What Plug-in Solar System Should I Buy?
Choose the electrical route first; only then compare products.

Daytime household offset points towards qualifying plug-in solar. Isolated loads point towards off-grid or portable power. Whole-home generation and storage point towards installed solar.
- Grid offset: compliant solar-only plug-in device
- Camping or backup: portable station
- Shed or office: off-grid system
- Larger home system: professional installation
Do not buy on commission or wattage alone
A useful recommendation must match the connection method, battery need, calculated load and documented product evidence.

What if I need a battery?
Choose portable, off-grid or professionally installed storage; the new plug-in route is solar-only.
