SOK Batteries for Victron Multiplus 12/3000

[garysclark]

I am looking to replace 4 lead acid batteries with SOK 206ah 12v batteries.
My system has a Victron Multiplus 12/3000 inverter charger.
I think I read in this forum that if I only have one SOK 206ah 12v battery, my inverter should not be larger than 1000W.
The Victron is a 3000W inverter.
How many SOK 206ah batteries do I need to purchase for my system?

Thanks

A 3000W inverter on a 12V system can result in 300A being pulled from the batteries.

The SOK batteries are rated for a max continuous discharge current of 100A. So you would need 3 (or more) SOK batteries in parallel to support the 300A draw. This is true of both the 206Ah and the 100Ah SOK batteries. So you might want to buy several of the 100Ah SOK batteries instead of several 206Ah batteries depending on how much capacity you actually need and how much you want to spend.

But do note that the MultiPlus is not a 3000W inverter. It is a 3000VA inverter which is 2400W. Since that can result in 240A from the batteries you still need 3 SOK in parallel to fully use the inverter.

200A*13V=2600W

X2 206AH would do the job.
