Modular DCFC built for fleet depots. One Power Unit feeds 1–8 Satellites with dynamic load sharing — charges 8 vehicles efficiently from a shared transformer.
| Charger type | DCFC — modular (Power Unit + Satellites) |
| Max power output | 200–600 kW Power Unit → 50–400 kW/Satellite |
| Output voltage | 150–1000 VDC |
| Connectors | CCS1 + NACS variants (per Satellite SKU) |
| Networked | Yes — Kempower ChargEye platform |
| OCPP version | OCPP 2.0.1 |
| NACS support | Yes — Satellite NACS SKU available |
| Enclosure rating | Outdoor IP54 |
| Cable length | 16–23 ft (Satellite cables) |
| Architecture | 1 Power Unit + 1–8 Satellites, dynamic load sharing |
| Warranty | 3-year standard |
| Country of origin | Finland |
School bus, transit, and class 4–8 fleet depots charging 8–20 vehicles overnight. One Power Unit + 8 Satellites hits 8 vehicles on one transformer, cutting service upgrade cost.
Transit agencies standardizing on one platform. Kempower is the largest DCFC OEM in European transit; NA transit deployments have ramped fast since 2024.
Retail or workplace sites where 4–8 vehicles arrive together and share available power. Dynamic load sharing hands more kW to whichever vehicle accepts it fastest.
| Line item | Typical range |
|---|---|
| Power Unit (200–600 kW) | $80,000 – $110,000 |
| Satellites (each, 50–400 kW) | $20,000 – $30,000 |
| Switchgear and transformer tie-in | $20,000 – $60,000 |
| Trenching, conduit, satellite cable runs | $15,000 – $40,000 |
| Concrete pads + bollards | $10,000 – $20,000 |
| Commissioning, ChargEye setup, OCPP integration | $4,000 – $10,000 |
| All-in installed total / 4-Satellite fleet site | $225,000 – $380,000 |
Adding Satellites is cheaper than adding a full DCFC because the Power Unit, switchgear, and one transformer tie-in are already paid for. Scale economics favor 4+ Satellite configurations.
Section 30C commercial credit covers 6% of cost (or 30% with prevailing wage + apprenticeship), capped at $100,000 per item, when the C-Series is installed at a property in an IRS-designated low-income or non-urban census tract. Each Satellite counts as a separate item for the $100K cap, which is advantageous for modular deployments. Must be placed in service by June 30, 2026.

Integrated dual-port 350 kW cabinet. Right choice when each port needs full peak power and the service network advantage matters more than load sharing.
View spec
Level 2 (22 kW) workplace and depot overnight charger. Pair with Kempower Satellites for dwell-time + fast-charge hybrid depot design.
View spec
Compact integrated 150 kW DCFC. Better footprint, simpler project, but no dynamic load sharing across units.
