That depends entirely on where you live, what you rent or own, and what your grid operator requires. Registration duties, output limits, socket type and landlord consent are set locally, and no product listing can answer them for your address.
Balcony kits are sold across borders with identical boxes and very different legal treatment, so this is one page that deliberately refuses to give a number.
What varies by country
Whether a plug-in installation is permitted at all. Which socket type may be used. Whether the inverter must be limited to a stated output. Whether the installation must be registered with the grid operator, with a national register, or with both. Whether a qualified installer must be involved.
Every one of those has been different between neighbouring countries, and several have changed in recent years.
What varies by building
A tenancy agreement, an owners’ association, a listed facade or a shared balcony can each impose conditions that have nothing to do with electricity. Fixing anything to a railing also raises a structural question that the kit’s mounting instructions address only for the mount itself.
What the product does settle
The inverter names the grid standards it was assessed against, and the mounting hardware states what it is rated to hold and in what wind conditions. Those are the maker’s statements, and this site reports them as such.
Rule first, then kit
Find the local rule first, then the kit that satisfies it. Done the other way round, the common outcome is a working kit that cannot legally be plugged in — and an inverter output limit that cannot be changed after the fact.
Where this page and the manufacturer’s documentation differ, the documentation is the one to follow. Every capacity, output, input window, current limit, cycle count and temperature threshold on this page comes from the maker’s own published figures, with the unit as printed and the source named. None of it is measured here, and no figure is converted into another convention, because a converted number is a different number. And the limit this page does not cross: no cable size, fuse rating, earthing arrangement or mounting described here makes an installation safe. The page reports what a maker specifies for its own product — an input protection device, a clearance, a grid standard it names — and what applies to your installation is decided by the regulations in force where you live and by whoever is qualified to work to them.
What people ask before they order
What does the maker’s documentation settle?
The product side: the inverter’s compliance with the grid standards it names, its output limit, and the mounting and fixing instructions. It does not settle whether you may connect it where you live.
Who decides if a plug-in connection is allowed?
The rules of the grid operator and the national electrical regulations, which differ between countries and change. They are the reference, not a retailer’s listing.
