2 Installation
2.1 Warning
Please read the manual carefully to get familiar with the installation steps before installation.
Be very careful when installing the batteries, especially flooded lead-acid batteries. Please wear eye
protection, and have fresh water available to rinse if any contact with battery acid.
Keep the battery away from any metal objects, which may cause a short circuit of the battery.
Loose connections and corroded wires may result in high heat that can melt wire insulation, burn
surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in motion.
Select the system connection cables according to the current density no higher than 5A/mm2.
(Following the National Electrical Code Article 690, NFPA70).
For outdoor installation, keep out of the direct sunshine and rain infiltration.
High voltage exists inside the inverter after turning off the switch. Do not open or touch the internal
devices and wait five minutes before conducting related operations.
Please do not install the inverter in humid, greasy, flammable, explosive, dust accumulative, or other
severe environments.
Prohibit reverse connection at the battery input end; otherwise, it will easily damage the equipment
or cause unpredictable danger.
Both utility input and AC output are of high voltage; please do not touch the wiring connection.
When the fan is working, please do not touch it to avoid injury.

IMPORTANT
The wire size is for reference only. Use thicker wires to lower the voltage drop and
improve the system performance when the distance between utility and inverter or
between inverter and batter is far.
The above wire size and circuit breaker size are for recommendation only. Please
choose a suitable wire and circuit breaker according to the practical situation.
2.3 Instructions
Installation steps:
Step1: Professional personnel read this manual carefully.
Step2: Determine the installation location and heat dissipation space.
Move the equipment: as the equipment is relatively large, it is recommended to use a forklift or crane;
if the ground is flat, it can be moved by wheels.
Place the equipment: As the equipment is heavy, it is recommended to be placed on flat ground, with
300mm space reserved all around, to ensure heat dissipation.
Fix the equipment: If the optional caster is chosen, rotate counterclockwise to fix and rotate clockwise
to move.
WARNING
Risk of explosion!
Never install the inverter with flooded batteries in a sealed enclosure! Do not install the
device in a confined area where battery gas can accumulate.

12
Step3: Takedown the junction box cover plate with special tools.
Step4: Wiring

13
Wiring order:
❶Ground——❷Battery——❸Utility——❹AC loads
WARNING
Never connect the utility to the inverter output; otherwise, the inverter may be damaged.
Grounding
The voltage of the whole system exceeds the safety voltage level. Thus reliable grounding is needed.
The grounding wire shall be the thicker wire no less than 35mm2) and shall be as short as possible. The
grounding point shall be as close as possible to the inverter.
CAUTION
When wiring, follow the order ❶❷❸❹ to connect the cables to the equipment, then
follow the order ❶❷❸❹ to connect ground, battery, utility, and load.
WARNING
Make sure all the wiring connections are reliable; otherwise, massive heat would
accumulate at the connection points to damage the terminals or even cause a fire.
Danger, high voltage! Terminals of the Utility input, AC output, and DC input produce high
voltage, do not close the breakers during wiring, and ensure each component's correct
polarity.

CAUTION
If the power is supplied to the different AC loads, it is suggested to turn on the loads
with a larger surge current till the load works well, then turn on the loads with a
smaller surge current. Especially for inductive loads, they should be turned on one by
one. Do not turn on the loads simultaneously to not cause excessive impact to the
inverter, to shorten its life span.
If the inverter is not in regular operation, or LCD or indicator displays abnormal, refer
to Section 5 to clear the fault or contact the after-sale service personnel of our
company.
Step12: Power off the equipment
1. Disconnect the AC load circuit breaker.
2. Long press the "AC output" button to turn off the inverter output.
3. Disconnect the bypass circuit breaker.
4. Disconnect the battery circuit breaker.
WARNING
As electricity exists in the capacitance, the LCD screen would be off after 30 seconds;
wait 5 minutes before opening the equipment to repair.
The inverter has a soft stat design and only takes effect when it starts. Do not
frequently switch the input circuit breaker when the inverter is incompletely powered
off. Otherwise, the input battery would undergo a high current impact. That is, the
input circuit breaker can be closed again after the LCD screen is off.
WARNING
After the inverter is disconnected from the utility and battery bank, you must wait 5
minutes before touching the internal conductive devices.
2.4 Output voltage/frequency grade switch
Operating steps:
Open the cover plate on the inverter right side and find the dial switches on the control board, located
on the top left corner; see the picture above. Set the output voltage/frequency according to demand,
then restart the inverter to take effect.
IMPORTANT
The factory default output voltage is 220VAC, and the output frequency is 50Hz.
The accessories can refer to the Packing List.
When the dial switch 1 is placed to the ON side, the output frequency is
60Hz, otherwise it is 50Hz,
When the dial switch 2 is placed to the ON side, the output voltage is
230VAC, otherwise it is 220VAC.
