Easun Igrid SV IV inverter - no output 

Brand new EASun inverter does not output any voltage.
Stay away from this company - there is no warranty!
Even if you buy if from Europe stock (www.easun-ener...) Paypal asks you to send the inverter to China after the dispute is finished in your favor. This costs almost as much as the inverter.
Update: after 5 months of initial purchase EASun sent a main board. I replaced it the next day and now the inverter works.
