Greetings
I have putting together my setup and recently received my Multiplus Compact, what a nice unit! After inital configuration i discovered that in the charger settings aren't conducive to Tesla LiIon batteries.
Question 1: Does anyone have this battery, what settings do you set in the charger tab?
Question 2: I have AC In connected, is there a way to prioritize solar over AC In?
Thank you
I'd use:
-charge voltage (in old terms: absorbtion) 6x 4.1 V = 24.6 V
-float I usually set a little bit lower to prevent trickle charging: 24.6V (or 24.5) [edit, this was first a typo, adjusted)
-discharge voltage: 6x 3.3V = 19.8V
Pleas note: a battery protect only works in one direction, and is not adviced to use between battery and inverter.
What BMS are you going to use?
I'm not using a Tesla module myself at the moment, but other 6s battery modules with Tesla BMS slaves (plus SimpBMS)
Thanks Boekel.
I will use those settings.
So i should remove the battery protect from in between the battery and inverter? Where should i place in the diagram?
As far as BMS, I am still waiting for the Batrium WatchmonPlus which they promise it will manage these cells. I have also looked at Tom's simpBMS, i've asked him, via PM, if he has any in stock. I am not sure however if my slave (see below) will work.
Please note that 25.6 is way too high for these modules. 25.2 is the max they should be charged at, and even that should be avoided. Is that a typo or am missing something? :)
I personally would not charge those modules above 80% capacity of around 23.8, (they will last longer and gives one a wider margin of error in case of mishaps) but 24.6 should be perfectly fine for near-full capacity.
