All things Sunsynk (Deye, Inge, etc...)

Just thought I'll post this. After a Year of checking settings and loadshedding, I have come up with this Loadshedder settings spreadsheet, matching the loadshedding times and the optimal settings for Battery charge/Discharge Times.

I have an 8kw Inverter, 5kw Panel production (Peak) and 10kw Battery capacity. Your environment might be different, but I have shared this with friends and it works for them - just find the Area in the Spreadsheet that correspond with your loadshedding schedule and this will provide you with the perfect settings for Work-Mode-2 on your Dye Inverter

I just want to check if I understand the time of use settings correctly.

Ours was set as follows by the installer:

So for each time slot the battery will be depleted until it reaches the percentage shown. Once it reaches that percentage or lower the inverter will start to use the grid to power the load. For the 17:00 - 19:00 slot the battery will be charged from the grid if it's below 90%. Is that correct?

In the worst case scenario where the battery is at 30% at 06:00 and load shedding hits (so no grid) I assume the battery will then deplete further until it reaches the 20% (I think that's it) shut off value.

The settings have to change to correspond with your loadshedding at the time, I have posted earlier how I have set my Workmode-2; depending on the loadshedding schedule at that time. Basically loadshedding changes every 4 days. I have found that approx once a week I change Grid charge from Time-slot 1 and 5 to Time-slot 6.
You don't have to set your Minimum Batt% to 90% - unless you are using lot of power between 17 and 19:00
Your minimum just have to cover your potential usage during that time (if it is loadshedding) so that your battery won't go below 20%.
Hence; I change these settings weekly because of loadshedding and when the Grid-charge are applicable depending on the loadshedding of the day.
Check my loadshedding schedule spreadsheet I shared earlier, that gives a no-brainer System Work-mode; but it has to be changed weekly.

With grid charge ticked it should charge batteries from the grid. If it's not ticked the batteries won't be charged, just the load will be covered by grid.

That would be the ideal, but at this stage the batteries are actually depleted to 30% by 6AM. I'm working on having the load during the night reduced a bit.

The main goal for the system is to limit grid usage as far as possible. Once load shedding starts again we'll re-evaluate what setting needs to be.

That's because your installer set it to 30% from 1AM - I set it to 30% only from 5AM (Maybe earlier in Summer/or depending on the loadshedding of the day). For early morning you need to keep some capacity in the batteries during that time, you only release (Discharge) right before the Sun will start providing recharge energy.

Thanks. We ended up adding a third battery and that solved the problem, plus gave us more than enough buffer to not really have to worry about loadshedding times (so far). At the moment the batteries only discharge to around 55% by the time the solar panels start producing enough to cover the base load again.
 
I have been offline for 5 weeks now. Logged tickets and spoke to support many times to no avail. This move from Region 1 to Region 2 is a total mess.
 
Got my first reconnect notification since install (about 6months), been on Region 2 from the beginning. Using an Android device.
 
We lost grid power after a thunderstorm fried a breaker and some cable last Tuesday, inverter + solar kept us up and running for the full 5 days it took for CP to come and sort it out.

However, since they replaced the breaker (on the overhead line here) and some of the cable, our grid voltage has gone from a consistent 235~245v (Pre outage) to the 250~275v range (post outage).

Suddenly I'm getting a lot of disconnect/reconnect messages even when grid power seems to be on - could this be the inverter disconnecting the grid side of things when the voltage goes over the maximum? We've logged a "Power Quality" call with City Power but who knows how long that will take...

We've also had the inverter reset twice today with an F34: AC_Overload_Fault - could this also be related to the high grid voltage? Because the manual indicates that this is when the load is more than the inverter can handle - but both times loads were only running at between 250w - 500w. Cannot see any way that we could draw more than 8kw even momentarily at those times to cause those faults.

The limitation is not just on the inverter. What's your battery capacity?

If you have 9.6 kWh (at 0.5C) of capacity, and the grid goes down because of load shedding it whatever, and your load is more than 4.8 kW (even momentarily), then it will trip with that error...

It's a 5Kwh Greenrich battery that's rated at 2c - so can handle up to 10Kw. The grid is also up at the time the error occurs, but it's over voltage (~265v). Geyser is off, stove and over are off. Even if both the fridge and chest freezer kick in at the exact same millisecond and have a startup current of 15x their normal draw, that's still under 8kw draw at the time.

Drawing more than what the battery can handle causes a different error. (We know this because wife tried running too many appliances during LS one time...).

It may be able to handle that, but what's your max discharge A set to? For each battery it's 50A at 0.5C, 100A at 1C, 150A at 1.5C. And I think the inverter has a hard limit of 185A in any event.

As for what could have caused it, speak to your wife. I've had it happen and it's always her...
 
Anyone seeing some weirdness with today's beta release of Solar Assistant?

PS: Seems like Solar Assistant fixed the issue with a second beta release for the day. All looks to be ok again.

Any suggestions?

Been running a SS 8 and 2 x r200 revov batteries with no problems for months. Last week I noticed my app and the inverter are only charging to 93% soc and then stopping. This is regardless of if I am using solar or mains to charge as I have tried both.

I have not changed any settings the only thing that I foolishly did and I can't say if this is the reason as I did not notice if the 2 coincided was that I switched to the solar assistant beta option but again I can't see that any settings have changed..

Appreciate any ideas

What were some of the issues you picked up?
 
Morning,
Woke up to this screen this morning on the app. Click on the"warning" nothing happens. Checked the inverter physically, all normal. I "assume" the App is wonky again?

The gateway is online

Same here, checked a few things but everything is normal, SunSynk strikes again with their unexplained nonsense :rolleyes: I am still trying to get their technical support to understand that I cannot see any of my data from Region 1.

Glad it's not just me. Thought I was missing something
 
I want to get the 8kW Hybrid Inverter SYNK-8k-SG01LP1 upgrading from a 5KW inverter.

How are people finding this? How user friendly is the web interface. I will have to check remotely for a large part. From reading the last few pages here it seems like the app is giving problems every now and then. Is this just recent or is it a trend?
