Finaly setting my solar tomorow need quick help!

[sale666]

Hey guys so finaly I got the time to setup my panels and inverter that I had for about 6-8 months sitting in the garage.. Tomorrow im setting it up and im going over the documentation to re-read steps..
And I came on this part (photo) for my onverter says AC side 600v?? Should it not be 220v (EU)? Why would I have 600v out of AC? This makes no sense or is that just tested max voltage since its the inspection report?

One thing I see is for off grid mode huawei says you need their backup box B0 and as far as I can see its nothing specials just fuses and breakers so I got my own will that not work is that breaker box equiped with something special? Any info on this would be great thanks!

I believe the 600v is the rating on the connector. Just like THHN wire (what they sell in the big box stores) is rated for 600v, and is used for 120/240v AC in the USA.

The number 4 box that indicates 600v and 30A appears to relate to your solar panel (PV) connectors. 10 gauge (6 mm2) is rated for 30 amps.

Thanks guys!
Seems I will need to buy their backup box too as it has some comunication port for it to work off grid (on purpose).
The thing is my DC fuse box came out 70€ while their backup box B0 thingy is 450+ € ffs...

Components 2 and 3 are MC4 connectors, those will be the PV input
Component 4 is listed as VAC as in voltage alternating current, this will be the AC input connector. I agree with DIYrich, the numbers are likely just the max rating for the connector.
