189 battery, PCS, BMS and EMS products with ★1
— A list with registration numbers, as of 12 November 2026

What a buyer checks in a project is not the nationality of a device. It is whether the model number of the device matches a product on IPA's list, and whether that registration number is valid now.

Here is a table for that check, taken from IPA's list and limited to solar and battery products. The 65 grid-scale products come first. Then come 61 residential ones, and 63 commercial or not determinable.

We assigned the use from the product names and the description on each product page. IPA's list has no field for use.

How to read the tables

• The registration number is a 16-digit number assigned by IPA. Click it to open the IPA page for that product. The page gives the model number, the maker and the support period.
• The type is our own grouping. "EMS / site controller" includes PMS and site EMS. "Remote monitoring / gateway / HEMS" includes gateways and HEMS. General-purpose routers (Century Systems, Teltonika, Moxa and so on) are not included.
• The HQ country is the country of the parent's headquarters. A Japanese subsidiary of a foreign parent is counted under the parent's country. For RENON POWER and LehmanSoft we could not confirm the parent's country, so we mark them "not confirmed".
• The expiry date is the day before the second anniversary of the acquisition date (the same notation as IPA). Rows that expire by the end of June 2027 are shaded yellow.

Terms used in this series

This series uses the terms below. All four articles share the same table.

Summary by type and country

Table 1 splits the count for each type of device by the country of the headquarters.

Table 2 splits the count for each use by the country of the headquarters.

The 10 that expire in May 2027

The requirement starts on 1 April 2027. The month after, the labels of the first products obtained expire. Table 6 shows those 10.

IPA said it would announce the details of the extension procedure "in 2026". As of 15 November, it has not done so.

A 2024 briefing document said that extensions would be accepted from 90 days before expiry, and that the fee would be the same as for a new application. The current fee for a new application is ¥198,000 (tax included). On 31 July 2026, IPA announced that applications had risen sharply and checks were taking time. It is safer to move early.

Examples of borderline products we left out: NST Globalist SpreadRouter-R, Nishimu Electronics TAMERBA power management unit, Ecomott cloud logger (2), Nissin Systems outdoor IoT gateway (2), Hitachi BCT control gateway, AZAPA NexusCore-TBOX, Watanabe Electric Industry Econo and DataChef, Nissin Electric FACTMATE-s1EX, Omron weather IoT sensor, Moxa MGate MB3000-G2 and others.

Limits of this table

IPA's list shows only labels that have been issued. From outside, we cannot tell applications in progress, rejections and non-applications apart. "Not listed" means only that no label existed at that time.

The counts come from IPA's Excel version (updated 12 November 2026), counted by registration number. The list is updated several times a month. Check the latest on the IPA pageJA.
