Please refer to table 3-2
1. The voltage in above table is at 25
℃
. Please adjust the data according to table 3-3 at
other temperature.
2. Energy storage system can be off-grid power supply and grid power supply
according to real situation. The off-grid defined as tough power supply, to protect the
battery better, please set refer to above table or contact to manufacture.
3. Above are standard setup parameters in table 3-1. We suggest you to set up end
voltage (LVBD) based on different load current to make the battery life longer. Please
refer to table 3-2.
