Notice:
1. This product can be charged directly by the wall socket; please do not use
extension cords and cable taps.
2. When our product is charging, please do not plug other products in the same
socket. The current will be too high to bring damage to the cable and dire
risk. In a general household, when the same wiring exceeds 2200W, it will
activate the safety circuit breaker.
3. If the ambient temperature is too high or in the process of continuous
charging and discharging, the device may reach the set protection temperature
to enter the 2000W constant power output mode or enter the protection
mode due to the high temperature of the battery core, and then the normal
mode can be set when the temperature of the device is lowered.

(included in the accessory)
CAR CHARGER CHARGING
Please use the car charger (12V) that we provided to charge this unit, and car
charging is usually low power of 90-120W, so the charging time will be long.
Charging time for 12V car charger is about 9-10 hours.
Charging time for 24V car charger is about 4.5-5.5 hours.
If you need a quick charge, it is recommended to use the AC adapter.

EPS Function
This product has the bypass mode, does not need to pass through the
battery, can directly output from the AC.
In EPS mode, when the AC input power of the mains is cut off due to a power
outage, the ac input power of the mains can be used in about automatic
switch to the product battery within 20 ms to ensure AC output.
EPS Connections
As shown in the figure below, connect the product between the socket on the
wall and the electrical appliances, and the power of the product is in the ON
state. When you turn on the power of the electrical appliances, it will directly
use the AC power of the power grid.
In this state, when the power grid is cut off, it will automatically switch to the
product’s internal battery to supply power.
※In EPS mode, when charging and discharging at the same time, AC is
straight through output, while charging power < 1200W；AC charging +AC
discharge total power ≤ 1920W.

OPERATING INSTRUCTIONS
Power Output Attention
Press output switch to select the desired outlet type. The output port must press
the corresponding button to activate the port. When activated, the LCD display
will turn on and provide detailed information about the charging output. When
no output is activated, the LCD screen will automatically turn off.
Cooling Fan
The equipment is designed with an internal cooling fan to ensure that the
product runs within the proper temperature range. When the device experiences
a high output load, it will automatically turn on the fan. During discharging and
charging, the fan may run intermittently to keep the internal temperature within
the operating range. When the AC circuit is activated, the fan is likely to start to
ensure normal operation.
● Fan on condition
The cell temperature is greater than 55°C±5°C or the AC output power is
greater than 1000W or the inverter radiator temperature is greater than
90°C±5°C.
Overload Protection (Rated Power Mode)
Rated power 2200W, Load ≤ 2200W for long-term operation.
2.45KW < load ≤ 2.88KW, enter overload protection after 5-10 seconds;
2.88KW < load ≤ 3.6KW, enter overload protection after 1-5 seconds;
load > 3.6KW, immediately enter overload protection.
After the overload is released, press the button to restore normal output.
Constant Power Mode
Basically compatible with 99% load < 2000W resistive equipment;
Does not support constant power when AC charging;
When Load > 2.0KW, enter constant power 2000±50W;
When Output voltage=90V±5V and power > 2100W, shutdown after 5-10S.
Power Saving Sleep Mode (ECO Mode)
When the output power of the device is less than 5W, the device will go into
hibernation after more than 8 hours, and the input can be "awakened" when the
input is charged or any button is pressed. When not in use, press the switch
button to turn off the output.

INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS.
IMPORTANT SAFETY INSTRUCTIONS
1. WARNING – When using this product, basic precautions should always be
followed, including the following:
a) Read all the instructions before using the product.
b) To reduce the risk of injury, close supervision is necessary when the product
is used near children.
c) Do not put fingers or hands into the product.
d) Use of an attachment not recommended or sold by power pack manufacturer
may result in a risk of fire, electric shock, or injury to persons.
e) To reduce the risk of damage to the electric plug and cord, pull the plug rather
than the cord when disconnecting the power pack.
f) Do not use a battery pack or appliance that is damaged or modified.
Damaged or modified batteries may exhibit unpredictable behavior resulting in
fire, explosion, or risk of injury.
g) Do not operate the power pack with a damaged cord or plug, or a damaged
output cable.
h) Do not disassemble the power pack, take it to a qualified service person
when service or repair is required. Incorrect reassembly may result in a risk of
fire or electric shock.
i) To reduce the risk of electric shock, unplug the power pack from the outlet
before attempting any instructed servicing.
j) WARNING – RISK OF EXPLOSIVE GASES.
1) To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and manufacturer of any equipment you
intend to use in the vicinity of the battery. Review cautionary marking on these
products and on engines.
k) PERSONAL PRECAUTIONS
1) Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes.
NOTE
- 16 -
2) Wear complete eye protection and clothing protection. Avoid touching eyes
while working near the battery.
3) If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters the eye, immediately flood the eye with running cold water
for at least 10 minutes and get medical attention immediately.
4) NEVER smoke or allow a spark or flame in the vicinity of the battery or
engine.
5) Be extra cautious to reduce the risk of dropping a metal tool onto the battery.
It might spark or short-circuit battery or other electrical parts that may cause an
explosion.
l) When charging the internal battery, work in a well-ventilated area and do not
