Contacted BSL, got helped immediately, four batteries bought Nov, Dec 2022 had firmware 2.05.
BSL updated it over the network to 2.14 and also checked the health status of all the cells. 

Here is mine on 2x7.2 kwh batteries. Enough to run the house for 14 hours 18h00-07h00 including one geyser cycle. Reason I dont discharge to 20% is to cover the occasional 4-8 morning loadshedding, using AC to top up a bit. Also using a loadshedding relay to switch of geyser in the early mornings to save on batteries. My settings are a bit conservative at this stage

spoken to Solar Assistant team, awaiting feedback

Both units were powered by the BLA batteries via the 10-60 v power supply. Will be switching to AC supply to separate it from the dc side.
The Orange Pi's doesn't use a sd card it's imbedded on the Pi. You can however still make a backup onto a sd card. The process is explained on their website.
Must thank Pierre from Solar Assistant for all his help with this issue

It seems to be an inherent design, both my Axpert VM 3 and max does it in SUB. Although at low power draw say 500 watt the utility will supply about 400 w, however once runing at say 2kw, the utility supply will drop of to almost nothing. I have never seen the extreme  Thaink is refering to of 1kW from the utility if theres enought solar.
