All very nice to have - but what do you actually use any of that for?
Also, most of that is available via HA too

From what I can tell, there are some practical advantages:
  • You can write values to the inverter, so I could make decisions about whether to charge the battery from grid based on whether there's load-shedding coming up for example. (I know that I can adjust settings via the Solarman app, but I can't see that the HA integration has that ability, if it does.)
  • Faster response, solarman updates once per minute, if solar-assistant can be faster than this that would be great.
  • Not relying on a cloud connection, in fact if you prefer you don't need wifi at all, you can plug into the ethernet. For the tinfoil-hat-paranoid, there are advantages to this.

I'm an electronic engineer by profession so if I weren't lazy, I'd get an RS458 cable and talk to the inverter myself directly. But I'm lazy, I'd rather spend some money and buy a product.

All of those points are covered by HA too, except the lan cable option.

For me, could not be bothered to wire up a whole new interface and cable. My HA is virtual and also 25m away from the inverter so getting that RS-232 or whatever the Kellerman interface requires would have just made it more complicated for me.

Simplicity and realtime updates at the big draws and in my case I had loads of pi's with WiFi dongles doing nothing.

It is really great value for money. They just need to be faster at a few things.

I am certain they will also allow the automated changing of inverter settings based on SoC and expected loadshedding schedules soon. That would be a boon for many who are not even in HA.

While I have the sunsynk dongle still connected , I only keep it plugged in as that is the device that knows the full Stats of my plant as I only got solar assistant a month or so later after it was installed .

I'm obviously missing something here. You say you could not be bothered to wire up a whole new interface and cable, but isn't that exactly what you've done for SA? The HA integrations are wireless (either via existing solarman dongle, or via an ESP32). I guess if one already has a pi lying around it changes the equation a bit, but most people seem to be buying the hardware for this too.
 
Trying to find a post on a summary of the Sunsynk inverter options.. do i have this correct:
Tick "Zero Export" and "Solar Export" = Power essentials, and non-essentials and feed into grid
Tick "Zero Export" and "Solar Export" and set "power limiter" to 0W = Power essentials and non-essentials
Tick "Zero Export" and "Limit to load" = Power essentials only

On Battery settings, if i have 2x Sunsynk batteries, then I can safely set the max Charge to 100A and max discharge to 150A?
If grid charge is, for example 60A, then when conditions are right it will charge 60A from grid and 40A from PV directly for total 100A?

I've got HA and solarman at the moment (was provided by my installer) and I can't figure out how to write settings to the inverter, it doesn't seem to be possible.

The example I gave was deciding whether to charge batteries from grid overnight based on whether or not there'd be load-shedding between now and when the sun comes up. Currently I don't have that.

The other thing that I'd like is a faster readout of certain values, not all perhaps but some. Like the current load - I have everything on essentials like you do, but I switch my geyser off if I detect higher than a certain load. Currently, if someone switches the kettle on it could be up to 59 seconds of very high load before solarman updates. So far it hasn't been a problem but I'd much prefer if home assistant could react within a second or two. I could achieve this by reading from the RS485 myself, but Solar Assistant has done the hard work for me. So it's on my wish-list at the moment.

I'm also finding solarman a little bit flaky. Here's a screencap from HA for my battery SOC:

Sometimes it just doesn't update properly for a minute or two, and it just has zero values. As you can see it's happened 9 times so far today. Ultimately not the end of the world but I'd like more reliability.

You need to add something like this to enable HA to change inverter settings

Quite. Solar Assistant does all this for you - so you don't need to go and find an esp32 and the right cables.

It's all good though - if you prefer to take this approach, it looks like a nice tinkering project. It's good that there are options for people who want to explore them. Ultimately whatever works.

Yeah. The one costs R3000 and requires an extra device and cabling, the other is about R150 and fits right inside the inverter.

This video is quite well done

This only works with 3 phase inverters.

Although, I believe I posted a ESP solution previously that works with DEYE

My main drive for Solar Assistant was the ability to react to over usage faster - and configuring the inverter with home-assistant automations. (e.g. every night the work mode is changed based on the forecasts and loadshedding for the next day)

R150 and a whole lot of faffing.

I do electronics for a living. The last thing I want to do is more electronics in my personal time. I'll pay the R3000, just plug it in and be done.

I'm not arguing against the existence of other alternatives - different people, different needs, different preferences, different budgets. There's room for everyone! I'm just giving my opinion.

The guy in the YouTube channel I posted above also has a working esp solution for Deye (it might be the same as the one you posted). My point was simply that one can get all the benefit of SA for a fraction of the price. I believe the ESP connections are real time too. I'm not sure of the exact timings etc as I don't have a use case for this. The 30 sec update interval is ample for my requirements and I can't think of a need to change inverter settings. For those who do need that, then there's the SA or ESP option. The latter is considerably cheaper.

Choice is also good, would suck if there was only 1 way to achieve the goal whether it was only SA or only ESP
 
Where can I check that my sunsynk 8kw uses both batteries that is connected

Revov shows 4 light indicators and other shows 6,only realized this now as walking past

Checked on their screens and both are not on 99%

I only have sunsynk app to check inverter which shows 99% soc as well

Used as backup, no solar panels

Please help

No solar assistant is plug and play. I bought the software, the two cables , flashed the SD , connected the cables from the pi to the inverter and battery, basic config, and the data was in HA.

Please also note, I have a sunsynk dongle which means I still needed to do something extra for the Kellerman integration to work if I recall from reading at the time.

In addition, I was not going to go and find an ESP32 board ,etc. I just used mostly what I had .

Also with my installation , it looks clean and doesn't look dodge (I mean that with no malice) as I guess an ESP32 would look next to an inverter etc.

Plus: it's been rock solid reliable from minute 1 of go-live

Yeah, as I mentioned earlier, it makes a heck of a lot more sense if you already have an unused Pi lying around.

Also, I'm pretty sure the esp32 will fit inside the inverter quite comfortably so no reason for it not to look squeaky clean.

Nah, just trying to understand why people are shelling out almost R3k for something they can get for R150.

It's like a lot of things, you pay for the ease of use. It's a plug and play tested solution that has excellent documentation, quite a large user base and requires minimal tinkering (except for plugging in the cable to the inverter).

That's obviously a lot more attractive for most people than MacGuyvering their own solution.

If you put it that way, I think I might have just seen a little weekend hobby business opportunity.
