Oh I, I just Dyed in your arms tonight It must have been something you said

Also be aware of where the batteries can be located in a garage.

I had four Pytes V5 batteries installed in the V-Box-OC in my garage. :)

This post was about Sol-Ark failures. Can we get back to the original question?

Not according to the data sheet.

2018. The following text can be found in the lawsuit against Lion Energy. Plaintiff also asserts that, in or about 2018, it entered into a Non-Compete Agreement with NingBo Deye Inverter Technology Co. Ltd. (“Deye”), and that, pursuant thereto, Plaintiff had exclusive rights in the United...

My clothes dryer alone would give me an undesirable bill with this demand charge. It consumes 5KW continuously for about 1 hour. There's going to be rage against city hall with the first bill.

Twice, since Sol-Ark migrated to US servers, one my inverters disconnected from the grid because somebody messed with my grid settings. Yesterday I found out that my inverter is connected to both the US and China servers. I monitor 3 Sol-Ark 15K on this property. The one with the messed up grid...

Sol-Ark didn't cause this. Sorry that this happened to you. Your "so called" dealer is just a reseller in China, not a dealer. He is at fault.

You can't comply with UL1741 and function like a typical UPS. There are ride through requirements. In New England the inverter must stay connected for 2 seconds when less than 88% of line voltage and greater than 65%. The inverter is going to follow the line voltage down to 156 volts for 2 seconds.

Got this notice in PowerView today.

Yeah, the relay folks are faking their ability. As an electronics engineer in the 70's and 80's developing products with a lot of relays, I've never seen a relay this small that could switch 200 amp. At best, this relay can switch 50A.

The reason why this argument goes on and on is because Sol-Ark cut a deal with Deye for exclusivity in the USA, cutting off a cheaper solution for the DIY community. I don't know who developed the technology, but why does it matter. Enjoy your new EG4 like I enjoy my new Sol-Ark 15K.

I did click the save box and got the "sent successfully" "inverter offline" message. Edit; Settings change worked on 2 other plants that I monitor. There are many things in the App that aren't working on my particular unit including incorrect status. It's actually online, but says it's offline...

I've only removed pulled my dongle for a few minutes and that was within the last 2 months. That was on 1 of 3 systems. I requested a support ticket. Update: Tech support removed my systems from PowerView. There is something incomplete about the migration. On another matter, while...

I've been through both New England ice storms of the last 26 years for a total power outage duration exceeding 15 days. I now have a standby generator, but it consumes propane faster than they will deliver it. I keep hearing how weak the electrical grid is. That's my motivation, but it's nice...

I had a few issues including 200 watt idle current on a single 15K. I did a factory reset and all problems vanished.

I found the problem. The new MySolArk app screwed up all the grid parameters, both voltage and frequency. Example LV3 was 300 volts. :rolleyes: Note, this occurred 06/23, well after the transfer from PowerView started. Now I need to dial in the proper times on the Sol-Ark screen. Just like...

No, why should I be? My neighbor just spent more than me by buying 2 inverters. I'd probably be happy that my neighbor is no longer gloating about how much cheaper his Deye was than my Sol-Ark.

My first system generated a credit in April and May. The second system was a $6 bill in May. The flat rate charge is $16, so it covered all KWH charges.

My Pytes V5 batteries are in an attached garage. Lowest battery temperature so far is 8C, hasn't triggered the battery heaters yet. Heater should turn on at 5C. Before anyone comments, the garage door is not open.

Did the POCO use new math to create this confusion? 🥴

TIGO optimizers don't communicate on the PV wires. The CCA communicates over RS485 to the TAP and the TAP communicates wireless to the optimizers.

The V box OC cabinet includes 4 ganged breakers for 4 batteries. It also includes bus bars.

Solarboi posted a response from Deye.

Even on this forum, some people don't seem to know the difference between KW and KWH. Most do know, but then they post incorrectly.

Batteries on a Sol-Ark are a fraction of the cost of batteries with Enphase.

I finally saw with my own eyes; the CCA green LED was off and the TIGO monitoring showed no data for a 5 minute duration at that time. Someone on Reddit said they had my issue, only worse, and it was a bad TIGO power supply. I have another power supply, but I'll wait for input from my installer...

I'm not prepping for an EMP event or any other event that may take the grid down for 6 months or more. I'm prepping for the next ice storm. I've already been through 2, each resulting in lost power for more than a week. We installed a standby generator after the last one. However, we'd be lucky...

I tried the same test as @Cmiller I was able to change Max Solar Power from PowerView. The change immediately showed up in MySolArk. Perhaps your system has fully migrated. I suspect most have not.

2 weeks ago I went back to monitoring my system using TIGO. I hadn't looked at it for quite some time. Data was grossly inaccurate showing daily generation in excess of anything that is possible. I submitted a new support ticket to TIGO. After a few days, they asked me to eliminate the 12 volt...

Thank you for your input. I think you are being overly conservative. This generator has powered 3 mini-split heat pumps (total 70,000 BTU), plus home loads for 2 homes without fail. I'm interested in the ability of the Sol-Ark to stay locked on to the varying frequency.

Yes, you need to check "charge" for all time slots that you would require Gen charge. Your Start % at 10% is really low. This number needs to be higher than your Discharge Shutdown %.

That happened to me last year. I had a single day of grossly wrong export (2,150KWH). I submitted a support ticket, but crickets.

Out of the box Generac air cooled generators aren't wired for 2 wire start. See attachment for wire modification and programming.

I have them on a new Sol-Ark installation. Today was a good sun day, but this time of the year I have a lot of tree shading. The TIGO monitoring reports total production and reclaimed energy. Today production was 14.81 KWH with 3.97 KWH of that being reclaimed energy. I'm not saying this is...

I was initially investigating potential arc fault issues, but now the focus is the TIGO optimizers dropping out for 5 minute durations. The optimizers don't use PLC. The CCA communicates with the TAP on the roof over RS485. The TAP communicates with the optimizers wirelessly. I am using the...

Do not check grid sell.

I found the problem. The new MySolArk app screwed up all the grid parameters, both voltage and frequency.

I'm trying to connect the dots. NeoVolta Selected as Strategic Partner with Barrio Eléctrico for Growth in Puerto Rico as part of $21M Award Neovolta secures 5 year agreement with inverter manufacturer NeoVolta, Inc. v. Portable Solar, LLC What's the connection? Why did Neovolta sue Sol-Ark? I...

I was frustrated that Gen Peak Shaving is no longer supported, but then realized what I was planning to do probably isn't practical, that is charge batteries on 3 separate Sol-Arks at the same time. Instead I'll just use TOU to stagger charging of each battery bank. Gen Peak Shaving would be a...

The Sol-Ark is UL listed, meaning it's been critically tested to carry and switch 200 Amp. You can have faith in the 200 Amp rating.

I had my grid settings magically change on their own. It caused the inverter to disconnect from the grid. This is much worse than just getting bad data. @Carlos_Sol-Ark

What did I say that sounds like whining?

Check with your fire department. Rapid shut down is for their benefit.

ETL is a certified testing lab that tests to UL standards. If it's a legitimate ETL mark, it's just as valid as UL.

For good reason. One person reported that 3 phase Deye inverters that he bought from GreensunSolar were bricked. That web site has Deye split phase inverters for sale described as "For US Home Power Use". Sol-Ark wants Deye to stop selling product specifically intended for the US market to these...

Here's one made in USA.

FWIW default disconnect setting for high voltage on my Sol-Ark 15K is 264 volts.

I'm on grid so that's not going to work for me. I want to charge from my generator, but not from the grid. This sounds like a bug. What firmware are you on? For the 15K current version is M7.2.2.2

When the inverter and battery are UL9540 listed together and the installation instructions show spacing less than 3' then it's a permitted exception.

My first interest is the higher 100 A discharge. Four E box batteries only gives me 10 KW. I want to utilize the full 12 KW capability of the Sol-Ark. The heater is just insurance for me. The batteries will be in an attached garage with the only external wall being the garage door wall. I don't...

I've been through the ice storm of 98 and 2009. I added 20KWH of battery to my solar system in anticipation of the next one. I have a 17KW standby generator, but fuel on hand may only last 2 to 5 days. Likely would be a week before I could get a propane delivery. The last 2 ice storms were...

I don't plan to open the switch with current flowing. Even Sol-Ark warns not to open the built in battery breaker with current flowing.

No, I need UL9540 for AHJ. My power demands will be higher in the summer with A/C. For a winter power outage I turn off the heat pump and run my propane fired hydronic system. I have a combi-boiler.

FWIW, this is BMS SOC, voltage and current for my Pytes V5 batteries. Charging source was PV.

If he flips the wires after running auto CT detect, he would need to run auto CT detect again.

Everything you need to know should be here.

I imagine the V box has an internal fuse. I know the eBox has one. Also, current limiting and shut down with FET BMS. eBox has a 100A current limit that shuts down after XX seconds. I don't remember, maybe 5 seconds.

3 weeks into 2025 I've generated diddly squat. Snowed last weekend then super cold, so panels remain snow covered. Green is PV.

Not yet. When Sol-Ark releases their optimizer, they will update the MPPT board to include SunSpec PLC.

Why assume that Sol-Ark initiated this? There's no threat of Deye units being deployed in the USA anymore. There's a higher probability of that happening in the UK or Pakistan as they don't have split phase power. Split phase is not common outside of North America.

Clear skies in NH.

Most jurisdictions in the US require panel level RSD (rapid shutdown). Without shading issues it might be better to use RSD modules that don't optimize, as there's no power conversion going on.

Here is a data sheet from OMRON, a company that innovates, not copy like a Chinese company. This is a data sheet that I believe. 50A make and break rating.

A picture is worth a thousand words.

Is your dealer in Costa Rica? Did your dealer buy directly from Deye or from a distributor in China?

NFPA® 855 Standard for the Installation of Stationary Energy Storage Systems 2020 Edition 15.7 Energy Ratings. Individual ESS units shall have a maximum stored energy of 20 kWh. 15.7.1 The aggregate rating amount within a dwelling, garage, or accessory structure shall not exceed the following...

Deja vu. We saw this 3 years ago when USA buyers could no longer buy Deye because Sol-Ark took action against Lion Energy. Oh the outrage and here we are again. But it's even more wrong today since there are other options today like EG4. Oh wait, EG4 is 2X Deye and no one accuses EG4 of being...

Every one of those BBB complaints have no merit. One was complaining that his utility had an issue because he was back feeding the grid when he wasn't authorized to do so. We all know there isn't a grid tied inverter that can guarantee zero export. They all leak unless the use double conversion.

The 3' rule comes from NFPA 855. 2020 was the first edition. No more than 20 KWH storage in one location with 3' separation to an additional battery.

The installer is ordering the (custom) cables, so I don't know where they are getting them. When I was considering doing this battery install myself, I was planning to buy cables from Windy Nation.

I definitely have shading issues (trees). With 2 systems, one has morning shading and the other has afternoon shading. The one with morning shade is the better performer because PV panels run from ridge to eaves and the snow slides off quite readily. The installer for the second roof followed...

I think you uncovered the reason. However, they should allow you to connect your AIO as intended and take the 6 cent hit.

The AC disconnect is a utility company requirement. I agree that it's unnecessary. The fire department wants the RSD switch.

The relay is capable of switching 50A, not 200A. If you want to believe a BS Chinese data sheet, then we should agree to disagree.

I have my eye on the new EG4 PowerPro. I'll definitely consider CC.

I called my insurance company to inform them that I now have solar PV on my roof. They had 3 questions; Was the system professionally installed? How many KW is it to which I asked AC or DC? She was totally baffled. :LOL: How much did the system cost? Then there was a discussion about what the...

The picture on page 1 is not being disputed. That's a picture of a Deye inverter screen. Somewhere in the 70 pages someone posted what appeared to be a Sol-Ark screen with the message of death. That's been proven to be fake.

I've experienced multiple arc faults on two new Sol-Ark 15K installations operating without grid sell and no battery. I got PTO yesterday, activated grid sell and hope these faults stop occurring. One 15K was 7.2.2.2 software. Sol-Ark updated the second one yesterday. Both systems have TIGO...

It limits the power from the AC source and calls upon the battery to assist powering the loads.

Trees. :mad: 70' trees blocking my solar production for 4 months. I'm down to 1/3 production on the best day.

I had a glitch, but not a failure. First week after PTO, Sol-Ark 15K (without a battery) would not return to bypass after a power failure. I was able to get it back by power cycling. Sol-Ark did a software update and it hasn't happened since. Prior to this, I had noticed the voltage and...

It's not UL9540 with Sol-Ark.

I have a Mitsubishi Hyper-Heat mounted on a 5 foot wall. It works fine. I requested a floor unit, but it was out of stock and expensive.

I encourage all Sol-Ark owners to ensure they are no longer connected to the China server. Yes, Sol-Ark ported all systems to the US server, but in my case they neglected to remove mine from the China server. I had tech support correct this. All 3 systems I maintain were still on the China server.

Just to be clear, at no time was I powering the CCA with the Sol-Ark 12 volt. I was powering the SSR with the 12 volt. Input current for the SSR is 15 ma, well within the 100 ma capability of the Sol-Ark. Output rating for the SSR is 2A, well within the CCA current requirement. This setup is...

I just had an arc fault and for the second time I see no TIGO data 5 minutes prior to the arc fault event. I have the premium monitoring package that provides one minute resolution. Makes me think the optimizers are misbehaving during this 5 minute blackout. I submitted a support ticket to TIGO...

I grew up in small town (population 20,000) Ontario Canada. I moved to the US when I was 46 to preserve my job. I've lived in ME, FL and now NH.

Do you have Zero Export Power set to 1000W? This setting may have a different description on a Deye, Typical value is 10W or 20W. It's a value to prevent grid sell.

@cs1234 Where did you see that Sol-Ark sued Deye? I know they sued Lion Energy.

I doubt that DEYE maintains a UL listing on a product they aren't allowed to market in the US.

That's just a typo. The 15k is 7222 or something that starts with 7, I forget.

According to Sol-Ark 15K manual, Gen Limit is only for generator connected to Gen terminals. Gen Limit Power: Sets the Sol-Ark limit to keep the power drawn from the “GEN” terminal below the threshold. The inverter will reduce the charge power rate to the batteries if this value is reached...

SOK Certifications: UL1973 & UL9540A certified, UL9540 pending

Found this in the PowerView document. The PV settings document explains things so much better than the Sol-Ark manuals.
