A: 1. Secure the supplied negative (black) DC cable to the negative (-) bolt on the inverter and connect the other end to the negative (-) post of the battery.
PS: Make sure your battery capacity is large enough and the voltage is correct before connecting the inverter. Connecting the cables in reverse will damage the inverter and void the warranty.
A: Reason: The power switch is off or the inverter is in poor contact with the battery.
solutions: a. Press and hold the power switch for 1-2 seconds to turn on, the inverter switch is a long-press switch，b. Check the cables and make sure they are tightly connected.
A: 1. Reason: Low input DC voltage
A: A true RMS voltmeter is required to correctly measure the output correction wave inverter voltage. a. Test the output voltage with a true RMS meter, b. Try to keep the input voltage within the rated power range, c. Replace the battery of the meter, and then re-test.
A: Reasons: 1. The load power is too large, or the actual power of the electrical appliance exceeds the nominal power， 2. The starting power is greater than the rated power (especially for electrical appliances with motors)， 3. The battery is too small;
solutions: a. Reduce the load power, or Turn on the appliance first, then turn on the inverter, b. Choose a larger inverter, c. Replace a larger battery and make sure the battery is fully charged.
A: The main reason is that the instantaneous current is too large, which causes the detection voltage to be too low and triggers a low-voltage alarm.
Solution: Please restart the inverter several times.
A：This voltage has no meaning, zero line can be ground.This is normal, there is no current leakage.
