Thanks for the info Bloubul Will definitely keep an eye on this thread 🙂 JohnB

Have gone back through this thread again and see that Bloubul commented on how to do this

Tried the home-assistant-solaredge-modbus Integration from HACS and linked that up to the Wifi adapter by adding my Home Assistant servers details as the second server on the wifi adapter and appears to be working as it is picking up 1 Device and 83 entities. Looks promising, will see what the data looks like tomorrow

Is it possible to perhaps connect the wifi up to a local server using the TCP or UDP connection settings and send data requests to the inverter that way?

So, my question is. Instead of querying for the data via the RS485/Modbus connection. The WIfi Adapter that is on the Sunsynk inverter is already sending most of the data that we want to the Solarman server via the internet so that we can view it on the app. If I go to the webpage for the adapter (very secure password admin/admin) it has a page with remote server settings that have the default settings in them and then space for a second servers settings that I can edit. I am assuming that it will then send the data to that server as well (guessing things well above my pay grade here 🙂 ) Any one of you clever people know how to catch the data and see what is being sent, Node-red/InfluxDb/Grafan perhaps?

I am really looking for an easy way to intergrate my Sunsynk into Home Assistant so that I can control my Sonoff Ewelink devices based on what is happening with my inverter

@Denarius It is unclear from the website, what does this software offer me that the standard Sunsynk App does not, apart from running on a Raspberry Pi and perhaps being a bit more up to date, can't really see anything?

Seems that this topic has already been covered in some depth, found the post by Bloubul7 looks like he is doing pretty much what I would like to do 🙂

Was thinking of using https://esphome.io/ to manage the connection to the Inverter and switching on/off of the Sonoff's with Tasmota on them., Anyone had any experience or any other suggestions?

Does anyone know if there is an easy way to do this with a Sunsynk inverter (I know it is possible, I would rather just not be reinventing the wheel)? I assume that I would be connecting the Raspberry Pi to the CanBus or RS 485 ports on the Inverter using an interface of some sorts. I know that the ICC software is not compatible as it only seesm to work with the AXPert inverters. I am looking for a way to switch on/off certain devices on my power network when certain conditions happen on the inverter, Pool on when there is excess power, Borehole off when there is load shedding etc. I already have 8 Sonoff's installed so am reasonably familiar with them and happy to reflash them to Tasmota.

Looks like they have another site up https://www.thewattstorsa.co.za/ Same batteries, no payment via credit card, optional CANBUS connection, different phone number Domain created Nov 2020

Hi Guys I am looking for something along the lines of the ICC APM software that can control Sonoff devices based on what's specified events on a Sunsynk Inverter. My understanding is that the ICC software is not compatible with the Sunsynk inverters Specifically I would like to disconnect some items from drawing power when the Inverter detects load shedding. It is unfortunately not possible to add them onto the non-essential loads. If there are any other suggestions as to how I could accomplish this I am open to suggestions. Thanks JohnB

They have a new site up, same pictures as the old one https://www.bestsolarsolutions.co.za/ R50k for 24kw of battery

Hi Leslie, Thank you for your review of your ESS System. You could perhaps look at a "soft starter" for your compressor which does not require the boost of electricity to get going. Speak to Neels at https://www.cfptechnologies.co.za/workshopspeedcontrol/ and he will be able to advise what will be suitable for your application. Otherwise from RS Electronics https://za.rs-online.com/web/p/motor-starters/2096340/ JohnB

Have an Efergy Engage already which probably gives me enough info about my energy usage 🙂 I liked that the Sense will isolate the power usage to a usage by device. Was wondering if anyone has any experience with it.

Hi I was looking online for energy usage monitors and saw this recommend in the US on CNET, has anyone seen these locally/tried one out? I am interested to know what the usage of it is like as it looks very granular on the usage reports https://sense.com/ Thanks JohnB

Thanks @Vassen, seldom pull more than 2kw at night so don't need batteries to run a 10kw load. The large PV panel array would be to offset non-essential items that I would like to cover during daylight hours with my PV panels when funds allow. Thinking of starting with a 5kw Inverter and then I can slot another one on later if I want rather than spending the extra for the 8kw out the box.

Can someone tell me, I am looking at either a Sunsynk 8kw system or a 5kw and then perhaps adding a second 5kw on a bit later. If I have 2 x 5kw Sunsynk inverters in parallel, would that allow me to connect 2 x 6500w of panels using all 4 mppt controllers or are there some restrictions when using the inverters in parallel? Thanks

Thank you @Achmat & @Vassen for the correction. I assume that you would have to have a sensor in place so that power is not fed back into the grid, is that correct?

David Potz also runs in Parallel

So, this is my understanding, please note that I am no expert on this and would like to hear from anyone that knows more about it than I do. It is obviously not an option to have batteries of different chemistries connected in parallel due to different operating voltages. From what I understand, the state of charge of the battery packs running in parallel will always be the same as long as they are connected together and the amperage supplied will be in proportion to their capacities. The way it was explained to me was to think of it as having a number of water tanks of the same height (voltages) but with different diameters (capacities) connected in parallel. The water levels between the tanks will always be the same and when you draw water out of them they will both drop their levels at the same rate or fill up at the same rate. There are obviously a lot of complications that happen as the batteries are being independently managed by BMS's So If you have a 10kw and a 5kw pack in parallel, the 10kw will contribute at twice the amperage as the 5kw. You will be limited to the BMS with the lowest supply amperage in proportion to it's capacity So, in my example if both the 10kw and 5kw banks are able to supply 100A, the 5kw will only be able to supply 50A as the 10Kw will be supplying 100A, so max amperage for the paralleled banks will be 150A. If you go over that the BMS on the 10KW pack will disconnect as it is supplying more than 100A and the power requirement will switch to the 5kw causing it also to disconnect. There are all sorts of complications that can happen as a result of having your packs go out of sync and being at different states of charge and then trying to reconnect resulting in uncontrolled current flows Have been thinking about it though and think I can understand why the manufacturers would not be keen to have packs not designed to run together in parallel doing so. I think that as long as you understand the Amperage limitations it should not be a problem as long at the voltage settings of the BMS's is the same and the battery chemistries are the same. Only hurdle to overcome would be making sure that the pack voltages are the same when they are connected in parrallel. JohnB

I know that the Mecer 2nd life 12V batteries explicitly will not allow you to put them in parallel. ou can have them in series without issue

The only problem with this setup is that the inverter cannot power the non-essential items with power from the PV Panels. Non-essential items will then only be able to get power from the grid.
