1.3.3 Bypass Mode

If the inverter overload capacity is exceeded under Normal mode, or if the inverter

becomes unavailable for any reason, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no interruption in power to the critical AC load. Should the inverter be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the load. This is to avoid large cross currents due to the paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms (60Hz). The action of transfer/re-transfer can also be done by the command through monitor.

direct sunlight and keep away from heat source. When installing, ensure the correct connection to the batteries with same specification.

2. Temperature. The most suitable storage temperature is 20 ºC to 25ºC.

3. Charging/discharging current. The best charging current for the lead-acid battery is

0.1C .The maximum current for the battery can not 0.3C.The suggested current is

0.05C-3C.

4. Charging voltage. In most of the time, the battery is in standby state. When the utility is

normal, the system will charge the battery in boost mode (Constant voltage with maximum limited) to full and then transfers to the state of float charge.

5. Discharge depth. Avoid deep discharging, which will greatly reduce the life time of the

battery. When the UPS runs in battery mode with light load or no load for a long time, it will cause the battery to deep discharge.

6. Check periodically. Observe if any abnormality of the battery ，measure if the voltage of

each battery are in balance. Discharge the battery periodically.

Fig.5-3 Configuration through monitoring software

5.4.1 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).

5.4.2 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 Fig.5-2, 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.

5.4.3 Battery Capacity Setting

Battery Capacity Setting sets the capacity value of the battery block .For example, if the system uses 40 blocks of 12V/100AH batteries, the Battery Capacity Setting should set to 100 Ah. If 240 cells of 2V/1000AH are used, the Battery Capacity Setting should be set to 1000 Ah. In case of there are more than one strings of battery in parallel, the battery capacity setting value will be the times of the single string. For instance, if the configuration is two strings of 40 blocks of 12V/100AH batteries, the battery capacity setting should be set to 200AH. The system sets current limits according to the battery capacity set. For the Lead-Acid battery, the current limit is 0.2C, and for the LIPB, the current is 0.3C. For instance, the 20-slot UPS is configured to 40 blocks of 12V/500AH batteries, which can provides total max charging current of 192A.Due to the current limits(0.2C) , the max charging current will be 100A(0.2*500A).

5.4.4 Float and Boost Charge Setting

In boos charging, the system charges the batteries with constant current. After the period, the system will enter the float charging. For the Lead-Acid battery ,the default float charge voltage per cell is 2.25V, boost charge voltage is 2.35V；

For the LFPB, the default float and boost charge voltage per cell is 3.45V

5.4.5 EOD Voltage Setting

The EOD voltage 0.6C is the EOD voltage when the discharging current is larger than 0.6C; EOD voltage 0.15C is the EOD voltage when the discharging current is less than 0.15C.EOD voltage decreases linearly as the EOD voltage Current increases from 0.15C to 0.6C, as shown in Fig.6-4.

Fig.5-4 EOD voltage

For Lead-Acid battery, the cell voltage is suggested to set to 1.65V/cell at 0.6C, and set to

1.75V at 0.15C

For the LFPB battery, the cell voltage is suggested to set to 2.7V/cell at both 0.6C and 0.15C.

5.4.6 Charging Current Percent Limit

This setting is for limiting the charging power, max current limit can be20% of the rated active power. The actual charging current is also limited to the battery capacity.

5.4.7 Battery Temperature Compensate

This is for setting the temperature compensate coefficient. Based on 25℃，when the temperature is higher than that, the discharging voltage goes lower; When the temperature is

lower than that, the discharging voltage goes higher.

5.4.8 Boost Charge Time Limit

This is for setting the Boost Charge time. When the set time is up, the system transfers to float charge. The setting range can be 1-48h.

5.4.9 Auto Boost Period

This is for setting the Auto boost period time. When the set time is up, the system boost charges the battery. It is suggested to boost charge the battery every three month, set the period to 4320h.

5.4.10 Auto maintenance Discharge Period

When the Auto maintenance Discharge period is reached, the system discharges the battery. This function should be enabled by checking the AutoMaint (RateSetting->SysCodeSetting1) through the monitoring software, as shown in Fig.5-5.
