The company’s LinkedIn post highlights IslandDER™ as an all‑in‑one meter isolation device and grid disconnect aimed at simplifying and standardizing residential energy storage and related installations. The post also points to compatibility with batteries from Lunar Energy, FranklinWH Energy Storage Inc., SolarEdge Technologies, EcoFlow, and a forthcoming integration with Fox ESS.
According to the post, IslandDER™ is positioned to reduce installation time, avoid main panel upgrades and service upsizing, and replace traditional battery gateway components, potentially lowering labor and permitting complexity for installers. These features could enhance installer economics and support broader adoption of distributed energy resources and home batteries.
The post suggests that early field deployments with three of California’s largest investor‑owned utilities may help validate the product in one of the most advanced U.S. markets for solar and storage. If adoption scales, this presence could strengthen ConnectDER’s role in grid‑edge hardware, support revenue growth tied to storage and retrofit demand, and improve its competitive position as installers prepare for increased activity into 2026.
