Dedicated MPPT supplies active DC loads first while surplus power can charge the battery.
SOLAR + BATTERY + EV CHARGING
Use solar and storage to place charging power where the grid cannot readily provide it.
EV Whale combines dedicated PV MPPT DC/DC, high-voltage battery storage, a 1500V-class common DC bus and central charging output in a modular all-DC architecture.

PROJECT CHALLENGE
Conventional charging can make the grid connection the project bottleneck.
- New high-power loads may exceed switchboard, incoming cable or local network capacity.
- Repeated AC/DC conversion adds equipment and conversion loss when the main sources and loads are DC.
- Fixed, tightly integrated equipment can make later maintenance and technology replacement expensive.
DELIVERY APPROACH
Coordinate generation, storage and charging on a common DC platform.
Bidirectional BIDC modules stabilise and support the bus during solar shortfall or night operation.
A dynamic power pool distributes available power across the connected terminals.
Grid, wind or diesel can connect through a separate transformer and AC/DC cabinet when required.
LIFECYCLE VALUE
Reduce conversion stages and preserve upgrade boundaries.
PV equipment, the integrated DC bus and BIDC cabinet, battery containers and charging cabinets are separated so capacity, failures and technology upgrades can be managed by module.
FAQ
Questions project teams ask
Does solar power have to pass through the battery first?
No. The common DC bus can allow PV to support charging directly, with surplus power stored and the battery supplementing shortfalls.
Is the common bus fixed at 1500V?
No. It is a 1500V-class system. The target operating range must be confirmed with the battery, BIDC and DC-input loads.
Does the system eliminate all grid work?
Not automatically. It can reduce dependence on grid upgrades, but site, electrical and network studies remain necessary.
