If there's an unstable power supply due to lightning or other reasons, or if a high voltage
is detected at the AC terminal, the overload protection function (safety circuit breaker)
will activate. This safeguard disconnects the AC input port from external devices to
protect the product.
To restore the AC input function, follow these steps:
1. Turn off the main power button and disconnect all connected devices from the
ports.
2. After ensuring there are no abnormalities in any part, switch on the main power
button.
3. Press the overload protection button and reconnect the AC charge cable to
resume AC input.
14. AC Input
Recharge by connecting to a wall outlet or generator with the included AC charge cable
(Quick 1800W Max /Slow 600W Max). Ensure compatibility with utility power.

10
15. AC Quick / Slow Charge Switch
Adjust charging power by toggling between Quick and Slow charge modes. Ensure
compatibility before switching to Quick charge mode.
Note: When switching to the AC Quick charge mode, ensure that the power supply
device's output voltage ranges between 100V and 120V, and the output current exceeds
15A.
1. The charging power reaches 1800W when the power supply equipment's output
voltage is 120V, and the output current exceeds 15A.
2. Avoid using voltage ranges beyond 100-120V for charging the BP2000E power
station. Doing so might damage the product, and such damage is not covered by
the warranty.

The product's cooling fan operates automatically when reaching specific temperatures
during use. To maintain proper airflow, ensure the cooling air inlet/outlet remains
unobstructed, keeping objects at least 30cm away from these areas while using the
product.
The fan features three speed settings, activated based on internal temperature:
•Low-speed activates when the internal temperature reaches 45°C or higher.
•Medium-speed activates at temperatures of 55°C or higher.
•High-speed activates when the internal temperature exceeds 65°C.

Connection Guidelines
1. When the LCD screen displays , it signifies the BP2000E + B2000E connection is
correct. It can expand up to 7 B2000E batteries, indicating .
2. If the BP2000E + B2000E are incorrectly connected or plugged into the wrong
expansion ports, the BP2000E will issue a warning, and the icon will blink.
Note:When connecting the BP2000E with B2000E, if the remaining power is less than
5%, they cannot be paralleled due to a significant battery voltage gap. However, when
connecting to the input power source, you can successfully activate and recharge both
the BP2000E and B2000E.
Ordinarily, after connecting the BP2000E and B2000E, the device with higher battery
capacity will automatically charge the one with lower capacity. Nevertheless, if either
device's power is below 5%, the system will recognize the voltage disparity as too
substantial to establish a connection.

13
How to Expand the B2000E Expansion Battery Packs (E-
Combine)
•BP2000E can connect up to 7 B2000E expansion battery packs simultaneously,
expanding the capacity up to 16384Wh.
•For the specific connection method, please refer to the instruction manual of the
B2000E battery pack.
Connection Guidelines:
1. Prior to connecting the B2000E expansion battery, ensure both the BP2000E and
B2000E are powered off.
2. After connecting the B2000E expansion battery, ensure both the BP2000E and
B2000E screens display the parallel power icon before use.
3. Before connecting/disconnecting the B2000E expansion battery, turn off the
B2000E first.
4. Avoid touching the metal terminal of the wire with your
hands. Use a dry cloth to wipe it clean.
5. Ensure tight connections of the parallel wires to the
parallel ports of the BP2000E power station and
B2000E expansion battery. Incorrect connections may
generate heat at the terminals, impacting device usage
and potentially causing a fire hazard.
6. To charge the BP2000E+B2000E, connect the BP2000E
to the wall outlet/solar panel for charging. If the
B2000E expansion battery is separately connected to
the AC adapter/solar/car charger, disconnect the
B2000E before connecting it to the BP2000E.

14
BP2000E + B2000E Expansion Battery Pack
In this scenario, the input and output of the B2000E expansion battery will be disabled,
solely for capacity expansion.
1. Input: The B2000E expansion battery will not charge even when connected to the
AC adapter or Solar / car charging board.
2. Output: The 12V / 48V / USB output ports on the B2000E expansion battery will
also be unavailable.
Uninterruptible Power Supply (Ups)
To activate the UPS feature, first, connect your power station to a wall outlet using the
AC charge cable. Then, press the AC Switch and connect your devices through the AC
output ports.
1. Once you switch on the electrical device, it directly utilizes grid AC power.
2. In the event of a utility power outage, it seamlessly transitions to the internal
battery power of the product within 10 milliseconds.
While operating in UPS mode, the maximum AC output power is capped at 1400W. If the
AC output surpasses this limit, the UPS icon will blink, signaling an overcharge.
Simultaneously, the AC icon will turn off, and the output will be interrupted.

15
Solar Panel Recharging
Capable of receiving a maximum solar input of 1000W, with a maximum input voltage of
120V. Please note that solar panel charging effectiveness may vary due to weather,
climate, and other environmental conditions.
Exceeding the solar panel voltage limit of 120V may result in damage to the power
station. Such damages are not covered under the warranty.

16
Car Recharging
You can recharge this power station by linking it to a car's output port using the car
charge cable. Ensure that car recharging is carried out after starting the car engine. If the
car engine is not started, it might drain the car's battery. Typically, car recharging
operates at lower power, ranging between 90-240W (12V / 8A or 24V / 10A), resulting in
longer charging times. For faster charging, it's advisable to use a wall outlet.
Multicharge Recharging
This system facilitates rapid dual charging through simultaneous AC recharging and
Solar panel recharging. The combined maximum power output is 1500W from AC
charging and 1000W from Solar panel charging, totaling 2500W.

17
Estimated Usage Time Calculation
The estimated usage time (in hours) can be determined using the formula: 2048Wh ×
DOD × n ÷ (load W) = estimated usage time.
Note:
•DOD represents the battery's depth of discharge.
•'n' signifies the inverter's conversion rate. For a DOD of 90%, n = device.
•For a load with a power consumption (wattage) of 1000W, the estimated working
time is calculated as 2048Wh × 0.9 × 0.9 / 1000W = 1.6 hours (roughly calculated).
Please be aware that there exists electrical loss due to self-discharge when the output
port is active. The specific electrical loss for AC is 25W, DC24V is 3W, DC12V is 2W, and
USB is 0.5W.

Frequently Asked Questions (FAQ)
1. Why can't electrical appliances within the product's rated output power range be
used? The power station's battery is low and requires recharging. Additionally, some
appliances might demand higher peak power upon startup, surpassing the product's
power capabilities. Or, the nominal power of the appliance might exceed the
product's capacity.
2. Why is there noise when using it? The noise could originate from the fan or relay
upon startup or while in use.
3. Is it normal for the charging cable to heat up during use? Yes, it is. The charging cable
complies with national safety standards and has been certified.
4. What devices can the product support via the AC output? The AC output is rated at
2200W, suitable for powering most home appliances with a power rating lower than
2200W. Ensure that the total load through AC does not exceed 2200W before usage.
5. How do we determine the remaining discharge time? Check the LCD screen data; it
displays the remaining discharge time when turned on.
6. How can we confirm if the product is charging? During charging, the product screen
will display the input wattage, and the power percentage indicator will blink.
7. How should we clean the product? Use a dry, soft, clean cloth, or tissue to wipe the
product.
8. What's the storage procedure? Turn off the product and store it in a dry
environment, away from water. For long-term storage, we recommend using the
product every three months (completely deplete the remaining power and recharge
it to your desired percentage, such as 50%).
Maintenance Guidelines
1. It is advised to use or store this product within an environment ranging from 20°C to
30°C. Keep it away from water, heat sources, and metallic objects.
2. For safety precautions, avoid storing this product in environments exceeding 45°C or
dropping below -10°C for extended periods.
3. When not in use for an extended duration, charge the product to 60%. Prolonged
storage with a significantly depleted battery may cause irreparable damage and
reduce the product's lifespan.
