The size of the battery bank you’ll need to power your home will depend on a number of factors, including the appliances and devices you want to run and the amount of backup power you want to have available. To get an estimate of the size of the battery bank you’ll need, start by calculating your home’s daily energy usage. Then, add up the wattage of the appliances and devices you want to be able to run during a power outage. Once you have your total daily energy usage, multiply that number by the number of days you want to be able to go without power. This will give you a rough estimate of the size of the battery bank you’ll need. Alternatively, simply contact Chelion and we can set up a consultation to determine the most appropriate battery size and residential storage solution for you.
