1. Product features
● Three programmable working modes prioritize different energy needs:
1. Grid Power First (a.k.a. “Pass-Through AC Power”)
2. Energy Saving (Inverter stays OFF unless load is detected)
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.
2.1.2 Make sure the equipment was not damaged during transit. If there is
any damage, DO NOT POWER ON. Report to product dealer and carrier.
2.2 Installation, storage, precautions
2.2.1 Installation should be performed by a qualified technician.

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.

4.4 Instructions for connecting Expansion Battery
VERY IMPORTANT: All the paralleled battery packs must be exact same
spec. Wrong battery may damage the whole system.
2.4.1 Follow the below steps to connect the EXB-4500 to MPS3K unit.
1Make sure the battery level of EXB-4500 and MPS3K-4500 are
same. (Do NOT connect if the voltage difference more than 3V.)
2Power OFF the MPS3K-4500, turn OFF the BMS and flip all the
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.

4.4.2 Battery packs communicating address coding.
(1) Coding the battery packs address before connection them. 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) Set the address for “0” if the MPS3K unit without expansion battery
pack.
