Inverter can not open the machine:
① Battery voltage is too low or the battery is damaged, recharge the battery or replace the battery.
② The battery and the inverter wire is not connected, reconnect.
③ battery and inverter reverse polarity, the fuse blown, replace the appropriate fuse.

Inverter no output:
① Battery voltage is too low, re-charge the battery or replace the battery, check the wire is connected.
② input voltage is too high, according to the inverter rated input voltage to adjust the appropriate input voltage.
③ load power is greater than the nominal power inverter, the use of power less than the nominal power inverter.
④ inverter over-temperature protection, the inverter on the ventilated place for 15 minutes cooling time.
⑤ When using low-power electrical appliances, the inverter fails to start up. The peak power of the electrical appliances is greater than the peak power of the inverter, and the inverter with larger peak power is replaced.

Battery life is too short:
① electrical power consumption, replace the large capacity battery.
② bad or damaged battery, replace the battery.
③ battery charging is not enough, replace the battery or charge the battery.
④ wire attenuation voltage, shorten the wire length or use thicker wire.
