Multiplus 800 inverter settings ( DC input low shut down etc..)

Hello everybody.

Guys I am setting a Multiplus 800 connected to a 100 A Lithium battery with EXTERNAL BMS.

I have few questions about the default "inverter settings" that are the following .

Under the "Inverter tab" :

DC input low shut down=9,30 V

DC input low restart=10,90 V

DC input low pre-alarm 10,90 V

1# it seems to me this default setting is too low to protect the Lithium battery from a deep discharge > DC input low shut down=9,30 V > should I change it to a higher value like 11 V for example ? What do you recommend ?

2# the same for the other two values below . Are they too low ??!!

DC input low restart=10,90 V

DC input low pre-alarm 10,90 V


Thanks in advance for your help.

You have to look in the datasheet of your batteries.

Thanks Matthias , do I have to look at "End of discharge voltage" i.e 11,2 V and insert this voltage as DC Input low shutdown ?
