Terra HP is a cabinet-and-charge-post DC charging system. ABB documents separate 175 and 350 configurations; vehicle acceptance, power allocation and operating conditions determine delivered charging power. Confirm the exact North American model before designing the site.
| Charger type | DC fast charging; separate power cabinet and charge post |
| Documented configurations | Terra HP 175 / Terra HP 350; exact generation must be specified |
| Rated output | 175 / 350 kW peak; 160 / 320 kW continuous in ABB North America chart |
| U.S. AC supply | 480Y/277 V, three-phase; final service design is site-specific |
| CCS1 output voltage | 150–920 VDC in the cited North America chart |
| Connector configuration | CCS1 documented; other connectors require exact SKU confirmation |
| Network integration | OCPP 1.6 Core and Smart Charging Profiles documented; verify selected backend |
| Site power allocation | Confirm cabinet count, connected posts and simultaneous-session limits |
| Enclosure | NEMA 3R / IP54 in cited chart; follow placement requirements |
| Payment and access | Specify terminals, authentication and operating contracts separately |
| Service and warranty | Obtain written coverage, exclusions and response commitments |
| Procurement | Confirm current supply and supported configuration; no stock commitment |
Evaluate arrival demand, dwell time, simultaneous charging and utility capacity before selecting the number of posts. Product selection alone does not establish funding eligibility.
Match vehicle charging curves and departure schedules to the proposed cabinet allocation. Include redundancy and a plan for vehicles that cannot charge during maintenance.
Define payment access, accessibility, communications and site support responsibilities before requesting an equipment-and-installation proposal.
| Line item | Scope to confirm |
|---|---|
| Charger package | Cabinet and post quantities, connectors, freight and commissioning |
| Electrical supply | Utility study, transformer, switchgear, protection and metering |
| Civil works | Pads, bollards, drainage, trenching and pavement restoration |
| Network and payment | Connectivity, backend onboarding and recurring service charges |
| Design and approvals | Engineering, accessibility review, permits and utility coordination |
| Ongoing operation | Maintenance, warranty exclusions and electricity demand charges |
| Project total | Site-specific written quote |
A funding award or utility contribution is not assumed. Request written eligibility and award terms before subtracting any contribution from the project budget.
Section 30C is unavailable for property placed in service after June 30, 2026. For qualifying property placed in service from January 1, 2023 through that date, the residential credit was 30% with a $1,000 limit per item at a main home. The business credit was 6%, or 30% when applicable prevailing-wage and apprenticeship requirements were met, with a $100,000 limit per item. Eligible location and other requirements still apply. The IRS defines an item as each charging port, fuel dispenser or storage property—not automatically an entire cabinet or household. Confirm historical eligibility and cost allocation with a tax adviser before filing Form 8911. Do not assume state or utility funding is available for a particular model or site.
