Hi there

I had 2 pylontech up5000 batteries in the system and just added a third. 

What battery settings should I change ?

You shouldn't have to change any if you have the communication set up correctly already, just put the newest as master.

I am not to sure if it is correct. This is how it currently is.

Your dip switches don't look correct.

How should they be ?

On the first battery nr 1 is up. 

2nd and 3rd all down

Ok, that should not really make a difference, but ideally they should be the same on all the batteries:

You have to restart the battery for that change to take effect.

Thank you, will change them later when I get home.

You are using CAN communication so all the DIP switches should be OFF. (up)

Your voltage settings are all wrong and dangerously wrong- your batteries will be damaged and require new BMS's. DO NOT leave it on with these settings.

The settings should come via the CAN from the battery so it looks as if that is not working. Make sure pins 1-3 are not connected at all and you are using 4 and 5 (all at the battery end). For the inverter end look in your manual

3 x 2 pylontech up5000 batteries
3 x 4.8kWh
Recommended charge/discharge current is 50A per battery.
Which model SunSynk inverter do you have?

You have 100A charge / discharge limit
100A * 48V = 4.8kW
If you have the 8kW inverter, you could use 150A * 48V = 7.2kW to prevent clipping.

As per SunSynk manual, check LiBMS screen to ensure that the inverter & battery are communicating.
The Voltage Settings are ignored if LiBMS is communicating, but best to set them as per Pylontech recommendations of 53.5V
Also set 90 days to zero as conditioning is done by the BMS.
The shutdown 20% needs to be set with System Mode 1 in mind.
On mine, I have System Mode 1 of 20% and shutdown of 5%

Good day

I have a 5kw inverter. My system mode one is at 50%.

With a 5kW inverter,
Discharge/charge of 100A * 48V = 4.8kW is correct.
According to the manual, the UP5000 is

• Nominal Capacity (Wh) 4800 * 3 = 14.4kWh
• Usable Capacity (Wh) 4560  * 3 = 13.68kWh
• With 95% DoD (== 5% SoC)

With SoC 50% System Mode 1, means you will use 50% of 14.4kWh = 7.2kWh of the battery at night.
The inverter will shutdown if the SoC drops below 20%.
During night time & load shedding & battery at 50% you will sill be able to use from 50% -> 20% => 4.32kWh.
4.32kWh is the minimum, if the battery was at 60%SoC, then you will have from 60% -> 20% SoC.
The SoC 50%/20% is conservative (and probably good for stage 6).
I would use a shutdown SoC of 5% or 7%.
I would then consider also dropping the System Mode 1 lower.
I use a more aggressive 20%/5%, which means that I discharge my battery to 20% SoC daily which for Lithium batteries should be OK.
[Most nights I have 28-40% SoC still left unless it rained the day before]

The SoC 50%/20% is also dependent on the total battery capacity - you have 14.4kWh which is quite large.
A 20%/5% or 30%/10% will save more grid.

Hi, Its Bilal Ahmad have Three Inverex (8+8+8kw) nitrox Invertors, And Three Batteries Parallel of (pylonthic Lithium up5000x3)
