Charging your electric car with solar power: how to do it properly
Hybrid Solar team · 22 April 2026 · 1 min read
Wallboxes, solar mode, contracted power and the mistake that has many people charging from the grid without realising it.
Pure solar mode vs. mixed mode
In pure solar mode, the charger only starts when there is enough surplus. In mixed mode, it tops up with power from the grid to make sure the car is charged by a set time.
How much power you need
A 7.4 kW single-phase charger adds around 40 km of range per hour — more than enough for daily use with overnight charging.
Integration with the system
The wallbox should communicate with the inverter and the energy meter. Without that integration, charging can trip the main breaker or draw power from the grid unnecessarily.
