Compare California EV install paths: standard, load management, meter adapter, panel upgrade
Cost, profit per hour, install speed, utility coordination, and best fit for each path. Use this to decide which install to quote — and when.
| Install path | Typical $ range | Profit per hour | Install speed | Utility involvement | Best fit |
|---|---|---|---|---|---|
| Standard install | $300–$1,500 installed | Moderate | Fast | No | Plenty of panel space and capacity |
| Load management (Stepwise) | Significantly less than panel upgrade — contact for quote | Highest profit per hour | Very fast | No | Tight capacity, no utility delay wanted, non-EV resistive load, multifamily |
| Meter adapter (EVMSA) | Significantly less than panel upgrade — contact for quote | Strong | Moderate | Yes (meter pull only) | Full panel, EV-only on 100A or 125A |
| Panel upgrade (MPU) | $5,000–$25,000+ installed | Often lowest profit per hour | Slow (3–9 months) | Yes | When other paths are not viable |
Actual cost and profitability depend on service equipment, utility requirements, trenching, conductor length, and local labor conditions.
When each path makes sense
Standard install: lead with this when the panel has space and capacity. Easy close, easy install.
Load management (Stepwise): lead with this when the customer has been told “you need a panel upgrade.” Frame as “we have a faster, less expensive alternative.” Best for any electrical panel up to 200A, non-EV resistive loads, or multifamily applications.
Meter adapter (ConnectDER EV MSA): lead with this when the breaker panel is full but the customer only wants an EV charger and is in PG&E, SCE, or SDG&E territory on a 100A or 125A panel.
Main panel upgrade (MPU): position as the fallback only when other paths don’t fit. Be transparent about cost ($5,000–$25,000+) and timeline (3–9 months) so the customer doesn’t feel oversold.
Which xCA product matches each path
- Load management → Stepwise Tap (electrical panels up to 200A, one resistive load per Tap, no utility coordination)
- Meter adapter → ConnectDER EV MSA (100A/125A breaker panels only, EV-only)
