The surface of the inverter produce high temperature when it is working
，
please stay away from materials or equipment which affected by high
temperature
This inverter can only be used singly, parallel connection or in series will
damage the inverters.
It’s an off-grid inverter, if connect to the grid, the inverter may be
damaged.

Wiring
NOTE:
If the output is connect the different load, it is suggested
that the large shock current load is turn on firstly, then the small
shock current is turn off.
NOTE
：
Turn off the inverter, and then cut off the DC input power
supply when the load stops working.
WARNING
：
When the inverter polarity reversed, the fuse or
inverter will be damaged.
WARNING
：
Be careful the electric shock risk, the AC port will
output the high voltage.
WARNING
：
DO NOT open the product cover or where the
children can't reach to prevent electric shock.
WARNING
：
Please contact the professional, when the inverter
occur the faults

℃
or the internal temperature exceeds
65
℃
, the inverter will automatically cut
