If you can’t charge above 80% at 3kw then you have a major problem with your car. Cell balancing does not require high wattage charging.

The issue is not in the car but in hours of sunlight vs battery SOC when the Sun start giving enough energy to charge... If you charge at 3kW it's a slow charge. In winter it means you end up in the "evening" after all "Sun day" at 3kW and still the battery hardly have more than 80%.

IF you charge at let's say 7-10kW than things change...
