Good Day.
Trust you are doing well.
Need advise of the experts. My question is simple.
I understand that a 5 KWh lithium battery can be used upto 80% in most of the scenarios. If I use the 5KWh battery that has a 1C discharge means in one hour I will be able to burn 4KWh. At 0.5C discharge I will be able to burn 4KWh in 2 hour.
Just to say it otherwise with 0.5C discharge, in one hour max output from battery will be 2.5KW.
Now to the above scenario I am adding an 8KW inverter. I want to be able to run the inverter at full capacity. What I mean is, I want to run the inverter to be able to run 7kw or 7.5kw load when there is no eskom and no sun.
With one 8KWh inverter and one 5KWh battery at 1C discharge, I can only run the 8KWh inverter to run loads worth 4KWh as thats what we can do with one battery until BMS shuts down.
Now to the 8kw inverter and one 5KWh battery(1C) if we add another 5KWh battery(1C), can the inverter draw 8kw of power for 1 hour if there is enough load?
Or will the inverter only run max load of 4kw before BMS shuts down the battery at safe cut off of 80% discharge?
in principle series connected battery has its voltage added and current remains same and in parallel connected battery, voltage remains same and current gets added. With this principle will the two 5KWh batteries be able to discharge 8KW of power at 1C each in parallel when connected to an 8kw inverter resulting in 8kw of output in one hour subject to condition that there is load that are on the inverter?
