"our revolutionary hybrid inverter design" - irony is rich over there in TX

FYI, this is how you tell the difference between battery versions

Regarding UL listings - UL 1973 is not sufficient for residential battery installation if your state is on the 2018 IRC. Section R327.2 of the 2018 IRC states that energy storage systems (ESS) be Listed (Certified) to UL 9540, meaning the combined battery and inverter (ESS) have undergone fire...

The court didn't agree on the facts of that lawsuit. The case was settled by both parties out of court and dismissed. Can you shed any light on the Lion Energy product now being sold (again)? I think you raise some fair points about the difficulty and reality of global manufacturing...

I answered my own question on this. I requested additional documentation from Pytes for their UL9540, see attached which shows it was approved with the Sol-Ark 15k, as for as I can tell this should be approved to install in 2018 IRC jurisdictions

Hi, I wanted to get the forum's thoughts on this battery. It seems to be one of the first 'cheap' LFP server rack batteries that have a UL9540 listing (meaning, I believe, can be installed and permitted in jurisdictions following the 2018 IRC (section r327). Questions: Pytes claims that...

FYI, I am now on 5.2.1.4 as of 5/5/22

I'm wondering if there are other optimsers on the market that would be compatible with a Sol-Ark as I am frustrated with my Tigo TS4-A-O's. Main complaints: - Their cloud service is not reliable and only has 15 minute resolution without paying extra (and is closed source, can't locally...

Here is the info, direct from Tigo. Neither the -O (optimizer) which requires the TAP and CCA nor the -F which just does rapid shutdown which uses the RSS PLC transmitter can draw power directly from the Sol-Ark, they both require external power supplies...

Let's keep this thread clean related to firmware versions. Any questions about features or troubleshooting should be on a new thread. Thanks.

@Keith Gough Keith I think most of the ire on this forum has been directed towards solark who has seemingly tried to disavow their affiliation with Deye, you on the other hand have been quite open about it.

So what did those batteries cost landed in the US? And who is the manufacturer

8 in parallel max. You need a HUB

With all due respect to everyone who wants to rehash this argument over and over between Deye and Sol-Ark and who developed what. I think we should take it from the horses mouth here: https://diysolarforum.com/threads/sunsynk-max-16-kw.35458/post-498891 As @Keith Gough states: "Not quite...

They are never going to balance with that kind of SOC deviation. You need to charge each one individually to 100% to get back in balance. They should be pulling pretty even current under load. Use a clamp meter to see what kind of current is being pulled from each. The best practice is...

Yes, grounding all equipment is a good idea. Mine seem to be pulling current pretty evenly. What software/hardware are you using to graph that data?

I was having closed loop communications problems with my inverter. After checking the firmware version on each of my 4 batteries, one was on a different version. I had to upgrade all 4 to get them all on the same version for the comms to work properly.

@Lt.Dan yes I've definitely searched. I just find it hard to believe that there's no other optimizer solutions on the market. @zanydroid I'm less concerned about the local monitoring aspect and also about the 15 minute resolution than I am with the fact that the optimizers rely on a wireless...

I'm actually exploring getting into the solar install game, because I love this stuff and after interviewing companies in my area (and deciding to DIY), they are almost universally not well versed in the tech or the pricing is just super bloated. So yes, I'm also looking at the Tigos from...

Depends on your specific load, should be similar to other HF inverters. Spec sheet attached shows max output at 8800 watts, if you you have 240v loads should be able to pull max 4400 balanced on each phase. I haven't tested it to see where it actually trips.

You might want to also look at getting a second hphwh and running it in parallel with the first, that should enable you to stay on heap pump only mode indefinitely.

Got it - so Sunsynk is more like a white labeller from your explanation from #45

Here is my setup. I am running an 8k Deye. I have two of them but am only using one right now. The battery box is from Midnight solar. Each battery runs with the Pytes 4 AWG long cables to its own 100 AMP DC breaker from Midnite, those then run to a bus bar and from bus bar to 250 AMP DC...

@robby I think you're spot on with a longevity of electric car batteries, especially lithium iron phosphate which is where everything seems to be headed. Let's also not discount second life uses of car batteries, which a lot of this forum is dedicated towards. More importantly, I think your...

I need them for RSD and I like the monitoring. The delta between the optimiser version and the RSD only version was pretty small so I went for it. You may be correct, but I'm assuming that they aren't making things WORSE. I hope I am not wrong.

I don't think this is correct that SunSynk is owned by Deye - where have you seen this information? I don't think @Keith Gough has been around here in a while, but perhaps he can weigh in? Also, @Keith Gough if you are on here - is @jrcromer description of SunSynk a fair one? That is...

@Ryushin - Looks like you have a 'comma' instead of a decimal. For example, instead of 3.220 kW in array 1 you have 3,220 kW... a big difference that is throwing your numbers off.

Found this: Blind Deployment is defined as any arrangement of TS4 MLPE units being used WITHOUT monitoring enabled (.i.e., no communication via CCA or TAP): Albeit, this type of deployment can function for an undetermined amount of time, it offers no visibility into optimization...

Hi All, I can't really find a thread directly related to this so wanted to check if anyone has had luck implementing an automatic "Storm Watch" feature with a Sol-Ark or similar Hybrid. Basically I want the system to automatically change my TOU battery discharge settings based on weather data...
