Value description 

Float  

53.5V 

In the FC state, all rectifiers output 

voltage according to the set “Float”   

Boost  

42V ~ 58V 

56.4V 

In the BC state, all rectifiers output 

voltage according to the set “Boost” 

The “Boost” must be 

higher than the “Float” 

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

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 

Select “Y”, and BC will be conducted when conditions allow   

Cyclic Boost 

Yes, No 

Y 

Cyclic Boost 

Interval 

48 ~ 8760h 

2400h 

Cyclic Boost Time  30 ~ 2880min 

720min 

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”   

To Boost Current    0.50 ~ 0.80C

10

 0.06C

10

 

To Boost 

Capacity 

0.1 ~ 0.95 

0.80 

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”.   

Constant BC Curr  0.02 ~ 0.99C10  0.01C

10

 

Duration (of 

constant BC) 

30 ~ 1440min    180min 

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”.   

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 and battery route faulty, etc.).
