Quick Answer
Level 2 charging with limited sunlight access is possible, but it requires careful planning, specialized equipment, and often a combination of solar and alternative power sources.
Choosing the Right Equipment
For limited sunlight access, focus on Level 2 chargers with high energy efficiency, such as those with DC-DC conversion or bidirectional charging capabilities. These chargers typically have higher peak power ratings (up to 19.2 kW) and can handle more complex power management scenarios. Consider chargers with maximum power point tracking (MPPT) and a wide input voltage range for optimal solar harvesting.
Solar Panel Configuration
When designing solar panel systems for Level 2 charging, prioritize a smaller, higher-wattage panel setup (around 400-600 watts) over a larger, lower-wattage setup. This approach helps to minimize the impact of reduced sunlight exposure and ensures consistent power output. Use a deep cycle battery bank with a minimum capacity of 12 kWh to store excess energy for later use.
Hybrid Charging Strategies
To ensure reliable Level 2 charging with limited sunlight access, consider implementing hybrid charging strategies that combine solar, grid, and/or generator power. For example, use a grid-tied inverter with a battery bank to store excess energy from the grid during off-peak hours and supplement solar power during periods of limited sunlight. This approach can help minimize energy costs and ensure a stable power supply.
