@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.

I don't have batteries, but pass through continues when I shut the 15K down. The screen shows OFF. When turning it back on it takes a minute or two to come back on.

All of my solar panels are on the same roof plane. So, I don't have your situation, but I can tell you that TIGO always reports higher PV production than reported by my inverter.

Check the Sol-Ark grid parameters. May be too sensitive. Out of the box mine weren't set or were set incorrectly. Sol-Ark updated my software and the values populated to ISO-NE.

Eversource NH $13.81 customer charge. It's the same with or without solar.

I verified the settings on the Sol-Ark screen. Power cycle reset did nothing. Now I noticed that grid frequency is 0 Hz. I can only guess that whatever sensor reads grid frequency has failed. Grid voltage at 0 Hz doesn't make sense.

I'm still waiting for install to be complete, but I'm 100% going with Pytes E-Box 48100R. I'd like to go with their V5, but it's probably not UL9540 with Sol-Ark, at least not yet.

Specifically, doesn't support Gen Peak Shaving. However, there have been discussions of generators being dropped when large loads come on. Some have suggested that there is only a single CT for Gen Input. If that is the case I don't see how Gen power can be measured in order to limit Gen power...

There are restrictions on where you can put batteries in a garage. This diagram is from the IRC concerning vehicle impact protection. Florida probably enforces this.

50% was an arbitrary value for testing my system. Just set it to 10% if that's what you want. This will be SBU. Yes, grid charge off in all time slots.

I'd rather not, but I have for now until I get notifications back.

Now we know that Deye has the unlock code. Many have concluded, implied, suggested that Sol-Ark had the unlock code. No, it was Deye and therefore Deye are guilty of bricking inverters.

Here is the screen on the Sol-Ark.

What? You literally inferred that he was lying or a shill.

Yeah, perform on par with the non-optimized strings.

Moving away from discussing your settings, do you have your solar panels on more than one MPPT input? If so, you should look at the current and voltage and compare string performance. You can select different parameters to graph from the equipment tab. In this example, purple is Ipv1, burgundy...

The manual instructs the installer to add to their account and then transfer to the owner. I disagree with this. I don't see any reason for my installer to have control remotely. On my last system I added the plant before the installer and locked him out.

That's not what @Carlos_Sol-Ark said in this post. He specifically describes TOU while off grid. The Power setting is ignored while off grid, but TOU can be used to select if Gen Charge can be active in any time slot. % in TOU sets the SOC end of charging. If batteries discharge down to Start%...

I think they should reflash the firmware. However, I can't get a response to any support tickets this year. I requested another support ticket last night. I was testing Grid Peak shaving and it doesn't appear to be working. Then the Grid parameter issue resurfaced. Good thing I have Pytes...

Just bringing this back up since it seems like most people missed this.

In TOU, "Charge" is selected to charge from Grid or Generator. It has no bearing on PV charging. When Charge is selected, % is the SOC the battery will charge to.

I checked my settings. Inverter is not functioning as it should. I need it connected so Sol-Ark can troubleshoot it.

Generac 2 wire start instructions.

The one without optimizers does not have panel level monitoring. The results I posted were from the Sol-Ark.

Probably, you can sign up with Sol-Ark for automatic updates. Considering that the unit resets and you lose power for a minute or two, I don't see why anyone would want that.

Back in June 2024 Sol-Ark migrated to US servers and their own version of PowerView called MySolArk. This thread prompted me to open PowerView and found that I could modify my inverters settings from the old App even though it hadn't connected to my inverter in 6 months. I contacted Sol-Ark and...

I'm 74 and just don't have the ambition to deal with it. If you need any help with repair let me know. I bought mine from John Abbott. His son has taken over and has done many other projects for me. He's a licensed plumber, pipe fitter and electrician.

I'm also experiencing arc faults. I have a support ticket with TIGO right now waiting for another event for them to look at.

Nah, because I don't believe it's a true arc fault. For me, the 2 systems faulting at the same time confirms that it is not a wiring fault. Also, it only happens on cloudy days. We have a 3rd Sol-Ark 15K system without optimizers. Zero arc faults there.

You just confirmed what I suspected. Unfortunately, I couldn't wait.

Your right. In an earlier version it was 90 W, then in a later version it was 60 W. In the latest version it's back to 90 W. I can't speak to why it's so high.

Then they shouldn't declare that TIGO optimizers are compatible.

This point doesn't get mentioned enough. If one does a factory reset the Sol-Ark disables Arc Fault detection. No doubt this is the default because Sol-Ark knows they will be inundated with customer complaints if the default is Arc Fault enabled. ☹️

It's a SSR, it only draws 15 ma. My neighbor has the same setup without the TIGO issues I'm experiencing.

I contacted a local solar company to ask about batteries. He threw me a ball park number of $20,000 for a 19.2 KWH HomeGrid. I think his number was pay back for not hiring him to install my Sol-Ark system last year.

You have "Batt First" selected. Change to "Load First".

My primary heat source, home and hot water is propane. I have a 3 zone heat pump system, but it's not cold climate HP and I don't even have enough solar. I use the HP for 3 seasons.

Yup.

Thanks Robby.

Make sure TOU is turned off.

My experience says the diodes work. I have 2 systems on two different buildings. Both roofs are 6/12 pitch. The difference in azimuth of the 2 roofs is about 10 degrees. The system without optimizers is subjected to varying degrees of shading in the morning due to trees. The system with...

My installer arrived with a N/C RSD switch. So, I supplied a SSR and did this. Yes, I know it doesn't do emergency shut down of the inverter, but it passed inspection.

So true. Many including myself have complained that the famed tech support is no more. I suspect they've undergone staff turnover. I'm disappointed with the new MySolArk App. It's just PowerView carried over with features that never worked with Sol-Ark and others that no longer work, like...

I've abandoned my interest in this battery. At 309 lb. I don't know how I'd take delivery or install it.

Think of it as a feed wire and a return wire rather than + and -. All panels must be in series on the feed wire with the final panel connecting the return wire. +ve---Panel1---Panel2---Panel3---Panel4 -ve-----------------------------return wire If you connect the communication cable between...

There's no sensitivity setting. I don't have a scope. As @GregTR said TIGO does not communicate on the PV wires when using a CCA/TAP. The TIGO RSS transmitter uses PLC, but that's a different product.

Maybe this document will explain TOU better.

I installed Pytes V5 in my attached garage. I'm not concerned. The $1199 eBox battery has a charge/discharge rate of 50A. The V5 has a charge/discharge rate of 75A.

I have 2 Sol-Ark 15K systems, one with TIGO optimizers and one with basic TIGO RSD. The system with optimizers gives nuisance arc fault alarms. Arc fault detection is a Sol-Ark function, not TIGO. The system with basic RSD has never given an arc fault alarm.

I have a support ticket opened with TIGO. I'll report back with the results.

My installers were very diligent, went to the big orange store to get shims. They used stainless steel washers. They will order a pair of 4/0 wires because they prefer factory crimped lugs. ☺️ I bought the bus bars that strap the Sol-Ark double battery terminals together. They called PYTES for...

Yes, I think it's an either or situation. You use the TOU to charge the batteries to a specified SOC% (charge checked) or discharge the batteries to SOC% (charge not checked). I think you also have to select "Sell" in order to discharge the batteries. Each time slot can be one or the other. 10%...

I found a setting in the App for notifications. I turned it on, but still not getting Arc Fault notifications. @Carlos_Sol-Ark

What is happening when MLPE are introduced?

I'm also experiencing arc faults with TIGO optimizers. If it's a bright cloudless day, I turn the arc fault on, otherwise I leave it off. I agree that clouds and maybe tree shadows are causing false arc faults. I'm hoping Sol-Ark will experience this problem while developing their optimizer and...

When off grid the SOC values in TOU are the SOC at which charging from generator stops.

The installer sends the documentation to Eversource. Mine went off the rails because the installer used a circuit breaker as a disconnect. Eversource disagreed. Original inspection was late October. Electrician made the change to accommodate Eversource 12/24/22. Before the end of the year...

@Carlos_Sol-Ark has set it to 99% to try that.

What do you have checked here?

My Pytes V5 consume 0.1KWH per day.

I agree with the 7,7,6 array. I'm advising my neighbor with Panasonic 400 watt Evervolt panels and a Sol-Ark 15K. His roof is maxed out, so cannot add another panel.

Thankyou for the pricing. AltE also had a ridiculous price for the V-box-OC early on. I got my V-box-OC from AltE for the same price as NAZ. I'm sure they'll drop the price on the stick. Once my batteries are functional, I'll give them a call. I'm waiting for the 11' 4/0 battery cables to...

Horizontal Iron Ridge rails, landscape panels, except 2 on the right.

True, but who defined what is Tier 1? To me tier 1 is an arbitrary label.

Running mine without battery.

With 1:1 net metering, I can use the grid as the battery. It's more efficient to export and import from the grid than charge and discharge my battery.

It sounds like they are insisting on a revenue grade meter on the output of the inverter. Since current may be flowing to the load terminals, you cannot measure what the PV production is from the grid terminals. I don't know why they are insisting on this. It is required for SRECs, but that...

I wish I had a manual bypass, but I don't. If the 15K fails open, the standby generator will kick in. Not ideal, but better than nothing. Originally, the installer had a 200 A. breaker at the meter and one beside the inverter. The utility rejected the breaker as a disconnect.

I turned off AFCI. The optimizers cause sporadic current waveforms when shadows occur. When I get a cloudless day, I'll turn it on to check for wire faults.

Yes, Sol-Ark shuts off PV production until reset. I can reset through MySolArk App, but since this new App was introduced last June, I don't get a notification and I'm not aware that I've lost production. So, I operate with arc fault turned off.

I was attempting to resolve some other issue and did a factory reset. I am now able to leave TOU OFF, no more PV dropout. :unsure:

The fact that you have significant daily battery KWH charge, but insignificant battery discharge indicates a defective battery. It suggest a battery self discharging. The Sol-Ark wouldn't see that. I couldn't find your exact solar panel, but it looks like VOC is ~ 50V. I have 5 Panasonic panels...

Thanks @robby

I have the same model, installed in 2010. The electronic controller failed in the first month. BioheatUSA replaced the controller with the analog controller. Firewood is no longer economically advantageous unless you have your own supply of trees. I only use it when temps get below 10F. I also...

If ferrites work, then a real fault may be ignored. I'm hoping that Sol-Ark finds a solution, maybe a different algorithm. Sol-Ark has to resolve this before they release their own optimizers. However, they may find the solution in the optimizer rather than the arc fault algorithm.

Thanks @robby Sol-Ark tech support asked if line voltage had risen to 126 VAC. This was in regard to PV dropout issues. Since adding batteries, the problem appears to be gone. I don't know what is significant about 126 volts. It should be able to go to 264 volts L-L without disconnecting.

And it's going to bleed the black ink cartridge if I print any image.

I experienced an F47 fault after a power failure. The Sol-Ark disconnected from the grid and did not reconnect. A call to Sol-Ark resulted in a firmware update and the fault never reoccurred. This was shortly after turning on PV when first installed. It's been 5 months now without a fault.

Fully charged in closed loop my V5 batteries sit at 56.7V.

I have a Sol-Ark which is essentially a Deye, but with some different screens. On a Sol-Ark there is a Time of Use Setup that brings up days of the week that you want TOU to function. The days also have to be selected.

M7222/S1725/C143E from PVPro. F48 fault and multiple F22 faults. I submitted a support ticket. Tech support logged in and could see grid low frequency.

Global charge setting must be selected with or without TOU. With TOU selected, batteries will charge up to % setting for the time slot with charge selected. TOU not selected: batteries will start charging from grid when batteries are less than % global setting. With TOU selected: batteries...

Hang in there Robby. The Jackals are out to get you. They offer no evidence that Sol-Ark did anything.

I know. I was pointing out what will happen to people that aren't aware of the demand charge or don't understand it. I already put off laundry for a day when solar power will be drying my clothes.

Has anyone been to their brick and mortar store? It's only a 1 1/2 hour drive for me. I'm going pick up batteries and save the shipping cost.

What don't you like about outdoor wood furnaces? My neighbor and I had an indoor model installed in the new garage we built. We burned our own wood for 4 or more years. We're not up for the physical labor anymore and purchased firewood is expensive. We fired it a few times last winter when...

I had the V5 installed in April for $1,750 per battery. Back then the eBox was the same price and still is at the AltE store. Good to see the eBox priced appropriately somewhere.

On the system without optimizers I can't monitor individual panels. TIGO has monitor only modules without optimization. Those should work fine with an arc fault detector.

I'm definitely interested in 2 of these for my Sol-Ark 15K. Until now, I was considering HomeGrid.

The V-Box-OC will work for me in my garage. I want a slim profile. However, it's currently not in stock.

That's why I said "infer" not state. By including this on their web site, they are inferring that Sol-Ark data is on US servers.

TIGO makes 3 different TS4 MLPE that work with the CCA and TAP Optimization + Monitoring + RSD Monitoring + RSD Monitoring only I'm sure you can mix and match.

I left my whole house system on for 3 weeks. While I was gone, the inverter decided to disconnect from the grid. My house has been running on solar + battery for 2 weeks. You can read about it here.

Yup. The contract I signed for my last install stated they would transfer the manufacturer's warranty to me when install was complete. People are mislead about installer warranty. They only warranty their workmanship, not the product. Yes, they will take care of product issues during...
