Range Default
In the FC state, all rectifiers output
53.5V
voltage according to the set "Float"
In the BC state, all rectifiers output
56.4V
voltage according to the set "Boost"
When the monitoring module detects that the battery charging
current is higher than the "Limit", it will control the current of the
0.1C rectifiers, through which it can limit the battery charging current.

Select "Y", and the monitoring module will control the system to
enter the Cyclic Boost when the FC time reaches the "Cyclic Boost

the time is the preset "Cyclic Boost Time"

10 10
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".
The system in the BC state will enter the FC state when the charge

current decreases to the "Constant BC Curr" and after the
180min
"Duration". The battery charge voltage then will be the "Float".
To ensure safety, the monitoring module will forcefully control the
system to enter the FC state if during the BC state, the BC time
1080min
reaches the "Boost Limit", or abnormalities occur (such as AC
failure and battery route faulty, etc.).
