3. Battery Power First (Solar charges the battery but grid AC Power is
only used if battery is almost empty).
● Dual-CPU Intelligent Control Technology manages energy input/output.
● Smart Fan Control keeps the unit cool, safe, and reliable.
● Low-frequency pure sine wave output is clean and reliable for any load.
● Wide input voltage range and consistent voltage output.
● LCD display shows real-time running statuses at-a-glance.
● Battery over-voltage and low-voltage protection, overload protection, short
circuit protection, over-temperature and under-temperature protection.
● Intelligent MPPT solar controller features over-charge & over-discharge
protection, current limiting charging, and multiple other safety protections.
2. Initial Inspection, Storage, Precautions
2.1 Initial Inspection
2.1.1 Ensure your box contains the following: MPS unit, AC Charging Cable,
DC Car Charging Cable, Solar Charging Cable, User Manual.

4. Wiring
4.1 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 mm2cross-sectional area of
copper wire for every 5A of current.
Area of wire
For example, the appropriate wire cross-sectional area for a 5000W/48VDC
load is calculated as follows:
Area of wire
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.

#
Working
mode
Description
01
The grid
priority
mode
(Default)
In working mode 01, the AC input directly powers the AC
output (through a voltage stabilizer), bypassing the
battery (a.k.a. “pass-through AC power”). When the
grid’s AC power is over-voltage, low-voltage, distorted
waveform, or cut off, the unit will draw from the battery
power supply. When the grid power returns to normal,
the unit will re-enable pass-through AC power.
02
Energy-
saving
mode
In working mode 02, the inverter only turns on when the
unit detects load power greater than 15% of the
inverter’s 3000W rated output. When it detects small or
no, i.e. when the total load power is less than 15% of the
inverter’s rated power, the inverter will remain off. This
ensures the lowest power consumption of the battery
bank by keeping the inverter shut off. Under this mode,
the unit measures load power every 15 seconds.
03
Battery
priority
mode
In working mode 03, the AC input does not charge the
battery or power the loads. The unit utilizes solar or DC
(car) power only; solar and DC charge the batteries and
supply power to the loads through the inverter. When
the battery meets the low-voltage protection point, i.e.
when the battery is 90% empty, the unit will enable
pass-through AC power if the grid power is available.
When the battery is fully charged again, the unit will
again only use solar or DC power.

4.3 Instructions for connecting Solar Power
Use the correct size of extension PV cable (4mm² or bigger). Make sure the
solar power voltage and wattage are within the allowed ranges
(60VDC-150VDC, Max. 1,500W). Plug solar charger cord into the "Solar
input connector" ⑮(see section 3). Make sure the positive (+) and negative
(-) cables are wired correctly; incorrect wiring may damage the unit. Turn on
the “Solar Input Breaker” ③.

breakers OFF.
3Coding the battery pack. (Refer to 4.4-2)
4Plug in the communication cable.(Refer to the Pic 4.4-1)
5Plug int the battery power cable. (Refer to the Pic 4.4-1)
6Flip all the Battery Breakers ON for both MPS3K and EXB-4500.
7Hold and press “Reset” button to turn on the BMS for both MPS3K
and EXB-4500.
8Power 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.

4.7 Outputs
4.7.1 AC outputs
120VAC loads are connected to the “AC Output” ①outlets on the front
panel. The total continuous power of all combined AC loads should be no
more than the inverter’s rated continuous power of 3,000 watts. Brief surges
up to 6,000 watts are acceptable. For a single outlet, the maximum
continuous amperage is 15A. For the TT-30R outlet ⑥, the max amperage
is 25A.
4.7.2 DC outputs
5VDC loads are connected to the “5VDC Output” (USB sockets) ⑩on 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” ⑧/⑨ 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.

5. Power ON
Note: Make sure voltages and polarities of external battery and
solar panels are correct (see section 8)
5.1 Inverter Power ON
5.1.1 Power On steps
Turn on the battery breaker. Press and hold BMS “Reset” button for 1
second to turn on the BMS (LED indicator Lights ON).Then long press the
"ON / OFF" button on the operation panel for 2 seconds; release it after the
beeper sound. The "INV" indicator light will turn on, indicating that the
inverter has started.
5.1.2 AC Input
Connect the “Line,” “Neutral,” and “Ground” AC cable ends to the
corresponding “AC Input Terminals.” Turn on the “AC Input Breaker.” Plug
the other end into a working power outlet. The "LINE" indicator light will turn
on, indicating the AC Input power is passing through to the AC Output.
5.2 Solar Charge Controller
Make sure the solar power voltage and wattage are within the allowed
ranges (see section 8). Wire solar panels via cables to the “Solar Input
Terminals,” making sure the (+) and (-) are correct. Turn on the “Solar Input
Breaker” (make sure the Battery Breaker is on first). When the solar panels
are exposed to sunlight, the "PV" indicator light will turn on, indicating that
the solar power is charging the batteries through the MPPT solar charge
controller.

5.3 Shutdown
To properly shutdown: Turn off all loads and all energy inputs. Long press
the "ON/OFF" button for 2 seconds, releasing after the internal relay action
produces an audible “click.” The AC output will turn off and the LCD screen
will turn off. Press and hold the BMS “Reset” button until the red light
flash,BMS OFF. Finally, turn off all the breakers in the proper order (see
directly below).
Caution: If the unit will be unused for a long time and neither solar
power nor an AC charger will be connected, please turn off the BMS to
avoid the battery deeply discharging.
5.4 Battery protection
While AC output is turned on, protective actions are executed if certain
battery voltages are measured.

5.6 Connecting an Electric Generator:
When connecting an electric generator, make sure to follow these
guidelines:
5.6.1 Make sure the generator output voltage is within the MPS unit’s AC
input range (see Section 8). To connect the generator, first turn off the AC
Input and Output breakers. Wire the generator’s output to the MPS unit’s AC
input terminals according to the instructions (see Section 4.5). Start the
generator and make sure it is running stably. Make sure there are no loads
connected to the MPS unit’s AC or DC outputs. Finally, start up the MPS
unit.
5.6.2 After the MPS unit is started, connect loads one-by-one to the MPS.
5.6.3 We suggest the electric generator’s power output capacity be 2-3
times that of the MPS (i.e. 6000 – 9000 watts).

6. Maintenance
6.1 The MPS-3K requires very little maintenance. The most important
maintenance practice is to follow basic rules of battery charging. This will
ensure good battery health.
6.2 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.
6.3 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.
6.4 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.
6.5 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.
