Balcony kits, panels and micro-inverters

Panels, kits and the inverter that turns one into the other.

The three pieces of a balcony installation

A module. A micro-inverter, which converts that module’s output to mains alternating current at the panel rather than in a cupboard. And a kit that packages both.

Why micro-inverters changed balcony solar

One inverter per panel means a shaded module drops only its own output instead of dragging a whole string down. It also means the high-voltage direct current run disappears, which is what made plug-in installations feasible at all.

Reading the micro-inverter page

The figures that matter are the input window, the output ceiling and the grid standard it conforms to. The individual page marks which of those the listing published.

A note on the maker name

The inverter carried in this range is a Hoymiles unit, and the page names it as such. Where the seller name and the manufacturer differ, this catalogue follows the manufacturer.
