@bandgap - Curious, what model panels did they use?

@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.

Has anyone brought this issue to Sol-Ark's attention?

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'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...

@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 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...

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.

Also, seems at least theoretically possible to access the data locally. https://github.com/Koenkk/zigbee2mqtt/discussions/18020 Any great programmers on here that want to help?

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...

It's a good point. I guess worst case you get up on the roof and start unplugging. You are motivating me to run an experiment. Does the system actually need a CCA or does it just need power to the TAP to stay alive. If it's the latter, you could just power the TAP directly.

No - I guess I was assuming it was the same as the Tigo TS4-A-O which does RSD but also optimizing and monitoring. It would be great if the Tigo would allow local data access but that doesn't seem to be in the cards. I was thinking the APSmart was similar but I guess it is more like the...

Does anybody on here have actual experience with the APSmart RSD and their cloud platform?

This is all being displayed with Grafana+HA, correct? Also, you mentioned you are doing V2H ? How exactly?

Are you teasing me? Please do share how this is happening on the backend

And does it go back to your regular profile once the storm has passed, or do you do manually?

@ChrisG , can you share the basics of your automation script in YAML, I was in the process of doing this but never got to the finish line. Btw, in response to @nuke above, it appears SA is needed since it can write directly to the Sol-Ark mod bus registers, where HA cannot.

See this thread https://diysolarforum.com/threads/sol-ark-8-12-15k-with-tigo-ts4-a-o.45069/

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...

I haven't set up HA yet, I'm just running solar assistant currently. I forget to manually adjust my battery discharge profit before a storm the other day, the grid went down and I only had 10% left in battery ! , so I'm trying to dummy proof my system. Once I get HA running I'll report...

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...

Hi, I'm just getting my Sol-Ark 15 with Tigo TS4-A-O ready for AHJ inspection. Question - Why is using this relay and connecting the CCA to the Sol-Ark necessary at all? Can't you can just wire a NO button directly to CCA Aux to achieve rapid shutdown per...

Personally I find all of these discussions highly entertaining. One of my main take aways is that things are more gray than we as humans would like them to be. I'm inherently distrustful of people who claim with 100% certainty that something is the case when it's clearly not 100% certain...

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...

Are you thinking your statement from earlier "If SolArk designed the hardware, then contracted out manufacturing, that would be very significant", might be incorrect ? ;)

That is an interesting read. Looks like they came to a settlement, case dismissed! https://www.pacermonitor.com/public/case/43206471/Portable_Solar_v_Lion_Energy Anyone care to guess what happened in the case...

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...

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

@jrcromer How does Sunsynk fit into the equation you described above between Sol-Ark and Deye?

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

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

Wow, that is a really nice setup. I'm definitely not an expert, but from the morsels of information I've gathered on this forum I would think you need additional over current protection as all those batteries can end up flowing through one wire in a short since they are paralleled.
