Quick Answer
Automatic start generators can work without sunlight by using alternative power sources. Some models can be charged through a 120V AC wall outlet, a 12V DC battery, or an inverter/charger system. This allows the generator to start even when there is no sunlight.
Charging Options for Automatic Start Generators
Automatic start generators can be equipped with multiple charging options, allowing them to start even when there is no sunlight. For example, a 2000-watt generator with an automatic start feature might have a 120V AC wall outlet charging port, a 12V DC battery charging port, or an inverter/charger system connection.
Battery Requirements for Automatic Start Generators
The battery requirements for automatic start generators vary depending on the model and brand. A typical 2000-watt generator might require a 12V DC battery with a capacity of at least 150Ah. However, this can range from 100Ah to 300Ah or more, depending on the specific application and usage. It’s essential to choose a battery that meets the manufacturer’s specifications to ensure reliable operation.
Inverter/Charger System Integration
Some automatic start generators can be integrated with an inverter/charger system, allowing them to charge from a solar panel or other DC power source. This setup involves connecting the generator to the inverter/charger system, which then charges the battery and provides power to the generator when it starts. This setup can be particularly useful for off-grid applications where solar power is the primary source of energy. The system should be designed to meet the generator’s power requirements, taking into account factors such as starting current and runtime.
