User-Defined 2
This US2 setting is designed for the inverter to work with lithium battery without communication via BMS.
As floating charging is not required for lithium batteries, in US2 mode, the program 19&20 will be
interlocked and set to the same value whenever one of them is changed.
Compared with USE, the charger in US2 will immediately reduce charging current when the preset voltage
in 19 is reached.
NOTE: The US2 will not optimally charge the lithium battery due to the lack of BMS communication. The
battery capacity icon bar doesn’t reflect the actual battery capacity; it is converted from battery voltage. For
more details, please refer to page 13.
When the inverter is in US2, it could not correctly display the accurate SOC of the lithium batteries.
The displayed SOC is converted from battery voltage. The SOC will change only when the battery voltage
changes big enough.
Due to the ripple current from the utility charger, when “US2” is set for charging lithium batteries, it is
recommended to set the max utility charging current at 30% of the nominal charge current.
05: LI
Lithium
This setting only works when inverter communicates with lithium battery BMS built with the same protocol.
The program is set to “LI”, the LCD will show a hidden program of 36 about BMS protocol types.
There are many lithium battery BMS communication protocols, L01, L02 to L99.
For Sigineer Power LFP power walls, the protocol is L01.
When the battery type set as “LI”, the maximum charge current can be modified by the user.
Note: When the communication fails, the inverter will cut off output.
RS485 communication protocol is L01 to L50.
The CAN communication protocol is L51 to L99.
Program 06: Automatic Overload Restart
06: LFd
Disabled.
06: LFE
When this feature is enabled, the inverter will attempt to restart 3 times after overloads, if it still fails to start
the load after 3 attempts, it will show warning code 07.
Program 07: Automatic OverTemp Restart
Program 08: AC Output Voltage
The AC output voltage between hot and neutral can be set to 208V, 220V, 230V and 240V for MS6048D.
Program 09: AC Output Frequency
The AC Output Frequency can be set to 50Hz or 60Hz.
Program 10: Number of 12V Batteries Connected In Series
The default value is 4. This program is only a reminder about the 12V battery quantity.
Program 11: Maximum Utility Charging Current
