3. Inspection checkpoints

 

3.1

 Check procedure 

a)

 

Make sure inverter is same as you purchase. 

b)

 

Make sure inverter is in good condition which don’t get 
damaged during transportation; if damaged, please don’t 
connect with AC main power. 

c)

 

Make sure the S/N on warranty is same as inverter. 

 

Please inform our salesperson ASAP if you find the above problems.
