Intelligent Energy Management for Your Charging Infrastructure
Run multiple charging points without costly grid upgrades. The SmartBox protects your main breaker and optimally uses your solar energy – Plug & Play.
Why Energy Management Is Essential
Without DLB you risk overloads, high costs, and wasted solar potential.
Main breaker protection
Home consumption + EV charging = overload. The SmartBox measures total consumption in real time and automatically throttles charging power before the breaker trips.
Avoid grid upgrades
Multiple charging points normally require an expensive grid connection upgrade. DLB distributes available power intelligently – no electrician, no construction.
Use PV surplus
Your solar system produces surplus during the day? The SmartBox directs it straight into your EV – charge for free with your own solar energy.
Autel SmartBox – The Heart of Your Energy Management
