Note
Generally you do not need to set the management value. The defaults will do.
2. The charging management parameter value description is listed below:
Table 1.1 Charging management parameter value description
Parameter
Range
Default
Value description
Float
42V ~ 58V
53.5V
In the FC state, all rectifiers output
voltage according to the set “Float”
The “Boost” must be higher
than the “Float”
Boost
56.4V
In the BC state, all rectifiers output
voltage according to the set “Boost”
Limit (current limit)
0.1 ~ 0.25C
10
0.1C
10
When the monitoring module detects that the battery charging current
is higher than the “Limit”, it will control the current of the rectifiers,
through which it can limit the battery charging current.
C
10
is the battery rated capacity, generally set to 10 ~ 20% of the rated
capacity of one battery string
Over (over current point)
0.3C
10
~ 1.0C
10
0.300C
10
When the monitoring module detects that the battery charging current
is higher than the “Over”, it will raise the battery charge over-current
alarm
Automatic Boost
Yes, No
Y
Select “Y”, and BC will be conducted when conditions allow
Cyclic Boost
Select “Y”, and the monitoring module will control the system to enter
the Cyclic Boost when the FC time reaches the “Cyclic Boost Interval”.
The battery charging voltage is the preset “Boost”, and the time is the
preset “Cyclic Boost Time”
Cyclic Boost Interval
48 ~ 8760h
2400h
Cyclic Boost Time
30 ~ 2880min
720min
To Boost Current
0.050 ~
0.080C
10
0.06C
10
The monitoring module will control the system enter the BC state when
the battery capacity decreases to the value of “To Boost Capacity”, or
when the charge current reaches the “To Boost Current”. The charge
voltage will be the “Boost”
To Boost Capacity
10% ~ 99%
80%
Constant BC Current
0.002 ~ 0.02
C
10
0.01C
10
The system in the BC state will enter the FC state when the charge
current decreases to the “Constant BC Curr” and after the “Duration”.
The battery charge voltage then will be the “Float”
Duration (of constant BC)
30 ~ 1440min
180min
Boost Limit
60 ~ 2880min
1080min
To ensure safety, the monitoring module will forcefully control the
system to enter the FC state if during the BC state, the BC time
reaches the “Boost Limit”, or abnormalities occur (such as AC failure,
battery route faulty, and rectifier communication failure etc.)
