This can vary significantly depending on other equipment and how you and your installer decide to design your setup. In most cases, customers choose to have a critical load panel with an automatic transfer switch. This simply means that you select certain circuits that will be kept on when the grid goes down. Most residential customers choose to keep everything online except for high-use items such as their AC/electric dryer/etc. but, as long as you size your capacity correctly, HomeGrid batteries can easily back up your entire home/business. Some inverters on the market, such as Sol-Ark, can automatically switch to critical loads in 4ms.

Yes, but this has to do with the inverter equipment you or your installer has chosen. An inverter such as Sol-Ark can be set to automatically sell back excess solar if the battery is charged and the home isn’t using enough solar power.

If you are on a time-of-use plan, then you pay more for electricity at certain times of the day. This is typically in the evenings, right when electricity usage can be at its highest. Even if you do not have solar, a battery can save you money by charging at night when electricity is the cheapest, and discharging that power for your use when electricity is the most expensive. If paired with solar/wind, this benefit is even more apparent.

You can monitor basic statistics and battery usage on the display. Each of our battery systems has one and you can view battery capacity, health, and other basic information. The inverter of choice will also have a user interface that allows you to view the statistics and functionality of your battery, home, and solar.
