Do these inverters have an FCC ID?

No. The compliance route is a Supplier's Declaration of Conformity (SDoC) under FCC Part 15 Subpart B. SDoC does not carry an FCC ID, so any listing showing an FCC ID for these models would be incorrect.

What tests were performed?

Conducted emission to FCC 15.107 and radiated emission to FCC 15.109. Both passed. Testing ran from 2025-09-16 to 2025-09-22 with HE200-7200-F as the main test article.

Is SDoC equivalent to FCC Certification?

No. SDoC is a supplier's self-declaration supported by test data, not a certification issued by the FCC. The testing was carried out by Guangdong KEYS Testing Technology Co., Ltd.

FCC Part 15 Subpart B — SDoC, Not an FCC ID

One line: The FCC route for these models is a Supplier's Declaration of Conformity (SDoC) under Part 15 Subpart B — not an FCC ID, and we never state it as one.

Front three-quarter view of an inverter with the LCD panel — A unit from the covered model list, front three-quarter — the SDoC route is declared in the documents, not marked on the unit.

Rear rating label of an inverter showing the declaration-of-conformity statement — FCC compliance for these models is by Supplier’s Declaration of Conformity — there is no FCC ID on the unit or the label.

Document	Number	Issuing body	Date

Certification route

The route is SDoC — Supplier's Declaration of Conformity, under CFR 47 FCC Part 15 Subpart B, tested to ANSI C63.4-2014.

SDoC is not Certification. It carries no FCC ID. Devices approved through the certification route receive an FCC ID; devices declared through SDoC do not. We therefore describe these models as "FCC Part 15 Subpart B compliant (SDoC)" and no other way.

Test results

Test	FCC rule part	Result
Conducted Emission	15.107	PASS
Radiated Emission	15.109	PASS

Main test article: HE200-7200-F. Rated conditions in the report: AC 90–280 V, 50/60 Hz, 26 A, 6 kW. The remaining models are covered by the series model list.

Note: HE300-7200-F and HE310-5000-F are not in the FCC list. Those two models have CE EMC coverage and GB 4943.1 safety coverage, but no FCC file.

What SDoC covers and what it does not

It covers: electromagnetic emissions from the equipment under Part 15 Subpart B — the requirement for a device not to cause harmful interference.

It does not cover:

safety (that is a separate standard — see GB 4943.1-2022);
grid interconnection or utility approval;
an FCC ID, which does not exist for this route;
radio equipment approval — if a Wi-Fi module is fitted, it carries its own separate approval.

Reading the main test article correctly

The report's main test article is HE200-7200-F, and the other 22 models are listed in the series model list with the declaration that they share the same circuit principle, safety structure and critical components. This is the standard series-approval approach.

Practical consequence: if a buyer asks whether a specific I5 or HE500 model was individually tested, the accurate answer is that it is covered by series declaration, not individually tested. We state it that way.
