Maximum Efficiency.
Minimum
Energy Loss.
Direct DC coupling between solar generation, battery storage and ultra-fast EV charging for maximum system efficiency.
The Most Efficient Path
from Sun to Vehicle
In a DC-coupled system, solar panels, battery storage and EV chargers share a common DC bus. This eliminates the multiple AC/DC conversion stages required in traditional AC-coupled architectures, reducing energy losses and maximising the utilisation of every kilowatt-hour generated.
The WOX DC Coupling solution is designed for enterprise customers requiring high-throughput EV charging with integrated renewable generation and storage — from highway charging hubs to industrial fleet depots.

Why DC Coupling Outperforms
Maximum Charging Efficiency
Direct DC path from solar to charger eliminates AC/DC conversion losses, achieving up to 97% system efficiency.
Lower Conversion Losses
Fewer power conversion stages mean less energy wasted as heat, reducing operating costs significantly.
Reduced Grid Dependency
Solar and battery buffer absorb peak demand, reducing grid import costs and exposure to tariff volatility.
Peak Shaving
Battery storage flattens demand peaks, avoiding expensive grid capacity charges and transformer upgrades.
Higher Renewable Utilisation
Excess solar generation is stored rather than curtailed, maximising return on PV investment.
Future-Ready Architecture
Modular DC bus design supports V2G, additional storage and higher-power chargers without system redesign.
