SUNNIVA 1000 W bifacial kit with a DEYE 800 W inverter review
A 1000 Wp bifacial balcony kit with a DEYE 800 W micro-inverter limited to the German 800 W ceiling, supplied with cables but explicitly without mounting hardware.
The bottom line A serious kit with named components and an unusually honest line about what is not in the box. It is sold entirely against one country’s rules, offers no monitoring, and never says which socket it expects.
A 1000 Wp bifacial kit with a named inverter and no brackets.
The sentence that prevents a bad morning
The fifth bullet states that no mounting hardware is included, and gives the reason: railings, facades, roofs and gardens all need different fixings. Two other kits in this family leave that to be discovered on delivery.
The components, named
Two 500 Wp bifacial glass-glass N-type modules and a DEYE 800 W micro-inverter with integrated grid protection, plus a 5 m connection cable and four 1 m solar leads. Naming the inverter maker means its grid standards can be looked up.
The rule it is built around
The third bullet cites the German Solarpaket 1 and the 800 W ceiling. That is a German rule. This site is read in five countries, and the ceiling, the registration duty and even whether plug-in connection is permitted differ between them. The product limit is real; the permission is local.
What is missing
Any monitoring. Every other kit here offers an application; this one describes none. And the socket type, which is the first thing a national rule specifies.

What it gets right, and what it leaves out

The absence of mounting hardware is stated outright rather than discovered on delivery
The inverter is named by maker and model class, not left as “a micro-inverter”
Integrated grid protection is named, which is what a grid code requires
Compromises
The 800 W cap is a German rule presented as a product characteristic
No monitoring at all, which every other kit in this family offers
The socket type is never named

Questions owners ask about this one
What is NA protection?
Grid and system protection: the function that disconnects an inverter when the mains voltage or frequency leaves its permitted range. It is required by grid codes, and naming it is a statement about compliance rather than about performance.
Does the 800 W limit apply outside Germany?
Not automatically. It comes from a German legislative package named in the third bullet. Other countries set their own ceilings, some lower, and a few do not permit plug-in connection at all. The rule where you live is the one that applies.
