1. Connect GND for the batteries

2. Connect and tight the power cables of batteries to cabinet terminal or switching power supply.

(The battery gaps shall be more than 10mm.)

3. Connect the communication cables of batteries to computer

4. Switch on the battery switch.

ConnectionWhat is our product

Not Recommend

paralleling batteriesWhat is our product

OK, but not good Good choice


• Check the screws and other connection to ensure a reliable installation.

• Have a data read test for the batteries with software, and download the

information into the computer. If the displays passed, then we can know the

battery is well and the parameter settings are right.

• Please fill in related forms after installation and debugging, check and record

battery conditions. Ask the user to sign and confirm the records.

• Please turn off the switch of the batteries if main power is not connected.

• Please recharge the battery before put into use according to operation manual, or

it will do great harm to battery.

Maintenance

In order to assure service life, the batteries should be correctly inspected and maintained. Maintenance procedures are

recommended as follows:

1 Monthly Maintenance

— Keep the battery-room clean.

— Measure and record the ambient temperature of the battery-room.

— Check each battery’s cleanness; check damage and overheating trace of the terminal, container and lid.

— Measure and record the total voltage and current of the online battery system to make sure no abnormal system issue.

2 Quarterly Maintenance

— Repeat monthly inspection.

— Discharge battery and recharge battery to 80%SOC

— Measure and record voltage of individual cell during discharge

3 Yearly Maintenance

— Repeat quarterly maintenance and inspection.

— Check whether connectors are loose or not and tight them

— Make a discharge test to check with exact load, discharging 50% of rated capacity.

Maintenance in warehouseWhat is our product

54

1. Discharge test Periodicity

Optional every 3 months per once.

2. Rate of Discharge

Discharge current according to load power and discharge rate no more than 0.2C.

3. Depth of discharge

a) 50%DOD;

b) Discharge end voltage: 48V.

Maintenance for long floating batteryWhat is our product

1. Insufficient Charge

If charge voltage is not set correctly (lower than 3.8Vpc or 54.75V per 48V string), the battery system

will in an insufficient charge state, which may not impact battery service life, but may reduce battery

backup time as request.

2. Over Charge

If charge voltage is not set correctly (higher than 3.8Vpc individual or 54.75V per 48V string), the

battery system will be over charged, which may impact battery service life and even bring further safety

issue.

3. Too low or too high temperature

Too low temperature will affect the capacity of battery when discharge, and may destroy battery when

charge. While too high temperature will also cause problems, such as water loss, life decrease, thermal

runaway, deformation, etc.

Maintenance precautionsWhat is our product

Reasons:1. If communication failed and LED turn off which means BMS is not work, might be caused by B-/B+ cable or

sensor cable looseness;2. LED flashing but communication failed, might be used wrong PC software;3. LED flashing but communication failed, might be used wrong 485 to USB communication cable;4. LED flashing but communication failed, might be connection of 485 to USB communication cable is not well;5. LED flashing but communication failed, might be chosen wrong ADD channel;6. LED flashing but communication failed, might be 485 to USB communication cable broken.7. LED flashing but communication failed, might be BMS failed.

Solution:1. For reason a): Make sure B-/B+ cable and all sensor cables are connected well, if still looseness, please change

new cables;2. For reason b): Use right PC software;3. For reason c): Replace right 485 to USB communication cable;4. For reason d): Detect connection of 485 to USB communication cable, if still looseness, please change new

cables;5. For reason e): Choose right ADD channel;6. For reason f): Replace right 485 to USB communication cable;7. For reason g): Make sure U6 component is failed, if yes, return to the factory for repair.
