Project Procurement Shortcut

Which EV charging solution should a buyer start with?

Start from the site use case, not from a product list. Commercial parking and hotels usually need many AC wallboxes plus a small number of DC fast chargers. Fleet depots need DC charging, load management and scheduled operation. Highway sites need higher-power DC chargers, payment and remote diagnostics. Weak-grid or solar-assisted sites may add battery storage as supporting infrastructure, but AC/DC chargers should remain the main procurement scope.

Commercial parking

Plan AC wallboxes for dwell-time charging and DC fast chargers for high-turnover users.

Fleet depot

Plan DC charging by route schedule, vehicle battery size, transformer capacity and OCPP/CSMS control.

Highway charging

Compare 150kW, 180kW, 240kW and higher DC chargers against grid capacity and traffic.

Weak-grid support

Use solar and battery storage only when the charging site needs peak shaving or grid reinforcement.

Market details

Country, grid voltage, connector standard, certification needs, quantity and delivery timeline.

Procurement FAQ

Questions buyers usually ask before the first quotation

Should a project choose AC or DC charging first?+

Choose AC charging for longer parking time and lower installation cost. Choose DC charging when vehicle turnover and charging speed are the main project requirement.

When should a site add battery storage?+

Battery storage should support weak-grid, peak-shaving or solar-assisted charging sites. It should not replace clear AC/DC charger selection.

What information helps SUNFULL prepare a site proposal?+

Send site type, available power, target charger mix, connector, OCPP/payment needs, country, quantity and timeline.
