Charge smarter, pay less
Intelligent charging that adapts to your grid, energy prices, and solar production. Save money while charging sustainably.
Sunlight by day, cheap hours by night. Your car takes both, automatically.
Power Management
Optimize how much power flows to your charger in real-time, based on grid capacity and solar production.

- Scheduled ChargingSet high/low tariff windows
Power Management
Dynamic Load Balancing
Your main fuse has a limit. When you charge your EV while running appliances, you risk overloading the circuit. Load Balancing monitors consumption in real-time and adjusts charging to stay safe.
- Monitors main fuse via wireless meter
- Reduces charging when demand is high
- Peak Shaving to avoid demand taxes
- Prevents circuit breaker trips
Power Management
Solar Balancing
Use your own solar energy before it goes to the grid. The charger monitors your solar production and adjusts charging to maximize self-consumption. Free energy from your roof, straight to your car.
- Uses excess solar production first
- Reduces grid feed-in (avoids costs)
- Charges when your panels produce
- Works with any inverter brand
Power Management
Power Sharing
Split available power across multiple chargers intelligently. When one car finishes, others get more power. Perfect for homes with multiple EVs or small parking facilities. And in 3-phase installations it works phase-aware: power is distributed evenly across L1, L2 and L3, so one busy phase never slows the rest.
- Dynamically distributes available power
- Automatically rebalances as cars connect and disconnect
- Phase-aware across L1, L2 and L3
- No need for expensive grid upgrades
Tariff Management
Dynamic Tariff Charging
With dynamic energy contracts, prices change every hour. Plugchoice fetches the next day's prices and schedules your charging during the cheapest windows. Set your departure time and let the system optimize.
- Fetches day-ahead prices automatically
- Schedules charging in cheapest hours
- Automatic mode
- Works with all European energy providers
Tariff Management
Scheduled Charging
Not on a dynamic contract? Set fixed time windows for low-rate charging. Perfect for night tariffs or employer-subsidized charging windows.
- Avoid high tariffs
- Set custom time window
- Override for urgent charging
- Simple setup in the app
I used to dread my electricity bill after charging. Now with Smart Charging, my car charges on solar during the day and cheap rates at night.

Smart Charging FAQ
Why is Plugchoice free?
We make chargers, not subscriptions
Plugchoice is made by Volt Time. We earn revenue from selling hardware. The platform exists to make our chargers more valuable, not as a profit center itself.
Advanced features available
Some features like Solar Balancing and Dynamic Load Balancing are available as optional one-time purchases. Basic smart charging remains completely free.
View pricing detailsCan I switch between 3-phase and 1-phase for Solar Balancing?
Yes, with One Business
One Business switches between 3-phase and 1-phase charging via Plugchoice for more efficient solar utilization, maximizing your solar self-consumption.
Fixed configuration on other models
Our other chargers operate on a fixed phase configuration. They still support Solar Balancing, but without dynamic phase switching.
Do you support V2G (Vehicle-to-Grid)?
V2G ready with One Business
One Business features ISO 15118-20 support, preparing you for bidirectional charging as the technology becomes more widely available and vehicle manufacturers enable it.
Future-proof investment
While V2G is still emerging, investing in V2G-ready hardware ensures you're prepared when your vehicle and grid support it.
Does it work with my solar panels?
Works with any solar brand
All of our chargers support Solar Balancing with any brand of solar panels. We meter your main fuse, not the panels themselves, because what matters is excess solar power available.
Learn about Solar BalancingSmart metering included
Our chargers work with P1 port meters, CT clamps, and various EMS integrations to measure real-time energy flow.
