Why does my Wallbox charger show a red light?

A red light usually means an earth fault, a communication error with the car, overheating or a tripped RCD. We diagnose the exact cause and repair on site where possible.

How much does EV charger repair cost in Alicante?

The diagnostic visit starts from €80 and is deducted if the repair goes ahead. The final cost depends on whether the fault is in the wiring, the Wallbox or the RCD.

EV Charger Repair in Altea

In Altea, known for its luxury hillside villas and a demanding clientele, EV chargers are usually high-end units installed in villas with complex panels and, often, energy management systems and solar panels. Faults here are rarely trivial: they involve communication between the charger, the solar inverter and the load management, and require a diagnosis that understands the whole installation.

We repair chargers in the villas of Altea, Altea la Vella and Sierra de Altea with the discretion and care these homes require. We review the charger's integration with self-consumption, the solar-surplus charging configuration and the protections, because in these installations the fault usually lies in the coordination between systems, not in a single unit.

Charger, inverter and load management: isolating whose fault it is

In the Altea villas the charger almost never works alone: it talks to the solar inverter, to a consumption meter and to a management system that decides how much power to release at any moment. When something fails, each manufacturer points at the other, and the owner is left between two support desks that do not speak to each other.

Our job there is to isolate the failing layer. We read the charger's and the inverter's logs, check the meter and its current transformers, and force a charge in manual mode to see whether the unit responds with the management out of the loop. That test establishes whose fault it is and stops the circling.
