Manufacturer's warranty

10 years on the panels and on the mounting stand. The APsystems microinverter has its own manufacturer's warranty. Cables, connectors and accessories: 2 years

From the maker's datasheet (September 2026).

• 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 in the carton. The maker's manual asks for dense concrete blocks of at least 18kg each on the stand's lower plates, both sides: 2 blocks where gusts can top 40mph, 5 above 60mph and 10 above 80mph. Coastal and exposed sites need the higher counts, so plan block quantities per address.

Cables sit on top of the blocks, never trapped under them, and no block rests on the microinverter.

Ground only: a lawn, patio, gravel area or yard floor with about 3.7m × 1.2m of level space. Not for walls, roofs or balconies; the maker's datasheet says it isn't suitable for balconies.

Each kit plugs straight into a weatherproof outdoor socket (at least IP55) within its 4m cable. The maker designs the kits for an outdoor socket fitted and certified by a qualified electrician, with modern RCD protection in the consumer unit. No extension leads, cable reels or adaptors.

Across the North East, registration at myplugin.solar notifies Northern Powergrid, the network operator, for each address.

Run through these at each address before the kit is allocated. If one can't be ticked, that address waits.

1. Written permission from the freeholder or managing agent where you don't own the freehold, and the tenant told before install day.
2. A weatherproof outdoor socket within 4m of the spot, and modern RCD protection in the consumer unit. An electrician can fit or check both.
3. Straight into the wall socket. No extension leads, cable reels or adaptors, and the factory plug is never cut off.
4. One kit only at that address, and never alongside a home battery.
5. Registered free at myplugin.solar before first use, against that address.
6. The building insurer told before the kit goes in.
