Charging current
/
When using only one GL48100, we recommend a charging current
of 50A, with a maximum current of less than 70A, to prevent battery
life reduction due to high current in low-temperature situations.
When using multiple battery systems in parallel, please set the
charging current = 50A × GL48100 quantity, but the maxium
charging current should < 200A,
With proper communication between the inverter and GL48100,
GL48100 BMS calculates and reports its discharging current based
on factors like temperature, SOC, SOH, and the number of paralleled
batteries. This allows the inverter to optimize output power while
prolonging the whole system's cycle life.
Discharing current
/
For some inverters, it's necessary to set the "Rated discharging
current." Please set this parameter to 100A.
•When using multiple GL48100s in parallel, please set the max
continuous discharging current to 100A xGL48100 quantity, but
keep the total discharging current below 200A.
With proper communication between the inverter and GL48100,
GL48100 BMS calculates and reports its discharging current based

prolonging the whole system's cycle life.
A note about discharging cut-off voltage:
The discharging cut-off voltage comes into play when communication between the inverter and GL48100 is lost or
when operating in the inverter's voltage-cut-off mode. Battery voltage can be affected by factors such as heavy load
output, low temperatures, and battery aging. These natural characteristics may lead to the inverter stopping
prematurely, affecting user experience.
When the load power is high or the ambient temperature is low, the battery voltage will reach the discharge cut-off
voltage prematurely (equivalent to a higher discharge cut-off voltage setting), causing the inverter to stop working
and resulting in less discharged energy, affecting user experience. When the load power is low or the ambient
temperature is appropriate, the battery voltage will slowly reach the discharge cut-off voltage (equivalent to a lower
discharge cut-off voltage setting), leading to an increased depth of discharge, and even over-discharging the
battery, which is detrimental to the battery's cycle life.
Therefore, it is challenging to appropriately manage the battery discharge state using the discharge cut-off voltage.
As a result, we recommend users set their inverters to battery SOC to manage GL48100 .
