out by professional electrical maintenance personnel who are familiar
with the structure and operation of the device. Failure to follow this
precaution could result in bodily harm.
Do not connect this equipment to a consumer utility line box,
such as a home line.
Keep the inverter away from water, and avoid dropping water on the
machine or getting it up. Do not insert or pull the plug with wet hands.
Keep the inverter in a cool environment, suitable temperature should
be -20 ° C ~ 50 ° C, avoid direct sunlight and hot vents.
Keep the inverter away from flammable materials or where flammable
gases accumulate.
After prolonged use, the inverter will heat up, so avoid getting close to
heat sensitive substances.

COMMON FAULTS AND SOLUTIONS
USE ENVIRONMENT
WIRING REQUIREMENTS
2 meter long battery line configuration requirements.
Install the inverter according to local power requirements.
The installation location must be dry, clean and well ventilated.
Working temperature : ‐30°C to 60°C
Storage temperature : ‐10 to 40°C
Relative humidity : 0%‐90%, no condensation
Cooling: forced ventilation
Subject to outside interference
The inverter may be affected by some strong electromagnetic waves
in the use, such as nearby motors, power inverters, strong magnetic fields, etc.
Inverter indicator is not light
1. The battery and inverter are not connected and reconnected.
2. The pole of the battery is reversed and the fuse is blown. Replace the fuse.
Low output voltage
1. Overload, the load current exceeds the nominal current, and some of the load
is turned off to restart.
2. The input voltage is too low. Make sure the input voltage is within the nominal
voltage range.
Low voltage alarm
1. The battery is out of power and needs to be charged.
2. The battery voltage is too low or the contact is poor, recharge, check the battery
terminals or clean the terminals with a dry cloth.
Inverter has no output
1. The battery voltage is too low, recharge or replace the battery.
2. The load current is too high, and some of the load is turned off to restart the inverter.
3. Inverter over temperature protection. Allow the inverter to cool for a while and place
it in a well ventilated area.
4. The inverter failed to start and restarted.
5. The terminal is reversed, the fuse is blown, and the fuse is replaced.
