By the way if you have what might seem like a "stupid" question and send a pm and hopefully I can answer the question or post in this thread and see if someone can answer the question.

Something I believe the product supplier should arrange is the firmware update (if the unit is not up tod date) and a commissioning sheet will all the relevant setting for the setup that you are going to install.
I dont know why they dont already do it, it would save many a frustrating call to call centres.
Anyone figured out what BMS_Err_stop is used for? Why would you tick it under battery setup - battery type ?

Hopes it help
Installing these units are like playing with that block we had as a kid, where you had to fit the star into hole that looked like a star, the square in to the square hole, etc.
There is a specific procedure and so long as you follow that procedure and tick the right block and check the limits, anyone can wire and program these units.
Once you have done one and understand how to setup the unit, you have a commissioning sheet you are basically a master installer. Its just finding someone to teach you the basics.
Hopefully by the time I am finished running through every setting and gone into detail from the basics to setting and understanding the system mode everyone will have a good understanding of how to setup and fault find a Sunsynk inverter and battery.
I have a video in which Keith from Sunsynk explain every setting and explain what it does. It helped a lot in understanding what it is all about. Also the traing manual goes in detail om the various settings. I guess Sunsyk think all installers have years of experience with Sunsynk and all of them is qualified installers that knows the setting out of their head.

An 8 kva inverter with a 5 kwh battery. It was time to add a battery.
Simple, when you know how.
Switch off the battery, connect all the battery wires taking note of the cable size and the charge discharge current. An 8 kva inverter can charge/discharge at 190 amps.
The battery terminals for a 5 kwh battery can only take a 25 mm cable, so make sure your fuse is correctly rated.
Once you have connected both the batteries in the configuration you require, in my case it is parallel cascade using a 125 amp fuse, to protect the system until I fit the additional batteries.
we will go into more details about that once I build the busbar fuse system for the completed unit.
You then need to add a comms cable between the master and slave using the in and out ports. The comms cable between the inverter and the will remain in the can port.
This is what you need to know:
You dont have to fully charge the new battery.
You dont have to balance the batteries.
There are NO dip switches on the IP 65 Sunsynk battery. So ther is no dip switch settings required.
You have to shut down the entire system, both batteries batteries and inverter.
If you only switch off the master and connect the slave battery, then switch on the master then the slave, the battery will not communicate with the inverter.
If you go to Libms, you notice that you have lost your battery communication.
Once the entire system is shutdown, inverter and batteries, you then switch on the battery you want to be the master wait until all the lights stop rolling and only the top green light is blinking, then you switch on the slave, wait till lights battery lights stop rolling, then you switch on the inverter and wait until the green light "normal" is on. At this point you can go to battery Libms and check if there is comms. IF everything is in ok , you will see the screen with the battery details.
You can then switch on the mains and the non essential.
You can do this a lot faster and not follow this procedure, trust me I have learnt, rather be patient and follow this procedure if you dont want to call the UK to get patched through to hong kong then china and back to SA
Also what I learnt is for example the 5kw is 6500 maximum watt peak of panels.
Now if you take the 13A x 500V you get 6500. BUT this does does not mean 6500wp per MPPT it is the total.
So basically you can not exceed 6500wp with both MPPTs so then do 3250WP per MPPT.
Now I am still trying to confirm this as I would love to put 6500 on each MPPT, so one MPPT North and the other east to get the evening sun.

I have heard over the grape vine that Sunsync will no longer be imported, but replaced with a number of Deye models. Note not all Deye models are IP65. Check the specs before purchasing.

I find this hard to believe, considering the lads from Sunsynk will be visiting SA soon to launch some new products. Maybe the plan is to integrate Sunsynk into Deye or the other way around.
I would verify this information with the Sunsynk supplier who supplies all the wholesalers and most of the installers with Sunsynk products.
They both come out the same factory, its only the software that is different.
Maybe Deye will be supplied with Sunsynk software.
It really makes no difference, same quality, same factory.
