What it does

The ConnectDER EV MSA adds a dedicated 60A circuit at your meter socket — behind the meter, not in your main breaker panel. Built-in load sensing pauses your EV charger if total household demand approaches your service rating, then automatically resumes charging when load drops. No main panel work, no breakers added, no service upgrade.

When it fits

The MSA is the right choice when:

  • Single-family home with a 100A or 125A main breaker
  • You only need to add a Level 2 EV charger (other loads need Stepwise)
  • The home is in PG&E, SCE, or SDG&E service area (other utilities case-by-case — call us)

If your electrical panel is 150A or larger, or if you want to add other loads alongside an EV charger, see Stepwise Tap →

For homeowners

  • Skip the cost and the months-long wait of an electrical panel upgrade
  • Charging in days, not months
  • Federal 30C tax credit covers 30% of EV charger installation costs (up to $1,000) in eligible census tracts through June 30, 2026

For contractors

  • ~15 min hands-on install after utility coordinates a meter pull
  • Wholesale through GreenTech Renewables
  • 2–3× higher profit per hour than a main panel upgrade (MPU) on a similar job (per Stepwise’s published installer data)
  • We send utility approval documentation per job before you order

How the install works

  1. Confirm the fit — panel size, utility, customer info. Call us or use the form; we send approval documentation.
  2. Schedule the meter pull — typically a 1-week utility lead time.
  3. Install — ~15 minutes hands-on at the meter socket.
  4. Energize and pair — customer pairs their charger and starts charging the same day.

Frequently asked questions

What chargers are compatible with the ConnectDER EV MSA?

The MSA provides a hardwired 60A 240V circuit, so any Level 2 EV charger that hardwires to a 50–60A circuit is compatible (Wallbox, Tesla Wall Connector, Grizzl-E, Emporia, ChargePoint Home Flex, JuiceBox, and many others). Plug-in chargers using a NEMA 14-50 outlet require a separate outlet on the dedicated circuit.

Will my California utility approve it?

The ConnectDER EV MSA is approved for installation in PG&E, SCE, and SDG&E territory. For other California utilities (POUs, CCAs), approval is case-by-case; call us before ordering.

What happens when I run multiple appliances at the same time?

The MSA monitors total household current draw. If it approaches the service rating (typically at the 80% NEC threshold), it temporarily pauses the EV charger. Charging resumes automatically when the load drops. This usually happens briefly and only at peak times — most users never notice.

How does this compare to a smart splitter like NeoCharge?

Smart splitters share an existing 240V outlet (typically the dryer outlet) between two appliances. The MSA adds a new dedicated 60A circuit at the meter, which means much faster charging and no impact on existing appliances. The MSA is the better choice when you don’t want to share with the dryer (or don’t have a 240V dryer outlet near your charger).

Can I use this with solar?

Yes. The MSA is independent of any solar or battery interconnection. Add solar before or after.

Are California rebates available?

Federal 30C tax credit applies to qualifying EV charger installations in eligible census tracts through June 30, 2026. For utility and CCA rebates, eligibility depends on each program’s current qualified-equipment list. See the rebate guide → or call us at (858) 367-3617.

Does it work for other large loads besides EV chargers?

No. The MSA is designed specifically for Level 2 EV chargers. For electric ranges, electric water heaters, dryers, or other resistive loads, see Stepwise Tap →

Can it be installed on a 200A electrical panel?

No. The MSA is rated for 100A or 125A main breakers. For larger breaker panels, see Stepwise Tap →
