The Not-So-Secret Weapon For Scaling Your Business

Meter socket adapters have become standard operating procedure for some of the nation’s largest installers.

IslandDER by ConnectDER allows us quicker and cleaner installations, and we're excited to continue expanding its use in many of our markets.

IslandDER lets us deliver a comprehensive whole-home backup solution with 50% less installation time and over 50% cost savings. The need to install CTs in tight electrical panels has been eliminated, streamlining the installation process even further.

In the past we’ve had to move breakers and circuits, put them into a subpanel—a lot of labor, materials, time, and permitting that can add $5,000-$6,000 to a project. With IslandDER, you can leave all your loads in your main service panel.

You never know what you're going to find. A really old panel, it could be rusty, the wire size could be wrong. Using a ConnectDER MSA removes these variables, streamlines the entire process, and makes it more efficient and safe.

ConnectDER’s devices are easy to install and even easier to design with. Their Solar MSA helps especially with PV systems that are too large to interconnect with backfeed breakers and projects where standard line-side taps are not allowed or possible.

Meter socket adapters are paving the way for the future of Virtual Power Plants and energy storage. By helping to reduce costs, we're excited to see more of these innovative solutions like IslandDER becoming available in the market.

Retrofits are usually slowed down by panel upgrades, high labor costs, and long permitting timelines. With IslandDER, we bypass costly electrical work, cut install time, and reduce disruption for homeowners. Solar-plus-storage retrofits are faster, cheaper, and far more scalable.

By avoiding main panel upgrades, we save hours per job and significant labor costs, which lets us quote the homeowner a lower price. The EV MSA is like our secret weapon for winning more jobs.

Reduces timelines and minimizes the risk of installer error. You can provide whole-home backup for a fraction of the price of a dedicated load center that only provides minimal circuit backup. I would not do a solar and battery installation in today's market without a ConnectDER MSA.
