Hello, everybody,
a few days ago I got about 100 18650 batteries, which I now want to convert into a BusBar battery pack. Is there a recommended voltage for this? 8s, 9s, 10s? What have you had the best experiences with?

Maybe the whole thing will be connected to a Hybid Inverter later. (Will first be bought in one or two years when the solar system is upgraded)

What voltage system you going to run?

24V is generally 7s and 48V is generally 14s. That suits most of the inverters out there.

At the moment I don't know what the main DC voltage will be.
Since the conversion to a hybrid inverter will take some time, I don't know which type it will be at 100%. It could become a Kostal inverter....
I had hoped that "Triel and Error" might have proven a certain voltage. Then I better wait with the construction of the battery pack until I know which voltage it will finally be.
Until then I will simply read on quietly ;)
 
Its generally 24V or 48V. All larger than 2kW i highly recommend going 48V directly
