1. Introduction

1.1 Important Safety Instructions

Danger!

- Please do not put the battery into water or fire, in case of explosion or any situation that might endanger your life.

- Please connect wires properly while installation, do not reverse connect. To avoid short circuit, please do not connect positive and negative poles with conductor on the same device.

- Please avoid any form of damage to battery, especially stab, hit, trample or s

Danger!

- Please shut off the power completely when removing the device or reconnecting during the daily use or it could cause the danger of electric shock.

- Please use dry powder extinguisher to put out the flame when encountering a fi hazard, liquid extinguisher could result in the risk of explosion.

- For your safety, please do not arbitrarily dismantle any component in any circumstances. The maintenance must be implemented by authorized technical personnel or our company's technical support. Device breakdown due to unauthorized operation will not be covered under warranty.

• Confirm that the maximum discharge current capability of the DC power interface of the user's photovoltaic power generation equipment, power supply or other power supply equipment should be higher than the maximum charging current of the products used in

Table 2-2.

If the maximum discharge capacity of the DC power interface of the user's photovoltaic power generation equipment is less than the maximum charging current of the products used in Table 2-2, the DC power interface of the user's photovoltaic power generation equipment shall have a current limiting function to ensure the normal operation of the user's equipment.

- Verify that the maximum operating current of the battery-powered user equipment (inverter DC input) should be less than the maximum discharge current of the products used in Table 2-2.

The security check

● Firefighting equipment should be provided near the product, such as portable dry powder fire extinguisher.
● Automatic fire fighting system shall be provided for the case where necessary.
● No flammable, explosive and other dangerous materials are placed beside the battery.

5.1.5 Unpacking inspection

6. Installation and Configuration

6.1 Battery system usage and operation instructions

After completing the electrical installation, follow these steps to start the battery system.

1. Open the BMS on/off, wait the screen open and show battery with normal status.
2. After the LCD screen show battery with normal status, open the air switch.

1. After pressing the power button, if the LCD screen show battery with ALM sta please refer to the "6.2 Alarm description and processing". If the failure cannot be eliminated, please contact the dealer timely.

2. Use a voltmeter to measure whether the voltage of the circuit breaker battery access terminal is higher than 48V^N , and check whether the voltage polarity is consistent with the inverter input polarity. If the circuit breaker battery input terminal has a voltage output and is greater than 48V^N , then the battery begun to work normally.

3. After confirming that the battery output voltage and polarity are correct, turn on the inverter, close the circuit breaker.
4. Check if the indicator of the inverter and battery connection (communication indicator and battery access status indicator) is normal. If it is normal, successfully complete the connection between the battery and the inverter. If the indicator light is abnormal, please refer to the inverter manual for the cause

6.2 Alarm description and processing

When protection mode is activated or system failure occurred, the alarm signal will be given through the system status on the LCD. The network management can query the specific alarm categories.

If the fault such as single cell over voltage, charging over-current, under-voltage protection, high-temp protection and other abnormalities which affects the output, please deal with it according to Table 6-1.

Table 6-1 Main alarm and Protection

Statue	Alarm category	system status	Processing
Charge state	Over-current	Over-current during slow charging	Stop charging and find out the cause of the trouble
	Over-voltage	Cell voltage too high in charge	Stop charging
	High temp	Temperature too high	Stop charging
	Low temp	Temperature too low	Stop charging
Discharge state	Over-current	Continuous over-current	Stop discharging
	High temp	Temperature too high	Stop discharging
	Low temp	Temperature too low	Stop discharging
	Low-voltage	Cell voltage too low in discharge	Stop discharging

6.3 Analysis and treatment of common faults

Analysis and treatment of common faults in the Table 6-2:

Table 6-2 Analysis and treatment of common faults

No.	Fault phenomenon	Reason analysis	Solution
1	The indicator does not respon after the power on Total voltage lower than 40V*N Check the total voltage	Total voltage lower than 40V*N	Check the total voltage
2	No DC output	Battery data status is abnormal. Battery gets into over-discharged protection	Read the battery information on the monitor.
3	The DC power supply time is too short	Battery capacity become smaller	Storage battery replacement or add more modules
4	The battery can't be fully charged to 100%	Charging voltage is too low	Adjust charging voltage at 57V*N
5	The power cable sparks once power on and ALM light RED	Power connection short-circuit	Turn off the battery, check the cause of th short circuit
6	Communication fault	The battery type of the inverter is wrong/Communication cable used incorrectly/The communication cable is incorrectly connected at the battery communication port or the inverter communication port/The battery firmware version is too low to support t inverter	Check these possible causes one by one

If you need any technical help or have any question, please contact the dealer in time.

7 Battery Module Storage

①To ensure the battery service life, the storage temperature shall be kept between 0°C\~35°C.
②The battery shall be cycled at least once every 6 months.

8 Maintenance

Warning! Improper decommissioning may cause damage to the equipment and/or battery inverter.

Before maintenance, ensure that OHS-100 is decommissioned according to relevant provisions.

Note: All maintenance work shall comply with local applicable regulations and standards.

The USB-CAN port of OHS has the functions of upgrading firmware and recording battery data, which can be used as an auxiliary tool.

To ensure safe operation, all plug connections must be checked. If necessary, relevant operators shall press them back into place at least once a year.

The following inspection or maintenance must be carried out once a year:

• General visual inspection
• Check all tightened electrical connections. Check the tightening torque according to the values in the following table. Loose connections must be retightened to the specified torque.

Connection mode	Tightening torque
high-voltage BMS box grounding	4.5Nm
Fixing the lug of the high-voltage BMS	1.2Nm
Fixing the lug of the battery module	1.2Nm

• Using the monitoring software, check whether the SoC, SoH, battery voltage and temperature of the battery module are abnormal.
• Shut down and restart OHS-100 once a year.

Note: If the system is installed in a polluted environment, maintenance and cleaning must be carried out at short intervals.

Note: Clean the battery rack with a dry-cleaning cloth. Ensure that no moisture comes into contact with the battery connections. Do not use solvents.
