No worries, as soon as the sol-ark 19k comes out, no one will settle for a weaker 18kvery possible, spinup a tale press it lightly amongst the various forums and the unknowing would be probably believe anything.

Still waiting for direct links to all these people abandoned by Solark support....should be easy enough....very possible, spinup a tale press it lightly amongst the various forums and the unknowing would be probably believe anything.
How about a good story? Sol-Ark support took a while, and it wasn't exactly "smooth", but in the end, they upgraded me to a free 15k all because my 12k was getting hot, but still functioning as it should, I just wasnt perfectly happy with the unit.Still waiting for direct links to all these people abandoned by Solark support....should be easy enough....
The ad ( propaganda as someone called it, lol) is confusing. Is it a credit of 1k towards the purchase of an 18 or is it a total price of 1k for an 18?If someonetakes advantage of thisgets taken advantage of, they have to pay return shipping to send their Solark back...
Who would even consider this? I can't figure it out and I've been trying to make sense of it for deyes. Seems like a money maker for EG4 to me, what's a used 15K go for...

The way I read it is you get the 18K for $1,000. If you do not send your 15K within 6 weeks then you are charged the full amount.My interpretation is 1k off the price of the 18kpv after you pay to ship a working 15k back.
Yeah, in the call the SA rep said eg4 bats with SA in closed loop by itself would not void warranty. But if it was determined that EG4 batteries, in closed loop ops, were the cause of the inverter malfunctioning, the warranty may be voided.
SA rep mentioned there were instance(s) eg4 bats wrote to SA registry. Since SA has not tested eg4 bats in closed loop, they can not 100%, unconditionally provide both support and warranty. Again, reasonable and as expected out of any manufacturer/distributer/retailer.
I noticed you ended that with a question mark. Did they confirm the warranties are intact?
I would just like to know what significant issues they’ve had when people use EG4 batteries in Pylontech protocol. I’ll try shooting them an email.
No idea what the SA rep meant when he said "registry". Could be any logging data.Why would a manufacturer let a third party battery write anything to the "registry" directly?
Wouldn't anything going over the comm ports be vetted by the inverter firmware and written into the "registry" by the inverter itself, formatted into whatever fashion it considers safe?
What data would a third party battery be sending to the inverters comm port that would damage the inverter?
Is this another of those instances of claiming bad voltages / grounding on a comm port damaging an inverter, like the EG4 and Solar Assistant fiasco?
Physically, how would a third party battery damage an inverter by closed loop settings? Does the inverter blindly trust everything a battery says and do it with no sanity checking based on it's own limits? I suppose a third party battery could lie about it's true state of charge, telling an inverter it has plenty of available capacity, prompting an inverter with ac coupled solar to try to dump current into the battery.. then the battery says, "oopsie, I had no available capacity".. causing something to blow up if the inverter can't react fast enough to the new reality. What other scenarios are there? Let's brainstorm some.

But I can very well see how the BMS in the EG4 wallmount bats' default settings could conflict with most inverter settings.
At the extreme, but still within reality, the BMS could let the cells get to (true) 3.99V and 2.185V and/or total pack voltage at 43V-63V before bms would cut off. (3.8V or 60V * 1.05%.) . The one thing I don't see is at what Voltage will the bms start balancing. I'm assuming its near 3.45V, I really don't know.... anyone???
In an extremely unbalanced state a single cell could get to 3.8V and the low one could be <3.0V.
For a user to not intimately be aware of individual cell V, this could be a recipe for disaster. Frankly, I do not trust SOC nor total V readings w/o cell level V data. Imagine, 4 Packs running at near max power, and 2 packs cut off suddenly due to bms shutdown for inaccurate SOC/V total.
DC amps double, remaining packs may not deliver and shuts down, inverter needs to switch to AC to supplement, those relays are making full power connections. imaginethat cycle of on/off as resting Voltage recovers.
This is just a simple example I can think of off the top.
Exactly and I have said that on this subject before.Does the inverter blindly trust everything a battery says and do it with no sanity checking based on it's own limits

Are you serious on the relays? That is a disaster if true.It's not just battery communication issues, they are also apparently welding grid bypass relays shut, now that is a very serious problem.

From what I have heard, the issues arriving with EG4 batteries and Sol-Ark Inverters is due to them (EG4) incorrectly using the SOK protocol that they emulate in order to talk closed loop with Sol-Ark. Pretty sure this would not happen with an open loop comms configuration. The crux of the issue being that EG4 batteries somehow modifies something in the Sol-Ark it is not supposed to, and thus, their memory or filesystem gets corrupted. Know a guy who is helping with my project and I told him I was planning on using EG4 and he said he no longer uses them due to multiple units that he manages failing when using EG4 batteries and sol-Ark. So, for me anyway, I am looking at the Pytes V5 or the Pytes E-Box 41800R Batteries for my system.SOLARK -
"because of significant operational and functional issues that have arisen with non-approved battery vendors (including, among others, EG4 batteries)"
EG4 -
"people who want to swap for for an inverter that will be warrantied before their's fails"
"warranty has been fraudulently voided by their inverter company"
Both companies are acknowledging that something fails or doesn't work operationally and neither one wants to say what it is. Its apparently failing to the point where the unit needs repairs, otherwise warranty (or lack of) wouldn't be discussed, right? Good grief whats the big secret!?
Transparency is needed here; your customers have thousands of dollars in equipment on the line.

Sok doesn't have their own protocol, it uses pylontech, just like Eg4 and about 90% of all batteries..From what I have heard, the issues arriving with EG4 batteries and Sol-Ark Inverters is due to them (EG4) incorrectly using the SOK protocol that they emulate in order to talk closed loop with Sol-Ark.
