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 Jávea

In Jávea (Xàbia), one of the great foreign-resident destinations on the Costa Blanca, many EV chargers are in villas of the Montgó estates, frequently integrated with solar self-consumption installations. Faults here are rarely simple: 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 Jávea, serving British, German and Dutch owners in their language, both in the Montgó villas and in the Arenal apartments. We review the integration with self-consumption, the solar-surplus charging configuration and the protections, because the fault usually lies in the coordination between systems, not in a single unit.

Solar surplus charging that stops working

In the Montgó villas many chargers are set to start only when there is solar surplus. When that mode stops working, the cause is rarely the charger: it is usually the surplus meter or its current clamps, which have shifted, lost contact or were refitted the wrong way round after work on the panel.

It is diagnosed by comparing what the meter reports against an independent measurement while the system is producing. Another frequent cause is an inverter firmware update that changes the protocol and breaks the dialogue with the charger. We check both and leave surplus mode working and verified with the car plugged in.
