Duo 890W floor frame kit

Unpack it and you'll find

• 2 × 445W TOPCon N-type panels (bifacial, glass-glass)
• 1 × APsystems EZ1-M 800W microinverter
• UK-made ground mounting stand
• 4m AC connection cable and 2m DC extension cables

Ballast isn't included. You'll want blocks, not bricks: see below for how many.

Room for two

Two panels need a clear run of about 3.7m by 1.2m. Edwardian terraces in places like Levenshulme, Chorlton and Heaton Moor often have the longer yards that suit it.

It sits on the flags on its own feet, so nothing's fixed to the house or the yard wall. Keep a clear way to the back gate and the bins.

Ground only. Not for walls, roofs or balconies.

Holding it down when the wind gets up

Ballast isn't in the box. The maker asks for dense blocks of at least 18kg each: 2 for gusts over 40mph, 5 over 60mph and 10 over 80mph. Any builders' merchant sells them.

Tick these off first

• A level, sunny run of about 3.7m × 1.2m on the yard floor.
• A weatherproof outdoor socket within reach of the kit's 4m lead. Straight into the wall, no extension leads, reels or adaptors.
• Modern RCD protection in your fuse box. Old fuse box, or not sure? An electrician can check it, or fit the outdoor socket.
• Renting, leasehold or in a managed block? Get written permission from your landlord, freeholder or managing agent before you buy.
• Give your home insurer a quick ring before you set it up.
• Register it free at myplugin.solar before you switch on. That lets Electricity North West, who run the wires round here, know it's there.
• One kit per household, and never wired up with a home battery.

When it ships

Once the maker confirms a date, the kit goes on pre-order and the dispatch date shows here, in your basket and at checkout.

On a pre-order you pay in full when you order. If we can't dispatch by the long-stop date in your confirmation email, you choose: a full refund or keep waiting. You can cancel for a full refund at any time before dispatch, and for 14 days after delivery.
