Hallo 
The luxpower inverters are great inverter, especially the remote settings option.
 
Inverter BMS reader sometimes read incorrectly or slowly gets a lower reading, stating 50v is 100% SOC.
Hubble am2 batteries, Work around is to manually put inverter to lead acid mode, unit will restart. Manually input the full voltage, charge full, then go back to lithium setting.
Note, every time you change the battery type, the charging times reset.
I find splitting the times, aka on off 1 and use on off 2  works better then try to set for 24h. 
Say 12:00~23:00. Then 23:05~11:55
5min gap for relays to change, luxpower inverters are in no hurry to click relays.
Happy charging.
 
 
 

Hi all. Managed to commissioning the paralleled units successfully. Thanks for the help. Just waiting for panels due to stock shortages. 

From the Dyness manual the setting for the master is correct but the slave has to be all down. The cabling also needs to be amended to function optimally - you can leave the red as-is but the black would then need to go from Inverter > Slave -ve > master -ve CAN cable from Inverter into IN port on Master then cable from Master Out to Slave In These batteries work 100% with Deye in Lithuim mode  Source >>https://solaradvice.co.za/wp-content/uploads/2021/10/Dyness-5-12kWh-BX51100-Lithiumion-Battery-UserManual.pdf

There are two aspects to this.
A normally open contactor/relay should be installed such that when eskom power dies (input to inverter), the contacts connect (output of inverter) earth and neutral. Now you have a local power plant earth/neutral bond which is a requirement. It MUST be temporary, because when eskom plant comes back online, then you must use their earth neutral bond (Always use the bond closest to the power plant (Power source) that you are using. You are not allowed to have two permanent earth neutral bonds in a system.
However, if eskom is available, and your battery is in island mode (Working off battery or solar) then the contactor/relay remains open because eskom is available, and you still have no earth-neutral bond. To fix this, ensure that your inverter is in "Hybrid mode", this keeps the AC Input active/connected even when using solar/battery and hence, the bond before your inverter is still in play.
I had an electrician sign off a C.O.C BEFORE this was done! No Bond and NO earth leakage, yet they signed off. Crazy
I forced them to come back and solve as per above.

Where are you located? The cable appears to be a normal over the counter cable 1-1 2-2 3-3 4-4 5-5 6-6 7-7 8-8 
 

Thank you so much. I forgot to respond with gratitude.

Perhaps time to do the not normal thing by using manual settings to charge those flat batteries.
Error 52 just tells you the DC bus has low voltage. In the current rainy weather you cannot rely on PV to charge them. In a previous post you indicated you want to use more PV for load and you have used the setting CSO. Perhaps time to use SNU. Bear in mind if CSO is used and there is just a trickle of PV it will not use the grid. PV has to be zero to charge the batteries. This should have taken place during the night but did not. It might help to switch off the PV input in order to force grid charge.
So it is time to try something else. If it was me in you situation I would disconnect the comms cable between inverter and battery. Without know the detail settings of a Growatt I would apply general settings for 16 cell lithium batteries.
Here is a guideline for lithium and other members can give their input:
Back to grid:  48V
Disconnect battery: 46V
Bulk/boost charging: 53V
Float: 51V
Equalization: Set to off or a very short 15min
Low volt warning: 49V
Try these and see if you can get those batteries charged.
Due to the ongoing problems it might be a time to get those batteries charged and see if they can power a kettle without dropping a lot in voltage or connecting to the grid.
Should this fail to achieve positive results it's time to call in another installer to check out all the connections and settings. Not easy to give guidance without know how the panels (strings) are connected and if the work correctly.
