One inverter per panel, and one shaded panel stops costing the others · review
An 800 W APsystems micro-inverter and the only one in this family to publish its input window: 28 to 45 V at the maximum power point, 16 to 60 V operating, 60 V maximum.
The bottom line The only micro-inverter on this shelf whose panels can be chosen on paper: four input figures published, a named certification and an integrated relay. It omits the enclosure rating that six of its seven neighbours publish.
An 800 W micro-inverter with the specification sheet the rest of this family does not have.
MPPT voltage range 28 to 45 V. Operating range 16 to 60 V. Maximum input voltage 60 V. Maximum input current 2 × 20 A. With those, a panel’s open-circuit voltage and maximum power voltage can be checked against the inverter before either is bought — including for the cold morning when open-circuit voltage is at its highest.
Six other micro-inverters in this family publish a wattage and nothing else.
VDE certified, with an integrated VDE relay named in the third bullet. Naming the relay is different from claiming compliance: it identifies the component that performs the disconnection.
WiFi and Bluetooth both integrated. Bluetooth matters where a balcony is out of range of a household network, which is common enough to be worth the line.
The ingress rating. Every other micro-inverter here except the EcoFlow publishes IP67, and this one publishes nothing about its housing. And no warranty.
German, French, Italian and Spanish Amazon stores quoted 126 € to 171 € when this page was compiled.
British Amazon catalogue carries an entry for it, with nobody selling.
American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

Because open-circuit voltage rises as cells get colder, and a string that sits comfortably under 60 V in August can exceed it on a clear January morning. The maximum input is what that cold-case calculation is checked against, and this is the only micro-inverter here that publishes one.
It is where the tracker can actually find a maximum power point. A panel whose operating voltage falls outside it will still connect — the operating range runs 16 to 60 V — but the tracking will be less effective. Publishing both ranges separately is what makes a panel match checkable.
800 W · 2 independent MPPT at 400 W each · limits not published · 2 MPPT · VDE and EMC certified · app monitoring · IP67 · warranty not stated
An 800 W grid-tied micro-inverter with two 400 W MPPT channels, VDE and EMC certification, lightning protection and an 800 V supercapacitor, at a stated 96 % conversion efficiency.
Best for: A two-panel installation where each panel is around 400 W and the per-channel limit is the deciding figure.
800 W · 2 MPPT inputs · limits not published · MPPT efficiency 99.8 %, peak 96.5 % · grid standard not named · monitoring not described · IP67 · MC4 plug and play
An 800 W micro-inverter with two independent MPPT channels quoted at 99.8 % tracking efficiency and 96.5 % peak conversion, with MC4 connectors and IP67 protection.
Best for: A straightforward two-panel balcony where monitoring is not wanted and MC4 is what the panels have.
