How Long Will Your Battery Last in a Power Outage?

During a power outage, you will still generate solar energy during the day to power your most needed lights and appliances. Any excess energy goes to the battery and will be used when the system is not producing enough solar energy, such as at night.1

Select the number of batteries below and the lights and appliances you would want to power to determine how long the battery system will last during a power outage. This does not factor any additional backup power you may receive from solar energy produced from your panels.
