When the battery type set to Li, the setting option 07 will change to display percent.
Note: When the battery type set as “Li”, the Maximum charge current can’t be modified by the
user. When the communication fail , the inverter will cut off output.
Inverter Connection
Some specific off grid inverters and this controller can communicate to summarize data. Make sure the inverter connect to the
controller Pin to Pin as below by communication port (“COM” port on the controller).
There will be 2 options to connect with inverter in Program 08. Set to mode CL1 if you select RS485 communication, set to CL2
if you select CAN communication. Details as below:
User-Defined
If “User-Defined” is selected, battery charge voltage and low DC cut-off voltage can be
set up in program 05,06 and 07.
User-Defined 2
Suitable for lithium battery when inverter not communicated with BMS.
If “US2” is selected, battery charge voltage and low DC cut-off voltage can be set up in
program 05,06 and 07.
Lithium
Only suitable for lithium battery when inverter communicated with BMS.
The lithium battery BMS communication protocol options:
……
Low DC cut-off SOC. If “Li” is selected
in program 2, this program can be set up.
Default 20%, 5%~50% Settable.
