Installation

• Do not connect the pack to inverter conductors or Photo-Voltaic conductors. This will damage the battery and may result in an explosion.
• After unpacking, please check the product for damages and missing parts.
• Make sure that the inverter and battery are completely turned off before commencing installation.
• Do not interchange the positive and negative terminals of the battery.
• Ensure that there is no short circuit of the terminals or with any external device.
• Do not exceed the battery voltage rating of the inverter.
• Do not connect the battery to any incompatible inverter.
• Do not connect different battery types.
• Please ensure that all the batteries are grounded properly.
• Do not open the battery to repair or disassemble. Only the manufacturer is allowed to carry out any such repairs.
• In case of fire, use only a dry powder fire extinguisher. Liquid extinguishers should not be used.
• Install the batteries only inside the approved manufacturer enclosure. Installing the battery anywhere outside is strictly forbidden.
• Do not install the battery near water sources or places where the battery can get wet.
• Install the battery away from children or pets.
• Do not use the battery in a high static environment where the protection device might be damaged.
• Do not install with other batteries or cells.
• Please ensure the new batteries mounted on-site comply with the warranty scope or have ever been re-charged within 6 months; on top of that, please make sure the SOC of the present battery system onsite is 50%±5%.

Response to Emergency Situations
The battery can be used in single or multi in parallel. It is designed to prevent hazards or failures. However, the manufacturer cannot guarantee their absolute safety. Under exposure to the internal materials of the battery, the following recommendations should be carried out by the user.

• If there has been inhalation, please leave the contaminated area immediately and seek medical attention.
• If there has been contact with the eyes, rinse the eyes with running water for 15 minutes and seek medical attention immediately.
• If there has been contact with the skin, wash the contact area with soap thoroughly and seek medical attention immediately.
• If there has been ingestion, induce vomiting and seek medical attention.

Fire Situation
In situations where the battery is on fire, if it is safe to do so, disconnect the battery pack by turning off the switch to shut off the power to the system (External, if any). Use an FM-200 or Co2 fire extinguisher for the battery and an ABC fire extinguisher for the other parts of the system. Under any fire situation, please evacuate the people from the building immediately before trying to extinguish it.

Water Situation
The battery modules are not water resistant. Hence care should be taken not to get it wet. If you find the battery completely or partially submerged in water do not try to open it. Contact authorized personnel or manufacturers for further instructions.

Product Information
EP5 photovoltaic energy storage system is a high-voltage energy storage system based on a lithium-ion ferrous phosphate battery. It is equipped with a customized battery management system (BMS), which is designed for energy storage applications of household photovoltaic power generation users. In the daytime, the surplus power of photovoltaic power generation can be stored in the battery. At night or when necessary, the stored energy can be provided to the electrical equipment, it can improve the use efficiency of photovoltaic power generation, peak-load shifting, and provide emergency standby power.

• The battery system contains the following Interface to allow it to connect and operate efficiently.

Battery interface: 

• Handle
• Ground Terminal
• PCS COM
• BMS Status LED
• SOC LED
• DC+
• DC-
• Power Switch
• Valves
• LINK OUT
• Ground Terminal

Note:
Make sure that the battery pack is always exposed to the ambient air. The battery pack is cooled by natural convection. If the battery pack is entirely or partially covered or shielded, it may cause the battery pack to stop operating.

Exclusion
The warranty shall not cover the defects caused by normal wear and tear, inadequate maintenance, handling, storage faulty repair, modifications to the battery or pack by a third party other than the manufacturer or manufacturer agent, failure to observe the product specification provided herein or improper use or installation, including but not limited to the following.

• Damage during transport or storage.
• Incorrect Installation of battery into pack or maintenance.
• Use of battepackage ankan in an inappropriate environment.
• Improper, inadequate, or incorrect charge, discharge, or production circuit other than stipulated herein.
• Incorrect use or inappropriate use.
• Insufficient ventilation.
• Ignoring applicable safety warnings and instructions.
• Altering or attempted repairs y unauthorized personnel.
• In case of force majeure (ex: lightning, storm, flood, fire, earthquake, etc.).
• There are no warranties implied or express other than those stipulated herein. the manufacturer shall not be liable for any consequential or indirect damages arising or in connection with the product specification, battery, or pack.

Troubleshooting and Maintenance

1. It is recommended that the battery storage time is not more than 6 months.
2. Regularly check whether the service environment of the battery meets the requirements, and the installation position should be far away from the heat source.
3. The battery module should be stored in an environment with a temperature range between 0℃ -+35℃, and charged regularly according to the table below with no more than 0.5 C(A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity.) to the SOC of50% after a long time of storage.

Troubleshooting
When the S LED on the panel is flashing or normally on, it does not mean that the battery is abnormal, it may be just an alarm or protection. Please check the “Fault status indicated by indicator” in Chapter 7 for the detailed faulty definition before any troubleshooting steps. In general, the alarm indication is normal without manual intervention. When the alarm-triggering state is removed, the battery will automatically return to normal use.

Problem determination based on the following points

1. Whether the green light on the power switch is on;
2. Whether the battery system can be communicated with inverter;
3. Whether the battery can be output voltage or not.

Preliminary determination steps

The battery system cannot work, When the DC Switch is turned on and the Power Switch is pressed, the LED doesn’t light up or flash, please consider contacting the local distributor.

1. The LED display of BMS is normal, but it cannot charge and discharge. Observe the display screen of the inverter and there is no SOC. Please check whether the communication between BMS and to inverter is well connected. If the connection is good, please replace the communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor.
2. After the battery system is powered on, if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.
