Solar panel into 110V grid

[rubberlegs]

I have a 90W solar panel from my RV that's just sitting in the garage. In Europe people plug solar right into their house outlet. I'd love to do that. It seems so simple. OK, at 90W it's just as a hobby I suppose, but every little bit helps. Maybe I'll expand one day.

What equipment do I need?

Does this thing have real Rapid Shut-Down as some of the reviews claim?
Is it REALLY a UL RATED product?
It'll be illegal pretty much anywhere in the US.
If your house burns down, your insurance folks are going to laugh all the way to denying your claim.
Your Utility might reserve the right to disconnect you entirely for an illegal hookup.
What else is already on the 20a circuit you'd be plugging into?
IMHO, I wouldn't touch one of these things with a 10 foot pole, but YMMV.
Just stay safe, and have a good weekend.

Oh come on. Probably produces 4 amps for an hour a day.

A possible useful way to use that panel is to charge a cell phone.

Just attach it directly to a USB charge port, such are used in mobile applications.

For instance, something like this:

12/24V DC Dual USB Charger 4.8A with Intelligent Device Recognition - Blue Sea Systems

Engineering high quality marine electrical components for safety, reliability and performance

There are many brands and they are sold all over the place, just make sure that it is a dual 12 / 24 volt version.

These intelligent units will adjust to the power available and the device being charged, at least enough to get the job done.

No battery is required - I have tested this particular one and it worked with a 150 watt panel on my driveway.

They shouldn’t be selling that product.

It’s not code nor POCO compliant

It is certainly a very dangerous product in so many ways.
Back feeding the grid during a power outage is one of them.
Burning down your house when this tiny cheap inverter fails or overheats and catches fire, is another.

It isn’t a big technology lift to make a 1741 grid tie compliant , interactive inverter (excluding any sections about using non-dedicated circuits)

The problem is that in the absence of sanctioned use, there is nothing enforcing sanity or safety.

Correcting "Proceed with Caution" review. For any grid tied system, it is required to shut down when the there is a power outage per IEEE 1547 guidelines. If you look at the spec sheet for the NEP microinverter it does meet IEEE 1547 guidelines as all products sold in the USA should. Therefore there is no risk of shock when the power goes down, it will ONLY function when it sees the 120v grid signal.
That being said, an electrician would tell you that this device should be connected to a dedicated circuit because in theory there is the potential to exceed the current rating of the home wiring without tripping the breaker. Another option would be to downsize the breaker from 20A to 15A to compensate for the potential 5A power increase created by this device. This way the 15A breaker would trip at the 20A max current rating of the home wiring.
