Wallbox chargers

Wallbox is a Spanish manufacturer of electric vehicle chargers based in Barcelona. Its Pulsar and Commander models are among the most widely installed in private homes in Spain, and here you’ll find them alongside technical advice on power output, safety features and integration with solar panels.

Which Wallbox charger do I need?
The choice depends on three factors: the contracted power rating for your home, your car’s on-board charger, and whether your supply is single-phase or three-phase.
7.4 kW single-phase This is the correct setting for most Spanish homes: it recovers around 40 km of range per hour, meaning that a 60 kWh battery is fully charged overnight.
11 or 22 kW three-phase It’s only worthwhile if you have a three-phase supply and the car supports three-phase charging on board. Many vehicles limit AC charging to 7.4 or 11 kW, so installing a 22 kW system doesn’t always mean faster charging.
If your car is a plug-in hybrid, 3.7 kW is more than enough: its on-board charger rarely accepts more than that.

Dynamic power control
This is the function that prevents the circuit breaker from tripping when you’re charging your car and using the oven at the same time. The charger measures the power consumption of the rest of the house via a meter on the main fuse box and adjusts the current it supplies to the car in real time.
If you have a contracted power of 5.75 kW and do not wish to increase your power — which would make your fixed charge more expensive — this feature is not optional.

Charge your car using your solar panels
With surplus energy management, the charger uses only the energy that you would otherwise feed into the grid. In a 5 kWp installation, that could amount to 20–30 kWh a week, which, instead of being sold at the surplus price, is used to charge your car practically for free.
For it to work, you need a energy meter in the panel and ensure that the charger communicates with the installation. We also have native alternatives from other ecosystems: the charging station Victron EVCS and the Fronius Wattpilot.

Installation
It must be carried out by an authorised installer, with its own circuit from the distribution board and dedicated protective devices. In a owners’ association, the prior notification required by the Horizontal Property Act is sufficient: no approval at a general meeting is required.
