Hi everyone, 

First Post here... I'm going to be setting up solar in a house I'm buying in the countryside. 

I got a cheap Axpert vm11 inverter and did what checking I could before buying, the main label seems legitimate, serial numbers look good, the little single phase mark looks good, the screws are all black, the manufacturer date label matches up with main label. 

I know it can be hooked upto a computer and check that way, but I don't yet have any batteries so can't turn the unit on, unless simply hooking up mains power means I can use the supplied software to check?

I was hoping if not maybe something under the cover like components used could be a giveaway? 

Thanks!

One way is if you can't open the cover without cutting a sticker with a year and month code on it (the smaller of two stickers). That sticker should cover one of the screws holding the cover on.

From your description, it does seem legitimate. I suppose you could post a photo of the larger sticker for someone like me to check. Black out the last several digits of the serial number if you want.

Hey thanks for the reply and tip on the sticker and screw, the sticker does cover the screw so that's good... 

Here's a photo of the sticker

I can't spot any flaws.
