5. Do not make or break connections while batteries are operating.

6. Ensure the battery and rack are properly grounded.

7. Use personal protective equipment (PPE) such as professional insulative equipment.

8. Inspect all existing wiring to ensure it meets specifications before use.

9. Keep children away from the battery and relevant systems.

10. The battery stops charging at 32F. If charging current is detected below this temperature, disconnect the battery immediately.


How should the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02 be stored?

Proper storage is critical for the health of the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02:

Battery State: EG4 recommends bringing each battery to a 50% State of Charge (SOC) before storage. Recharging is recommended after 8 – 9 months in prolonged storage.

Environmental Factors: For best results, store in a moderate temperature between 41F and 68F (5C and 20C). Avoid wet locations or high humidity (above 55%). Store away from combustible materials.

What tools and requirements are needed to install the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02?

Installation requirements for the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02 include:

Tools Needed: 10mm socket and ratchet, Phillips head screwdriver, Torque wrench, and M8-1.0 terminal bolts (included).

Cable Sizing: Use the included 4 AWG power cable only for connections to a battery rack busbar. If ambient temperature exceeds 86F (30C), cable size must be increased per NEC 310.

Series Warning: Do not put batteries in series; the BMS and internal components are not designed for it.

Orientation: Never position the battery upside down or face down. Horizontal orientation is best; vertical orientations on the side are acceptable.

Torque: Battery bolts require a torque of 60 in-lbs (6.8Nm). Improper tightening can lead to damage and void the warranty.


What is the proper startup and shutdown procedure for the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02?

To safely start the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02:

1. Close (turn on) the battery’s circuit breaker.

2. Wait approximately 5 seconds, then turn on the battery’s BMS via the power button.

To safely shut down the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02:

1. Power off the battery’s BMS via the power button.

2. Open (turn off) the battery’s circuit breaker.

Note: When using multiple batteries in parallel, repeat these steps for each battery, always starting with the master battery.


How are communications configured for multiple EG4 LIFEPOWER4 SR-48-100-LP4-IN-02 batteries in parallel?

For parallel communication setup with the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02:

1. Ensure all battery breakers and BMS are OFF.

2. Set a unique address code for each battery using the 6-pin DIP Switch ID Table. ID No. 1 is designated as the Host battery.

3. Use standard CAT5 cables to connect the Battery-Comm ports between batteries in a daisy-chain fashion.

4. Connect the Host battery (ID 1) to the system/inverter using the RS485 or CAN port.

5. Power on the batteries one at a time, beginning with the Host battery.


What are the protocol selection DIP switch settings for the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02?

The Protocol ID DIP switch settings for the EG4 LIFEPOWER4 SR-48-100-LP4-IN-02 depend on the inverter brand:

CodeBrandCommunications
1EG4/LuxCAN
2GrowattCAN
3Sol-ArkCAN
4DeyeCAN
5MegarevoCAN
6VictronCAN
7LuxpowerCAN
8SMACAN
