ConnectDER's IslandDER meter socket adapter has surpassed 1 million operating hours with a 99.6% reliability rate and received formal approval from PG&E, SCE, SDGE and SMUD, the company said in a [PR Newswire](https://www.prnewswire.com/news-releases/connectders-meter-socket-adapter-achieves-wide-scale-adoption-across-californias-largest-utility-territories-serving-over-35-million-residents-302936875.html) announcement on November 11, 2026.

## How IslandDER Bypasses Panel Upgrades

[ConnectDER](https://akta.pro/company-profiles/000075g/connectder) said IslandDER plugs into the existing utility meter socket outside a home, avoiding main panel upgrades, full service replacements, circuit relocations and subpanels. The device has been commercially available since the start of 2026 in PG&E, SCE and SDGE territory, and SMUD has now joined the list of approving utilities. Across the four service areas, IslandDER can be installed on roughly 10 million households, benefiting 35 million Californians.

More than 100 installers across California use IslandDER for solar-plus-storage, storage-only and storage retrofit projects. The device carries a built-in Microgrid Interconnect Device, current transformers, voltage sensing and communication protocols for real-time grid disconnect and home isolation, and handles meter-main combination panels in 15 to 30 minutes. IslandDER is compatible with battery systems from SolarEdge, FranklinWH, [Lunar Energy](https://akta.pro/company-profiles/00007qo/lunar-energy), [EcoFlow](https://akta.pro/company-profiles/00000p3/ecoflow-tech) and Fox ESS.

"IslandDER adoption in California has been swift from the moment field installs began, with positive installer feedback," said Ivo Steklac, ConnectDER President & CEO. "Heading into the fourth quarter, IslandDER is now a core operational tool among many of the state's top battery storage installers."

Lunar Energy, one of the compatible battery makers, announced an updated Lunar System battery and a new bidirectional EV charger on November 11, 2026, with installations starting in early 2027, according to pv magazine USA.

## ConnectDER's Earlier Utility Approvals

Company records show ConnectDER integrated IslandDER with EcoFlow's OCEAN Pro home backup battery system in May 2026, creating a bundled solar-plus-storage offering that bypasses complex electrical upgrades, according to [akta.pro company records](https://akta.pro/company-data). In January 2026, the company secured approvals from Arizona Public Service, Tucson Electrical Power and Salt River Project, enabling at-the-meter DER installation across Arizona.

## ConnectDER's Path to California Approval

ConnectDER announced in August 2026 the full integration and field availability of IslandDER with the SolarEdge Nexis home energy system, with installations already begun nationwide, PR Newswire reported. In October 2026, the company said its meter socket adapters were approved for installation across Pepco's Washington, D.C. service territory, bypassing main panel upgrades for solar, battery and EV charging installs, according to PR Newswire. Charged EVs reported in November 2026 that the UL-listed, NEC-compliant adapters had received Pepco approval for D.C. installations.

## IslandDER Availability Beyond California

ConnectDER said IslandDER is approved for behind-the-meter installation in utility territories including California, Arizona, Colorado, Illinois, Maryland and DC. Where meter socket adapters are not yet approved, IslandDER may be installed in a separate meter socket without utility approval, and the product is available for purchase through distribution nationwide.
