Where it can go

This kit sits on its stand on level ground, such as a lawn, patio or gravel area. It's a ground-mount kit only, so it isn't for walls, roofs or balconies. The maker's datasheet says it's not suitable for use on balconies.

Ballast isn't included. The maker's manual says to use dense concrete blocks of at least 18kg each, sitting on the stand's lower plates on both sides: 2 blocks where gusts can top 40mph, 5 above 60mph and 10 above 80mph. Keep cables on top of the blocks, never trapped under them, and keep blocks off the microinverter.

The kit plugs straight into a wall socket within reach of its 4m cable. The maker's datasheet says it's designed for a suitable outdoor socket fitted and certified by a qualified electrician. The maker's checklist asks for a weatherproof outdoor socket (at least IP55) within 4m of the kit. Never use an extension lead or adaptor.

Keep it away from a wall forming a boundary with a neighbouring property. Our plug-in solar rules list every place a kit can't go.

Before you order

Check each of these before you order. If you can't tick one, ask us first.

• About 3.7m × 1.2m of space that gets the sun.
• Plug straight into a suitable wall socket. No extension leads, cable reels or adaptors.
• Modern RCD protection in your fuse box. If you have an older fuse box, or you're not sure, have an electrician check it first.
• If you rent, own leasehold or live in a managed building, get written permission from your landlord, freeholder or managing agent before you buy.
• Tell your home insurer before you fit the kit.
• Register the kit free at myplugin.solar before you first use it.
• One kit per household. Plug-in kits must not be used with a home battery.
