On July 28, 2026, the FCC added foreign-made power inverters to its Covered List — the national-security tool it's used before against companies like Huawei and ZTE. If you've been looking at a home battery, this week's headlines will be alarming. Most of that alarm is aimed at a different part of the market. Here's what actually changed, and what it means for a behind-the-meter home battery.
(This is developing news — the order landed on July 28. I'll update this page as the FCC and manufacturers respond.)
What the ban actually does
It blocks new FCC equipment authorizations for power inverters made outside the US — regardless of the brand's home country. In plain terms:
- New inverter models can't be approved for import, marketing, or sale in the US unless they clear a new Department of Homeland Security "conditional approval" security review (or move final assembly stateside).
- Products that already hold FCC authorization are unaffected. The FCC was explicit that previously approved inverters "can continue to be imported, marketed, sold and used." That covers the current-generation systems here — EcoFlow's DELTA Pro Ultra line and Anker's SOLIX E10 were authorized well before this.
- Nothing gets recalled, disconnected, or switched off. If you own one — or buy one that's on the market today — it keeps working.
Why grid-tied solar is having a much harder week
The projects genuinely stuck by this are grid-tied — the rooftop systems that sell power back to the utility through net metering, running a string inverter or microinverters. Their interconnection agreement is tied to a specific approved inverter model, so if that inverter can no longer be authorized, swapping it is a material change that sends the project back into the utility's engineering-study queue.
And that's where the squeeze is. The US-made inverter makers — Enphase, Tesla, SolarEdge — can still get new models approved, and they're the likely winners here (Enphase's stock jumped on the news). But domestic manufacturers are only about 7% of the US inverter market. The other ~93% is foreign-made — much of it Chinese brands like Deye, Growatt, and Sungrow — and those are exactly the inverters now frozen out of new authorizations, with no domestic factory ready to fill the gap overnight.
Why a behind-the-meter battery sidesteps it
Here's the part that matters for the systems we cover: EcoFlow and Anker home batteries aren't grid-tied in the first place. They're behind-the-meter by design — they charge from the grid when power is cheap and run your home when it's expensive, without exporting a single watt back. That means:
- No interconnection agreement
- No utility engineering study
- No net-metering enrollment
- No inverter model locked into a contract with your power company
The whole approval process that just seized up is a process these systems were never in — so the disruption hitting grid-tied solar doesn't reach them. And the specific models you'd buy today are already authorized on top of that. (Here's more on why these systems don't export to the grid.)
Sizing up the risk
There's no zero-risk version of this, so here's the straight ranking of what actually changed:
- Future models are on pause (real, slow-moving). Next-generation foreign inverters can't be authorized without clearing the new review. The catalog available today could be roughly the catalog available for a while — a one-to-two-year horizon, not weeks.
- Supply of current models could tighten (plausible). Already-authorized stock is legal to sell, but if imports slow or buyers pull purchases forward, prices on existing inventory are more likely to firm up than fall. Worth knowing — not worth panic.
- Your installed system keeps running (not a real risk). Nothing in the order reaches equipment already in the field, and the FCC said so.
- App and cloud support could slow years out (speculative). If a manufacturer's US business shrinks over time, cloud features and firmware updates could lag. It's one reason a system you can monitor and run locally — not fully dependent on a vendor's cloud — is worth valuing.
Neither EcoFlow nor Anker has issued a statement yet; the order just landed. I'll update here when they do.
Bottom line
For a grid-tied solar project, this is a serious disruption. For the behind-the-meter home-battery approach — charge cheap, run your home on it, no grid export — it mostly isn't: the models you'd buy today are already authorized, and the bottleneck applies to a grid process these systems never used. The one thing genuinely worth watching is future model availability, and whether prices on current hardware firm up.
Curious what a system would actually do for your bill? Run your Dominion bill through the analyzer — it uses your actual usage and today's prices, and it'll tell you plainly if a battery isn't worth it for your home.
