Currently exploring the options of have a sort of hybrid/two separate systems connected to one BYD 30.8 LVL battery set (2x 15.4 lvl units)
The reason for this is the DNO will only allow the current 6kw wind turbine and 2kw Pv system to be seen or connected to the grid
A application was made to add 2 x 5000kva multi plus 2 to the above to add a ess system to the installation. With the grid being connected to the input of the multi and going through the multi’s. So there would be power if the grid failed. The 2kw sma inverter was going to be installed in the output side of the multi and the 6 kw wind turbine which is a grid connected sma windy boy on the grid side of the muilti’s accepting in a grid outage the windy boy would be lost. But the DNO add all of these units together and the total is more then the 8kw they will allow
A ideal has been put forward to have this systems set up as a offgrid system with a suitable sized multi to run the house loads and have the 6kw windy boy and 2kw sma inverter (possible be changed to a fronuis) ac couple to this system.
So the above would change and discharge as a off grid system.
It’s also been suggested to add a multi only connected to the grid ( so the DNO see that sized inverter) on to the same BYD battery set for solely Battery charging. With this a scheduled charge off the installations cheap over night electrical tariff can be used.
just wondering how this will all play together?
my first thoughts are it wouldn’t work
but fill it could if there are two separate gx device and they were both able to allow to communicate with the ByD LVL at the same time
