ConnectDER

ConnectDER is a Philadelphia-based clean energy hardware company and the leading US manufacturer of meter socket adapters (MSAs, also called meter collars) for the residential market. Founded in 2011 as Infinite Invention LLC after a DOE SunShot Incubator grant, it builds plug-and-play devices that install at the utility meter socket to interconnect distributed energy resources — rooftop solar, battery storage and EV charging — without panel upgrades, line-side taps or circuit relocations. Its product line is the IslandDER MSA (a microgrid interconnect device for solar-plus-battery and whole-home backup, integrated by SolarEdge, FranklinWH, Lunar Energy, EcoFlow and Fox ESS), the Solar MSA and the EV MSA. ConnectDER helped author UL 414 Supplements A, B and C, the standards governing meter socket adapters, and has surpassed 40,000 devices installed across US utility territories including PG&E, SCE and SDG&E. ConnectDER publishes no public developer API, SDK or machine-readable API contract; its devices communicate with partner battery systems over discrete hardwired sensing, control and status signals rather than a network interface. It does publish an llms.txt at its web root.

ConnectDER is profiled on the APIs.io network. Tagged areas include Company, Energy, Clean Energy, Distributed Energy Resources, and Solar.

ConnectDER’s developer surface includes FAQ, support, status page, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/connectder: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
