Charge your EV using surplus solar energy
Stop exporting solar at low rates and buying it back expensive. Monta Solar charging automatically steers your surplus energy to your EV, so every kWh your panels produce charges your car instead of subsidizing the grid.
24+ solar inverter brands supported via Enode integration
Solar + Grid or Solar Only
Solar + Grid mode tops up from the grid if solar production falls below the 6A minimum threshold, ensuring charging continues even when the sun dips behind clouds. Recommended for smaller arrays under 6 kW. Solar Only mode charges exclusively when surplus meets the threshold, pausing when the sun goes down and resuming when it returns. Recommended for larger arrays over 6 kW where you want 100% solar-powered charging.

Three ways to integrate Solar charging
Choose the method that matches your accuracy needs and budget. All three work with any Monta-supported charge point.
Meter Integration
Uses smart meter readers to measure both household consumption and solar production in real time. The system adjusts EV charging so that solar production minus household consumption equals EV charging power, steering your home toward net-zero grid consumption. Supported devices include Saveeye+, Powerfox, Stromleser, and charger-connected CT clamps.
Inverter
Connects directly to your solar inverter to read live production and household consumption. The system adjusts EV charging to match your available solar surplus, maximizing self-consumption with no additional metering hardware. Works with compatible inverters.
Forecast-Based
Uses weather data and your panel specifications (peak output, tilt angle, orientation) to predict solar output. No additional hardware required. Slightly lower accuracy than meter or inverter methods, but perfect for getting started with no upfront investment.
Compatible with your charge point
Solar charging works with 930+ charge point models. We’ve ranked every model using a scoring system based on actual usage data to help you choose the best fit for solar optimisation.
FAQs
What happens when it's cloudy or raining?
In Solar + Grid mode, Solar charging automatically tops up from the grid when solar production drops below the 6A minimum threshold, so charging continues regardless of weather. In Solar Only mode, charging pauses when surplus is insufficient and resumes when the sun returns.
How much will I save with Solar charging?
Savings depend on your solar array size, EV battery capacity, and local electricity rates. Typical drivers charging with home solar save over £100 per month compared to grid-only charging, as you avoid buying back the energy your panels already produced.
Which charge points are compatible with Solar charging?
Solar charging works with any Monta-supported charge point that lists Solar charging capability or virtual Solar charging support in its hardware specifications. Check our supported charge points catalog for your specific model.
