Combining Systems with A Battery
Battery & Solar
Integrating Battery and Solar is the best way to maximize your system’s value – allowing you to use solar power day and night. A battery can be integrated with a new or existing solar system.
Since a Battery is an AC coupled solution, it is compatible with all inverter types. To ensure reliable operation during power outages, at least one battery is required for each 7.6 kW AC of solar included in the backup circuit.
A Battery & the Grid
When a battery is installed without solar, it can charge from the grid if in Backup-only or Time-Based Control to support you during grid outages and to help you save money on your electricity bill. When a battery is installed with solar, it will not be able to charge from the grid.
A Battery & Generators
A Battery can be added to a system with a backup generator connected with an external Automatic Transfer Switch (ATS) or a Manual Transfer Switch (MTS).
The Battery is installed between the utility meter and the transfer switch and can charge from solar while the grid is operational. However, a battery and generator are not directly integrated which means a battery does not charge from the generator.
In an outage, a battery responds immediately and provides backup power before the generator can detect the outage. The generator is turned on only when the battery has a low charge, or if loads exceed a battery's maximum output.
When grid power returns, the generator will turn off and a battery can again charge from solar. If a battery is installed with a MTS, manual operation of the switch is required to power the home with the generator.
A Battery & Electric Vehicle Charging
A Battery can provide stored solar energy to your electric vehicle through your home electrical panel. However, there is no direct connection between a battery and your charging equipment.
A Battery & Other Systems
A Battery does not currently work with existing battery systems or other renewable energy sources, such as wind or hydro.
