1 MW PV input
String Voc target ≤1,000 V at −5°C, with dedicated MPPT DC/DC and conversion headroom.
1,500 V DC-CLASS, DC-COUPLED TECHNOLOGY
1 MW PV. 2.5–5 MWh storage.
1.2–2.5 MW aggregate site charging capacity.
A scalable, off-grid-capable, 1,500 V DC-class system with dedicated PV MPPT, bidirectional battery DC/DC and an optional separate AC input cabinet.
SYSTEM ARCHITECTURE
Energy inputs, common DC bus and centralised charging with dynamic power allocation.
The target bus is at least 1,200 V within a 1,500 V-class system. Final interfaces remain subject to signed manufacturer data and system studies.
2.5–5 MWh storage
Up to 0.5C ramped output, governed by BMS, SOC, temperature and system limits.
1.2–2.5 MW aggregate site charging capacity
Available site power is dynamically allocated across an even number of charging dispensers.
Optional AC input
Grid, wind or diesel feed a separate transformer and AC/DC cabinet through a reserved 300 kW DC interface.
ENGINEERING BOUNDARY
Check available power and charging duration.
At 0.5C, 2.5 MWh corresponds to approximately 1.25 MW theoretical battery output and 5 MWh to approximately 2.5 MW, before SOC, temperature and system derating.
EMS available power is the minimum of BMS, 0.5C, busbar, cable, protection, thermal and charging-equipment limits. BIDC quantity is calculated from minimum battery voltage, the 100 A module limit, derating, N+1 redundancy and fault exit.
