HOW IT WORKS

Watch the energy move.

During daylight, panels make DC electricity and a microinverter converts it to AC. Your home uses that power first; the grid supplies the shortfall. At night, solar stops and the grid takes over.

THE NUMBERS, VISUALLY

Two ratings. One important difference.

Understand 800W

Maximum AC output800W / 800VA limit

Panel wattage and inverter output are not the same measurement. Exact kit limits still apply; values shown are labelled examples.

SOLAR FOR REAL HOMES

More than a balcony.

The right mounting depends on the exact product, structure and permissions.

GOOD STARTING POINT

Garden & ground mount

Flexible positioning, with wind-rated fixing or manufacturer-specified ballast.

STRUCTURE MATTERS

Sheds & small flat roofs

Useful space when the structure, waterproofing and access are suitable.

Explore

CHECK CAREFULLY

Balconies & terraces

Possible only with suitable mounting, permissions and clear escape routes.
