My issue is resolved for now: 
Had the same issue and was advised as follows:- 1. Ensure you have the latest firmware 2. adjust the charge voltage to 54,6 3. Set ac charge according to SOC 90-100% and not time.   I was told, by Luxpowertek: “EPS voltage high issue during fail to limit output when grid fail, and grid frequency changed a lot” Hope this helps. Seems to have worked in my case
 

Hi Ben 
You welcome to give me a call on 0824515786

Did you use a standard network cable or the one supplied.  In both cases the pin out configuration would be incorrect.  You will need to make a comm cable with the following configuration: 


 
Also make sure that the Dip Switches are correct. Usually Dip 1 is ON
Below is just a photo  to indicate the nubering on the RJ45 plug

Had a similar call from Coronationville.  Pastor Andre Manicomb 0832955479.
Fortunately, I refused a COD transaction and stated that I was happy to collect the funds and deliver thereafter.  no contact after that.  
I seem to also be getting lots of fraudelant messages from Facebook Messenger.  When checking the profile pictures and then calling them, there appears to be a mismatch with their profile photos and the accent on the line.  I make certain I call all customers before concluding or doing a transaction.  Lots of thieves out there.
 
Sorry for your loss, it is very difficult to loose your hard earned money to the unscrupulous individuals.
