Wiring
Recommended wire thickness

For DC and AC input / output connecting wire, the thickness of the wire is very important. It is recommended to have 1 mm2 cross-sectional area of copper wire for every 5A of current.

For example, the appropriate wire cross-sectional area for a 5000W/48VDC load is calculated as follows:

Diameter can then be derived from A = π*r2
Consult a verified Wire Gauge and Current Limit table for guidelines. Failure to understand and adhere to these guidelines can result in wire and equipment damage and/or dangerously high temperatures.

Instructions for solar charging
Technical requirement for the external solar charge controller:
Rated Voltage: 48V DC
Rated Current: 5 ~ 50 A
Charging Voltage: 49.8V
Floating charge Voltage 50.4V
Note: Make sure the charging voltages and polarities of the battery and solar panels are correct.

Instructions for connecting with EXP unit.
VERY IMPORTANT: All the paralleled battery packs must be exact same spec. Wrong battery may damage the whole system.
Follow the below steps to connect the EXB-4500 to MPS3K unit.

1. Make sure the battery level of EXB-4500 and MPS3K-4500 are same. (Do NOT connect if the voltage difference more than 3V.)
2. Power OFF the MPS3K-4500, turn OFF the BMS and flip all the breakers OFF
3. Coding the battery pack. (Refer to 2.4.2)
4. Plug in the communication cable.(Refer to the Pic 2.4-1)
5. Plug in the battery power cable. (Refer to the Pic 2.4-1)
6. Flip all the Battery Breakers ON for both MPS3K and EXB-4500.
7. Press and hold the BMS “Reset” button for 1 second to turn on the BMS for both MPS3K and EXB-4500.
8. Power ON the MPS3K-4500 unit.

Note : It’s not recommended to reconnect the expansion battery frequently. Keep the EXB-4500 battery breaker ON when it’s connected to MPS3K to maintain the same battery level.

Reset BMS.
Wrong operation may cause the BMS protection.
To reset BMS, press and hold “Reset” button for about 7 seconds, release it when all the LED lights on. The BMS has been reset successfully.
Battery packs communicate address coding.

1. Coding the battery packs address before connection. The first battery pack address for “1”, the second battery pack address for “2”, the third battery pack address for “3” and so on.
2. Address coding instructions.

Instructions for AC Charger
Technical requirement for the external AC-DC charger:
Charger Type: 120VAC to 48VDC
Rated Current: 5 ~ 50 A
Charging Voltage: 49.8V
Floating charge Voltage 50.4V
Note: Make sure the charging voltages and polarities of the battery and connectors are correct.

Instructions for 12VDC Charger
You may charge the unit with a vehicle cigarette lighter power when the engine is running.
Technical requirement for the external DC-DC charger:
Charger Type: 12VDC to 48VDC charger
Rated Current: 2 ~ 20 A
Charging Voltage: 49.8V
Floating charge Voltage 50.4V
Note: Make sure the charging voltages and polarities of the battery and connectors are correct.

Outputs
DC outputs
5VDC loads are connected to the “5VDC Output” (USB sockets) ⑩ on the front panel. USB2.0 is rated for 2.4A, USB3.0 is rated for 3A, Type-C is rated for 12A.
12VDC loads are connected to the “12VDC Output” ⑨/⑫ on the front panel. The cigarette lighter socket is rated for 12V20A. The 5mm socket is rated for 12V2A each.
Make sure the positive (+) and negative (-) cables of your DC loads are wired correctly before plugging in. DC output short circuit may damage the unit.

Maintenance

• The EXB-4500 requires very little maintenance. The most important maintenance practice is to follow basic rules of battery charging. This will ensure good battery health.
• Under normal operating conditions, the battery will work well for 6-8 years or longer. If operating conditions are subpar, the battery may need to be replaced earlier than 6-8 years. Battery replacement MUST be carried out by qualified personnel. Individual batteries within the battery pack must not be individually replaced. The entire battery pack must be replaced according to the battery supplier’s instructions.
• When in storage or during periods of inactivity, the battery should be kept at 50% charge. At least once every 4-6 months, the battery should be fully charged to 100% capacity and then fully depleted to 10% capacity. In a high temperature region (>100 degrees F or >38 degrees C), this charge/depletion operation should be done every 2 months.
• Before replacing the battery, turn off the device, disconnect it from any power sources, and turn off the battery breaker. Remove any metal from your body (rings, watches, etc.). Use only tools with insulated handles. Do not put any tools or other metal objects on the battery pack.
• When connecting the battery cable, it is normal for small sparks to appear. These sparks are harmless. Do not shorten any battery connections or reverse positive/negative polarity.
