Check the exact complete kit—not just the brand.

Seven checks

1. Exact identity: record manufacturer, kit name, model number and every generating component.
2. Whole-kit declaration: obtain the supplier’s declaration that the complete product meets the final plug-in-solar specification.
3. ENA record: find the exact generating unit on the G98 Type Test Register; similar names are not enough.
4. Output: confirm rated AC output is no more than 800W. Do not confuse panel DC wattage with inverter AC output.
5. Instructions: read connection, circuit, cable, mounting, weather, fire and notification instructions before purchase.
6. UK support: identify the legal manufacturer/importer, warranty provider, returns address and recall contact.
7. Complete contents: check what is included and whether the mounting method is approved for your proposed location.

Warning signs

• The seller will not provide an exact model number
• Only a marketplace screenshot or generic certificate is offered
• The listing says “EU compliant” but gives no Great Britain plug-in declaration
• The cable, plug or microinverter has been substituted
• Instructions encourage extension leads, adapters or improvised cable routes
• The listing mixes a storage battery into the same claimed qualifying device

After purchase

Save the invoice, declaration, manual, serial numbers, ENA register record and photographs of the installed position. Check the official product-safety alerts database periodically.
