Yes. You can power your home or business on Solar energy during the day while your Solar battery is charging. Any excess energy created will then be discharged at night. Provided there is enough battery storage capacity, you can power your home like this for a long time.Battery backup solution is best for facilities in areas with no grid by providing continuous power supply throughout, these includes hotels, lodges, restaurants, camps, and all other hospitality facilities. However, given the expense of battery backup power, we recommend it for critical loads only, especially if you have a fairly reliable power source (utility or other.)
