues are...

It’s in my email correspondence.

So last year I bought 40kw of used Lithium Titanate Oxide (LTO) Toshiba Scib modules. I got a great deal on the batteries so was looking for an inverter to pair them with. The voltage range on my batteries are not common, however, so I did a lot of research before buying an inverter. The...

That is correct. It can do 9k to loads and 3k to batteries.

In my setup, I'd be running the main panel and a critical loads panel like in the video and not using a multi-circuit transfer switch like in the manual (and your setup). I just wasn't sure if the wiring was the same on a critical loads panel as on a multi-circuit transfer switch since above...

The above image is from the Sol-Ark manual. It shows a hot red wire going from a breaker in the transfer switch to the breaker in the main panel. However, when watching Gain Solar’s video on wiring a critical loads panel here... It seems that he does not retain a breaker in the main panel to...

So if I'm understanding the Limited to Home mode correctly, the Sol-Ark will use PV (and battery under time of use settings) to power the home panel while using the grid to fill in when needed. This would be ideal for me since I do not want to deal with a grid-sell contract. My question is...

So I wanted to share a little about the 12kw ground mount array I've been putting together. I think it's a winner, as far as costs go, but may not be for everyone in every type of situation. Still, I hope this serves as inspiration for those looking to cut costs and do things on their own...

All went well. Plastic bag, mason string and shop vac worked great for first leg. For the wire pull I definitely needed a helper pushing wire as I pulled. I built my array using galvanized steel 2in square sign posts (the kind with 7/16 perforated holes every inch). This allowed me to install...

Thanks everyone for the tips

Good to know. I've already bought the PV wire so that will have to make do. Do you have any tips for how you fished 6 wires through 1 inch conduit?

I’m hoping to be able to fish 8 10-gauge wires from PV array to Sol-Ark 12k and parallel at its dual mppt controllers instead of paralleling at array and fishing 4 wires. My reasoning is that there will be less energy loss over the 200+ foot run. Just not sure how easy it would be to fish 8...

So my system design is a bit unconventional since I'm building it around 40KW of used LTO modules that came from used EVs. Each of the 36 modules will be paralleled into two separate Square D QO load centers, each with a dedicated 2 pole breaker. I'm using two load centers because each will...

The panels I'm looking at are 32 of of these 400W Jinko brand in 4 strings of 8 panels (12.8KW). https://store.santansolar.com/product/jinko-400w/ The Sol-Ark 12k listed here...

Looking at the Alibaba page for Yangtze, there are multiple listings for 500w panels, but I'm assuming they are all the YS500M-96 model? It looks like you have different panels than the poster who had glue all over his. Could you speak to the build quality of the aluminum frame? And based on...

Hmmm, so even if the screws don't have anything to bite on underneath, the peaks are sufficient to install on. Or would the screws be long enough to bite to the wood below, but not tighten as to created bend the metal down?

Anything to report?

All of the railing I've seen is installed on the peaks of the the metal sheeting and I was wondering if there's railings that are secured in the valleys. The metal roofing on my barn is secured in the valleys where the metal touches the wood below the sheets. I could install on the peak, but...

I think I'll just put the BMS that were sent even though I won't get balance capability with using the Sol-Ark. I'll at least get the overcharge and over discharge protection and will be able to manually monitor the cells like you said you would be doing. Here's the latest I heard from Daly...

Right on. Thanks for the advice. I'm not putting another BMS order in until I'm sure of the specs. In the message you posted above from Daly, I'm curious why you want the charge voltage cut-off at 2.5 instead of something higher like 2.7. Wouldn't having your charge voltage cut-off and...

Interesting. The gal I've been in communication with says that they cannot go above 20mA +/-5mA for charge current. This presents a bit of a problem for my setup as under ideal conditions with 12kw of panels, I would be well above 20mA. Although, I'm not sure ideal conditions would ever be a...

Was wondering if there's a good video or write up on battery safety out there. I'm about to start working with some used cells and am hoping for some good resources. Thanks.

So on the spec sheet of the BMSs that I ordered the over charge is 2.85v and over discharge is at 1.7v. Did you specify with Daly the parameters you'd like for these charge and discharge cut-offs so that they'd match the range you're shooting for (say 48v-60v (2.0v-2.5v per cell)), or is it...
