What output do I need for a residential charger?
+
An 11 kW charger (three-phase 16 A) covers 95 % of residential needs: it charges an electric car from 0 to 100 % in 6 to 8 hours, i.e. one full night. A 22 kW charger halves this time but requires a 32 A three-phase installation and approval from the grid operator.
How much does EV charger installation cost?
+
Budget 1,800 to 3,500 CHF all-in for an 11 kW residential charger (equipment, installation, connection, configuration). For a 22 kW charger or a multi-charger site, the quote depends on the electrical upgrades required and can range from 2,400 to 5,500 CHF depending on complexity.
How does the charger synchronise with my solar panels?
+
We install a smart meter that measures your solar production in real time and controls the charging. The car can be charged solely on your solar surplus, or in mixed mode (solar priority with grid top-up to finish the charge). All fully configurable.
What is OCPP?
+
OCPP (Open Charge Point Protocol) is the open standard for charger management. It allows your charger to be supervised by any compatible platform, without depending on the manufacturer. All chargers we install are OCPP 1.6 or 2.0.
Is a permit required to install a charger?
+
A notification to the grid operator (Romande Energie, SIG, Groupe E) is mandatory before installation, to verify that the connection can support the output. No building permit is required for a residential charger installed indoors or against the façade.
Can a charger be installed in a rental property?
+
Yes, with the landlord's written agreement. The charger generally remains the property of the tenant, who can remove it on departure. Connection costs and associated consumption are the tenant's responsibility.
Can multiple chargers be installed for a company fleet?
+
Yes. We install multi-charger sites (up to 30 charge points) with dynamic power management to avoid electricity subscription overruns. OCPP supervision allows centralised settings and billing.
What does charger consumption cost?
+
It depends on your mileage. A car consuming 18 kWh/100 km and covering 15,000 km/year uses 2,700 kWh/year, approximately 750 CHF/year at standard electricity rates. With charging mainly on solar surplus, the cost can fall to 200–300 CHF/year.
Which charger brand should I choose?
+
Fronius Wattpilot Flex 11 is our default reference: native solar coupling, configurable 11/22 kW, seamless integration with a Fronius inverter — freestanding pedestal available as option. Easee Charge Core stands out for its minimalist Scandinavian design and modular installation. KEBA P30 is a reliable Swiss premium reference. For commercial use, EVBox Elvi is our go-to reference.
