kalakoa - Inverters sold in the US are generally required to comply with IEEE 1547, which probably exceeds any safety requirements the State can mandate.
Ah some Actual Intelligence, instead of article summaries from a CSAM generator. Any insights kalakoa if the HECO smart meters could detect the use of plug-in solar, other than the average metered usage drop? The panels and microinverter look to be simple enough, it's all the new UL 3700 touch safety/backflow/etc protections that seem to not have hit the markets yet. Literally asking for a friend who is still tied to the grid in Puna. Thanks!

Supposedly the smart meters can detect plug-in solar, but I'm pretty sure that only works if you actually generate a surplus.
I knew a guy who was using plug-in solar on the Big Island, definitely trimmed the electric bill, no problems, but this was years ago before smart meters.

GROK agrees, says (fwiw):
HECO’s advanced meters are bidirectional, meaning they measure and record electricity flow in both directions—usage from the grid and any exports back to the grid.  This allows detection of reverse power flow or backfeeding, which can occur with plug-in solar if generation exceeds on-site consumption at any given time.  Such detection goes beyond just observing an overall drop in average metered usage, as the meters capture data in 15-minute intervals and can flag unauthorized exports or failures in non-export systems.   For self-supply or non-export setups, HECO uses these meters to monitor compliance, with allowances for minimal inadvertent exports (e.g., up to 60 seconds, no more than twice per day); exceeding this can trigger investigations or corrective actions.  If plug-in solar is installed without an interconnection agreement, any detected backfeed could lead to utility intervention, as unauthorized exports are prohibited under HECO’s rules. 
Cheers,

Begging randomq's indulgence, and riffing on the thread's "Li-Fē-P-O" title, did you know that apparently George Lucas fled to Hawai'i during the opening of Star Wars in 1977, fearing the possible bad reviews? While chilling on the local beaches with Steven Spielberg and reminiscing about their favorite spy and adventure films, Lucas pitched him on an idea he had for a daring archeologist that had to locate the Ark of the Covenant before Hitler and the "Roman saluting" Nazi's could get their hands on it - the adventures of Indiana Smith! (was still a work in progress - needed a few more mai tais to workshop it ;)
So what's all this got to do with the price of picking up a power converter in Tosche Station (other than no can ship them either)? Well, while doing the monthly maintenance yesterday on our own moisture vaporators, some variation of the wise words of Alec Guinness as Obi-Wan came to mind in considering how to deal with "mecha-hitlers" - it's more machine slop than human wisdom now, twisted and evil - as well as those pale leaders of aspiring evil empires: "Who's the more foolish, the fool or the fool who follows him?" ;)

I will indulge. And in fact, if one had surplus power, one could use a relay to activate these real life moisture vaporators, which would perform swimmingly in our un-Tatooine-like climate: https://www.amazon.com/Pure-AirWater-Atm...B0DRT13NS5

Much appreciated - may the midi-chlorians bless and keep you!
Do you, or someone you know in Hawai'i, have one of these "water generators"? $1500, and what looks like a constant 230W across 24 hours for 2.6 gallons of water seems like a lot of inputs and time when the stuff keeps constantly falling from the Puna sky by the bucket full for free.
Maybe more useful on the islands' dry and overly sunny sides, or up mauka from there, like those local efforts at fog harvesting?

I do not, but I think they're neat. Still, the price and power do seem a little ridiculous. All I have to do is take a can of coke out of the fridge and forget it on the counter to get a cup of water!

New story about plug in solar panels in NYT:
https://www.nytimes.com/2026/07/31/busin...-ios-share
In the article they mention a company that sells plug in panels to all 50 states, although they’re not approved in all 50 states, yet:
https://craftstrom.com
(Read earlier comments in this thread about HECO concerns, and detection)
When circuits are overloaded, breakers can trip to prevent fires and damage to the electrical equipment.
A plug-in solar system that lacks UL 3700 certification could mask how much electrical current is flowing on a particular circuit because the panels are supplying electricity. In that case, a breaker might not detect that the circuit is being overloaded by other appliances on the same circuit.
“The holy grail is to wait and make sure it is listed to UL 3700 certification,” said Bernadette Del Chiaro, a senior vice president at the Environmental Working Group, a nonprofit organization focused on health and safety. “It puts all the onus on the manufacturers to put in safety devices.”
