battery breaker.
7) After 2 minutes, the bypass indicator LED goes green, and the load is powered
through maintenance bypass and static bypass.
8) Turn off the maintenance bypass breaker.
9) After 30S, the rectifier starts, the rectifier indicator LED goes green, and then inverter
starts.
10) After 60S, the system transfers to Normal mode.
6.4 Battery setting
The setting of battery needs to be done after the first time of powering off or any changes
done on the batteries.
The battery configure ration can be done through the LCD control panel (Figure6-1).
Figure 6-1 Configuration through LCD control panel
Setting of Battery Type
The battery type can be only set through the monitoring software. The system at
present supports lead acid battery and Lithium iron phosphate battery (LFPB).
Setting of Battery Number
1) Setting battery number for Lead- Acid battery
The nominal voltage of one block battery is 12V and for each block of battery, it
consists of 6 cells (each cell of 2V).For the setting, as is shown in Figure5-1, if the
battery is 40, it means that there are 40 blocks of batteries and both the positive and
negative are 20 blocks of batteries.
In the case of cell battery of 2V (usually with large capacity) is used, battery number
should be the same as the block battery. The cell battery actually in use should be 240
cells (6*40), with both and positive and negative of 120 cells.
The battery number setting range is 36-44
2) Setting battery number for LFPB
For the cell of each LFPB, the cell voltage is 3.2V; each battery block consists of 1 cell.
In total, if 40 blocks of Lead- Acid battery are used, for the LFPB, the number will be
150. Both the positive and negative are 75 cells.
The battery number setting range is 140-180.The lowest EOD voltage for the LFPB will
be 360V and highest voltage can be 620V.
