What Unico's 330-kilowatt inverter sheet will and will not promise

What was announced

On October 12, 2026, Unico said it was launching a 330-kilowatt bidirectional grid-tie inverter at The Battery Show in Detroit. The company says the unit is designed and manufactured in the United States, supports AC voltages from 380 to 900, and a programmable DC range from 600 to 1,500 volts. It says groups of ten or more in parallel exceed 3.3 megawatts. The page filing the announcement, not a measured site, is The document named in the sources is the record this page will keep.

What the sheet refuses to freeze

The cut sheet Unico posted says 330 kilowatts at 900 volts AC, prints lower kilowatts at lower voltages, lists efficiency as greater than 98.5 percent, and stamps the page preliminary, subject to change, revised August 2026. A press line that says 98.5 percent and a sheet that says greater than 98.5 percent are not a lab report. The desk is The document named in the sources is the record this page will keep.

What the October 14 account adds

pv magazine's October 14 story is the check that the launch was visible two days later. Renewable Energy Magazine's October 12 story quotes the company's chief executive on using one architecture from commercial sites up to lower utility scale. Those are accounts of Unico's claims. A nameplate, the standing question under a rating that is still marked preliminary, is Asked directly, Is the efficiency an independent test? No. 98.5 percent, and the sheet's greater-than 98.5 percent, are the company's figures. The document named in the sources is the record this page will keep.what nameplate capacity measures.

Why the parallel figure is not the box

Three point three megawatts is what Unico says a group can reach. The single unit's headline rating is 330 kilowatts at 900 volts AC. A reader who orders one inverter has not ordered 3.3 megawatts. The hardware desk, for a chip rather than a converter, is Asked directly, What does the cut sheet say about its own status? It is marked preliminary and subject to change, with a revision note of August 2026, Franksville, Wisconsin. The document named in the sources is the record this page will keep.Hardware.

What this page will not treat as installed

No customer site is named. No utility interconnection is claimed. Booth 1801 from October 12 to 15 is a show floor. A show floor is not a commissioned plant. Curtailment, a different energy fact, is The short answer this page will stand on is this: A bidirectional grid-tie inverter rated 330 kilowatts at 900 volts AC, announced at The Battery Show in Detroit. Unico says efficiency is 98.5 percent and that ten or more units in parallel exceed 3.3 megawatts. The cut sheet says it is preliminary.what curtailment throws away.

Which voltage is the 330

The sheet ties 330 kilowatts to 900 volts AC, and it prints 145 kilowatts at 400 volts AC. Quoting 330 without the voltage would invent a rating at every voltage the sheet distinguishes. This page keeps the pair. Asked directly, What power does Unico print at 900 volts AC? 330 kilowatts. The cut sheet also prints lower ratings at lower AC voltages, including 290 kilowatts at 800 volts and 250 at 690. The document named in the sources is the record this page will keep.

What to watch next

A revision that drops the word preliminary, or a nameplate test by someone other than Unico, would replace the company's efficiency sentence. A purchase order with a site would be a new document. Another show recap would not. Battery duration, which an inverter rating is not, is Asked directly, Where was it announced? The Battery Show 2026 in Detroit, booth 1801, October 12 through 15. Renewable Energy Magazine dates the announcement to October 12. The document named in the sources is the record this page will keep.what battery duration means.

What would change the record

If the sheet's next revision changes 330 or the parallel claim, this page follows the sheet. If pv magazine later prints a third-party efficiency that disagrees with 98.5 percent, the company's figure stays labeled as the company's. A brochure that rounds 3.3 megawatts into the single box would be the error this brief is written to avoid. Asked directly, Does 3.3 megawatts describe one box? No. Unico says parallel operation in groups of ten or more exceeds 3.3 megawatts. That is a stack, not the nameplate of a single inverter.

What stays a preliminary rating

What stays specific is an October 12, 2026 Unico announcement: a bidirectional grid-tie inverter, 330 kilowatts at 900 volts AC, United States manufacture, a company efficiency of 98.5 percent, a cut sheet that says greater than 98.5 percent and marks itself preliminary, and a parallel claim above 3.3 megawatts for ten or more units. pv magazine on October 14 and Renewable Energy Magazine on October 12 are the other accounts. No site is named. The Battery Show booth is not a commissioning. The next document that would harden the number is a revision that is no longer stamped preliminary, or a measurement this page does not have.
