Sunsynk Inverter configuration questions

I have ordered my Rasberry Pi from Amazon and while I am waiting I would like to gather some information with regards to what information do you think I require in order to make informed decisions? 

 

1. Home assistant application (Automation Platform)  

2. Node Red (Advance automation)

3. Integration to Synsynk platform for information and also to change/update inverter settings ( Which Plugin or application would you recommend) 

4. Loadshedding Schedule  (Which Plugin or application would you recommend) 

5. Solar prediction Application (Which Plugin or application would you recommend) 

6. CBI Astute Controller integration to switch on/off devices

7. Weather information?

8. What else?

 

What would I need to include in the dashboard view to get a overall integrated view on my energy consumption.

What is all the decision logic that I should implement?

I know there is probably already a few people that has done the integration already and I would love to see your solution or have your input?

Thanks

There is honestly so much, depends on your wants.

A suggestion is https://github.com/slipx06/sunsynk-power-flow-card for your dashboard

    Ok, so first a summary of my setup: 8 kW Sunsynk inverter 2 x 5kWh Greenrich WM5000 wall mount batteries 10 x 555W Longi panels, for a peak of 5.5kW nameplate capacity. Al

    So in summary, on a normal day like today, with lots of sunshine: Some things to note: Not sure what that 01h00 spike is. Need to figure that one out.  The 04h30 geyser boost

  • Change around your CT coil wires in the inverter or install the CT coil the other way around as its not the right way.

I strongly recommend kellerza/sunsynk for local integration that is not affected by Internet outages. FWIW, you don't have to use an RS485 dongle if you don't care about having the Sunsynk WiFi dongle connected at the same time - you can use a RS232 adapter to the WiFi dongle's port, which works just as well, and has less likelihood of complications due to the specific RS485 adapter you have chosen.

Some things to note:

  • Not sure what that 01h00 spike is. Need to figure that one out. 
  • The 04h30 geyser boost took place, and pulled from the batteries because the grid was off.
    • This is not ideal, a cooler shower is preferable imo, but there is no way for me to avoid this, unless I wake up at 04h30 to switch off the geyser.
  • Batteries were fully charged by 10h30.
  • The coffee machine morning spike came from the grid, because the batteries were <50% SOC at this time, so the inverter did not allow it to go lower. 
  • The spikes you see above the geyser's 2kW draw include the dishwasher, washing machine and other things like kettles. 
  • 15h50 spike was the airfryer, lunch.

On a less than nice day, where it's either raining the whole day or cloudy, things might look like this:

image.thumb.png.0813dfa4a639bb568f387a5286da65bb.png

Notes:

  • Geyser still comes on in it's given time slot (hot showers are important!), but now the inverter uses a blend of solar and grid to do that, because there is not enough PV do it alone.
  • The inverter brings the battery up to 75% as per my settings, and uses grid in this time to power other loads. Once it's at 75% it stays there, and uses grid to power my loads, as I had a massive rain storm at this time and PV was uncerperforming.
  • In the late afternoon, the sun came out, and topped my batteries up to 100%.
  • We decide to cook something in the oven at 1730, and the batteries crashed back down to 75%, and the inverter held it there till 20h, using grid during this time.

Thanks! I have also found this very useful! My problem again is that I have a sub db in an outbuilding from where my borehole and pool pump runs. My borehole is used at different times day and night. Maybe I must put that whole load on AUX but that means that without PV power I cannot use the borehole, is my understanding correct. The AUX will only use PV power? 

Hi all i am Shane from SA installing 3 8kva single phase inverters and connecting to a 3phase house my question is when coming out of my change over can i then take double pole circuit breaker to each inverter and ,each inverter will have a double pole input and a double pole output and it will be sent back to the house or is a tripple pole the right way there is ni 3 phase equipment in the house your input would be greatly appreciated 

Hi guys, same topic, similar issue. 

Hardware: 
Sunsynk 5Kva
2x Pylontech 5000 
4.6Kw Pv Input

My question is the following. 
Up till Sunday, PV Was supplying loads(including non-essential) unless Load went higher, then Grid supplemented load. 
Battery was constant at 90% SOC

After adding second battery on Monday, 
I'm now only getting PV straight to the batteries and NONE to the load/non-esssential (if pv in excess)

No settings have been changed as far as I'm aware. 

Would appreciate if somebody could give me a list of all settings to be checked with regards to the above issue and guide me to the correct settings for my configuration.

Hi @Red Falcon,

It might be easier if you provide screengrabs of your current inverter settings:

- Battery

- System Mode (Tab 1 and Tab 2)

- Information screens

 

Thanks

Any Suggestions? 😅

 

You can disable zero export and check if the CT is connected the right way around.

Perhaps you should update the battery firmware and inverter firmware.

A factory reset could also be on the cards.

CT is the right way round. Does not give Negative Value. 
Remember that the system was running perfectly and then all of a sudden started doing the issues i mentioned in the previous posts.

So from that chart, it seems a 6.6kw Sunsynk inverter can handle the load right? Do you ever go beyond 6kw? Don't get me wrong i still think 8kw is the best as it will not overwork

Try to un-tick grid charge on the Battery Setup page.

Okay done, unticked. 

How do i get my battery to stay at 90%. 

It started going to 100% since Monday with all the other issues. 

So basically i want it to feed load up to a ceratin percentage and then the rest from the grid during the night. 

Eg: Would like it to feed the 10% from battery when excess PV goes away and then the battery must stay at 90% during the night.

What is it doing right now? Show the System Flow Chart again.

According to your settings if you start with a 100% full battery, I suspect it should now be drawing power from the battery until you get to 90%. Turn on a heater or something to make it go faster to see if it works. Suspecting that since you had Grid Charge ticked, the inverter was keeping the battery at 100%

Is battery output supposed to be higher ?

What am I missing ? 

Are all my settings I posted above , correct ? 

On the system mode - > mode2 untick 'soler export'  then to test tick 'Limit to load only' the inverter should then send battery power to your essentials only. Did it work?

Nope. Still the same 🙃

If you move your geyser to non-essential then it won't switch on when the grid is off. If the grid is on then the geyser will still be powered by the batteries as long as your export settings are configured correctly. 

 

From the graphs it looks like your geyser remains on at appropriately 2kw for a large part of the day. This seems strange.
