Depending on the type, batteries may need to be located inside or outside of your home. A contractor can help you determine where the battery system will be installed to accommodate your available space and system needs.
A contractor can help you figure out the best way to incorporate batteries into your home, including how to size your system and determine the number of batteries needed. You’ll want to consider what you want to power during an outage, and a contractor will look at those appliances, lighting, or priority equipment to decide your power needs.
No, you do not need to have solar installed to install a battery storage system. However, there are several benefits to pairing these systems with a solar system. Yes, you may install a battery that isn’t charged from a solar system. Your battery would charge from the grid and could provide power in the event of an outage.
Installing a battery in your home or business can help you prepare for power outages or extreme weather events. Batteries can provide backup power when the electricity goes out, keeping your lights, small appliances, and medical equipment running. A battery system can replace a fossil fuel emergency generator with a quieter, cleaner alternative. For commercial properties, batteries can help reduce peak demand charges, which can save money for building owners.
Batteries store electricity from the grid or a source of energy (e.g., solar system). During an outage, that stored energy can be accessed to keep lights and appliances functional. If your home has a solar photovoltaic system, the battery can store or be recharged from the energy generated by that system. This can provide even more resiliency in the event of an outage.
