That's why I said, "it's likely a product for hackers".

This type of inverter might be useful for people living off the grid, or people who
have part of their home (like the garage) off the grid.

It might only require a simple battery and 12VDC to 120VAC inverter to Boot it up.
Or anything that could supply a fake grid voltage to the unit.

Once the inverter was running (with PV supplying the juice), the power
could be used for any kind of load within it's power range.

Like running an AC on those really sunny days..
(Might have to stack a few inverters)..

~~~

Or, if someone had an off-the-grid system and the inverter section was
maxed out, so that no more panels could be added, these mini-inverters might be very useful.

One unit could be used with each new 220W PV panels added to the old system.
But the DC from the new panels goes right to the new inverter and it's AC output goes right into the house wiring..
The new panels bypass all the old system's DC hardware and the new AC power syncs up with the old system's output.

A cheap and easy way to add-as-you-grow your PV system..

DIY people who hack their own hardware know they risk insurance not paying
off if their fire or other damage was caused by non-approved devices.

That's the main reason why Hams with older non-UL listed power supplies
should disconnect those devices when they are not in use..

I wouldn't plug in anything until I was happy it wasn't poorly made, as to be dangerous.

When I get a new wall-wart, I always monitor how much heat it's producing, before letting stay plugged in, unattended..

I have tossed out or modified a few cordless phone chargers..
(When you pick up your cordless phone, it shouldn't feel hot).


Humm, I wonder if my gas powered back-up generator is UL listed???
