How Does The Enphase Battery Function?
The Enphase AC Battery functions as part of a solar energy system in the following way:
Solar Power Generation: Solar panels installed on a residential or commercial property generate direct current (DC) electricity from sunlight.
Inverter: The DC electricity produced by the solar panels is sent to an inverter, which converts it into alternating current (AC) electricity. Enphase microinverters are often used in their systems to optimize the performance of individual solar panels.
Energy Consumption: The AC electricity is used to power the electrical appliances and devices within the property. If the solar panels generate more electricity than is currently being used, the excess electricity can be fed back into the grid or stored in a battery.
Battery Charging: When there’s excess solar electricity being generated and not immediately used, the Enphase AC Battery is charged. The battery stores this surplus energy for use during periods when solar generation is low, such as at night or on cloudy days.
Energy Discharge: When the property’s energy demand exceeds the current solar generation, or when the sun isn’t shining, the stored energy in the Enphase AC Battery is discharged. This helps to provide a continuous supply of electricity to the property, reducing the reliance on grid power and potentially lowering electricity bills.
Monitoring and Control: Enphase’s energy management system allows homeowners to monitor the performance of their solar panels, inverter, and battery. They can track energy production, consumption, and battery status through online platforms or mobile apps. This enables users to make informed decisions about their energy usage and manage their energy storage effectively
When you make the decision to acquire an Enphase battery, you’re not just obtaining a standalone energy storage unit; you’re gaining access to an integrated energy storage management solution. The installation involves three pivotal components:
