Quick Answer
A Level 2 charger may not be the best choice for a small solar system, as it typically requires a high power output to charge quickly, which can be challenging to achieve with a small solar array.
Level 2 Charging Requirements
A Level 2 charger requires a dedicated 240-volt (240V) electrical supply to charge an electric vehicle (EV) at a rate of 19-80 miles per hour. This translates to an input power of 7.2-19.2 kilowatts (kW). A small solar system, on the other hand, typically ranges from 2 to 5 kW in power output.
Solar System Size and Charging Capacity
To charge an EV with a small solar system, you need to consider the charging capacity of the system and the time it takes to charge. A 2 kW solar system, for example, can charge an EV to 80% in around 5-7 hours, while a 5 kW system can do the same in 2-3 hours. Keep in mind that the actual charging time will depend on the efficiency of the solar system, the battery’s state of charge, and other factors.
Practical Considerations
If you still want to use a Level 2 charger with a small solar system, consider the following: (1) Oversize the solar array to account for inefficiencies and ensure reliable charging, (2) Invest in a high-efficiency solar inverter to maximize power output, and (3) Choose an EV with a lower charging power requirement to make the most of your small solar system. Alternatively, consider using a Level 1 charger (120V) or a DC Fast Charger, which can be more suitable for small solar systems and still provide efficient charging.
