SolarEdge Technologies — 4 prefixes (MA-L / MA-M)

A MAC address beginning with one of SolarEdge's four registered prefixes belongs to SolarEdge Technologies, an Israel-based manufacturer of solar inverters, power optimizers, and monitoring/EV-charging hardware — typically seen on Ethernet-connected inverters, monitoring gateways, and EV chargers on residential or commercial solar installation networks.

The registrant holds four total IEEE assignments split across two block classes: two 24-bit MA-L prefixes (00:27:02 and 84:D6:C5) and two 28-bit MA-M prefixes (28:B7:7C:1/28 and 94:05:BB:A/28), all registered under "SolarEdge Technologies" at 1 Abba Eban St., Herzliya, Israel. A related legal entity, "Solaredge LTD." (Hamada 1, Herzliya, Israel), holds two additional MA-M blocks (48:0B:B2:5, 88:A9:A7:1) at a different Herzliya address; those are a separate IEEE registrant and are out of scope for this entry.

Device-type corroboration comes from Wireshark, which ships a dedicated "solaredge" display-filter dissector for inverter, optimizer, and energy telemetry fields, and from SolarEdge's own knowledge-center documentation describing LAN/Ethernet-connected inverters and MySolarEdge monitoring gateways that obtain DHCP addresses on installer and home networks.

SolarEdge Technologies, Inc. is a publicly traded (NASDAQ: SEDG) company founded in 2006, headquartered in Herzliya, with a multi-thousand-employee global workforce as of recent public filings. This corporate substance, combined with distinct OUI assignments to a named, address-matched registrant, places this entry well above the bar of a bare single-OUI shell registration.

No assignment date can be attributed to IEEE for any of these four prefixes — the public IEEE registry publishes no per-prefix date field, and any "registered" date shown by third-party lookup tools is a database artifact of that tool, not an IEEE fact.

Shared-base risk differs by block class here. The two MA-L prefixes 00:27:02 and 84:D6:C5 are direct 24-bit assignments to SolarEdge Technologies and carry no shared-base risk.

The two MA-M prefixes are 28-bit sub-allocations beneath bases the IEEE Registration Authority holds and sub-allocates itself: 28:B7:7C and 94:05:BB each list 15 MA-M sub-registrants, of which SolarEdge is one — 14 unrelated companies hold slices under each base. Neither /24 may be attributed to SolarEdge; only the pair-grouped /28 form identifies this vendor.

Shared-base risk

Split by block class — MA-L 00:27:02 and 84:D6:C5 are direct 24-bit assignments to SolarEdge with no shared-base risk; MA-M 28:B7:7C:1/28 and 94:05:BB:A/28 are 28-bit sub-allocations beneath IEEE Registration Authority-held bases (28:B7:7C and 94:05:BB, 15 MA-M sub-registrants each, 14 of them unrelated to SolarEdge), so neither /24 may be attributed to this vendor [Confirmed] — the IEEE MA-L registry 002702, the IEEE MA-L registry 84D6C5, the IEEE MA-L registry 28B77C, the IEEE MA-L registry 9405BB, the IEEE MA-M registry 28B77C1, the IEEE MA-M registry 9405BBA

Historic block

Special note

Two related registrant names ("SolarEdge Technologies" and "Solaredge LTD.") share addresses in Herzliya, Israel, consistent with the same corporate group registering blocks under legal-entity name variants rather than unrelated companies [Likely] — the IEEE MA-L registry, the IEEE MA-M registry

Related vendors

"Solaredge LTD." (same corporate group; separate IEEE registrant holding 2 MA-M assignments — 48:0B:B2:5, 88:A9:A7:1 — out of scope for this entry) [Likely] — the IEEE MA-M registry

Analyst note

A MAC in 00:27:02 or 84:D6:C5 — both direct MA-L assignments — reliably indicates SolarEdge-manufactured solar or EV-charging hardware; for the MA-M blocks only the 28-bit slices 28:B7:7C:1/28 and 94:05:BB:A/28 belong to SolarEdge, because their parent /24s 28:B7:7C and 94:05:BB are IEEE Registration Authority-held bases shared with 14 unrelated registrants each, so a MAC starting 28:B7:7C or 94:05:BB is not by itself a SolarEdge indicator [Likely] — the IEEE MA-L registry 28B77C, the IEEE MA-L registry 9405BB, the IEEE MA-M registry 28B77C1, the IEEE MA-M registry 9405BBA, wireshark.org/docs/dfref/s/solaredge.html
