What ConnectDER does
ConnectDER is a Philadelphia-based solar technology company founded in 2011 that designs and manufactures meter socket adapters (MSAs), hardware devices installed between a residential utility meter and the meter socket to enable rapid interconnection of distributed energy resources. The company's three product lines — Solar MSA, EV MSA, and IslandDER — share a common 15-minute at-the-meter installation form factor that eliminates the need for electrical panel upgrades, line-side taps, or circuit relocations, addressing the primary cost and timeline barrier to residential solar, battery backup, and Level 2 EV charger deployment in older U.S. homes. ConnectDER's products include built-in circuit breakers, current transformers, voltage sensing, automatic grid disconnect, and (in the IslandDER line) Microgrid Interconnect Device functionality enabling whole-home battery backup with islanding capability.
The company sells hardware exclusively through a network of solar and electrical distributors — Baywa r.e., Soligent, U.S. Renewables, ABC Supply Co., Cooper Electric, and Quality Electrical Distribution — and maintains direct enterprise relationships with major national installers such as Sunrun. ConnectDER holds utility approvals across Arizona (APS, TEP, SRP), Illinois (ComEd, Ameren), California, Maryland, New Jersey, Texas, and Vermont, with each utility approval acting as a regulatory gatekeeper for at-the-meter installation in that service territory. Products are backed by a 12.5-year warranty, and the company has integrated with major battery OEMs including EcoFlow and FranklinWH.
ConnectDER has raised approximately $79M in disclosed venture funding across multiple rounds, including a $27M Series C led by Energy Innovation Capital (May 2023) and a $35M Series D led by Decarbonization Partners, the BlackRock/Temasek joint venture (December 2024). The company employs 11–50 people and has cumulatively deployed 15,000+ MSAs as of 2023. Its primary value proposition is a 10x cost reduction versus traditional panel upgrades, converting days of electrical work into a 15–30 minute installation and enabling installer economics that materially expand the addressable market for residential DER.

ConnectDER product offering
Product offeringCore offering
ConnectDER designs, manufactures, and sells patented meter socket adapter (MSA) hardware that connects residential distributed energy resources—rooftop solar, home battery backup systems, and Level 2 EV chargers—directly at the utility meter. The products (Solar MSA, EV MSA, and IslandDER™ MSA) install in approximately 15 minutes and eliminate the need for expensive electrical panel upgrades, line-side taps, and circuit relocations. The hardware is sold through distribution partners and direct enterprise relationships to solar, battery, and EV installation contractors across U.S. markets with utility approvals.
Product overview
ConnectDER offers a family of three meter socket adapter (MSA) products — IslandDER™ MSA, Solar MSA, and EV MSA — designed to facilitate the rapid, low-cost installation of distributed energy resources (DER) including solar, home battery backup, and EV charging. All three products share a common 15-minute at-the-meter install form factor that eliminates the need for panel upgrades, line-side taps, or circuit relocations, and are backed by a 12.5-year warranty. The Solar MSA serves rooftop solar interconnection; the EV MSA targets Level 2 EV charging installation; and the IslandDER™ MSA is the company's newest and most versatile product, enabling whole-home battery backup and solar-plus-storage with islanding capability for grid resilience.

ConnectDER competitors and assessment
Company assessmentDirect peers
- Span: Span makes a smart electrical panel that enables whole-home load management and DER integration without main panel upgrades—the panel-level alternative to ConnectDER's at-the-meter socket adapter approach. Both target the same installer pain point (electrical capacity constraints in older homes) and the same utility/government DER enablement market.
- Lumin: Lumin produces a smart energy management/load controller that addresses residential DER capacity constraints and enables solar, battery, and EV integration. It competes with ConnectDER for the same installer channel and addresses similar panel-upgrade avoidance use cases.
- Emporia Energy: Emporia offers energy monitoring, load management, and smart panel/EV charger integration products targeting residential DER enablement. It serves the same homeowner pain point and competes for installer adoption in the same channel.
- FranklinWH: FranklinWH manufactures whole-home battery storage systems that integrate directly with ConnectDER IslandDER, as evidenced by California San Diego deployment imagery on ConnectDER's product page. Both target whole-home backup and solar-plus-storage, and are co-marketed as a bundled installer solution.
- EcoFlow: EcoFlow's OCEAN Pro home backup battery system has a publicly announced integration partnership with ConnectDER IslandDER, enabling faster and more affordable solar-plus-storage installations. The two companies co-sell to installers as a bundled DER solution.
Broad incumbents
- Generac: Generac is a large incumbent in residential backup power (PWRcell battery, generators) and a broader home energy platform. Its smart electrical panel and battery products target overlapping whole-home backup use cases, though without ConnectDER's at-the-meter socket adapter positioning.
- Enphase Energy: Enphase is a leading microinverter and home battery (IQ Battery) manufacturer that ConnectDER Solar MSA is explicitly compatible with. Enphase's IQ System Controller and battery products compete for the same residential solar-plus-storage install channel.
- Tesla Energy: Tesla's Powerwall, Solar Roof, and Wall Connector ecosystem addresses whole-home backup, solar interconnection, and EV charging—overlapping with all three of ConnectDER's product lines. Tesla operates a proprietary gateway/backup architecture rather than an at-the-meter socket adapter approach.
- Eaton: Eaton is a major electrical equipment manufacturer with utility-grade meter socket products, breaker/meter combos, and established utility relationships. It could plausibly enter the residential DER socket adapter market with significant scale and incumbency advantages.
- Schneider Electric: Schneider Electric (Square D brand) is a global electrical equipment incumbent with existing meter socket, load center, and energy management offerings. It competes broadly with ConnectDER in residential electrical interconnection and could enter or expand in the at-the-meter DER adapter category.
