![]() ![]() Warranty: look at battery warranties to understand DoD, production capacity, etc. But some batteries need a lot of expensive modifications, while others work almost out-of-the-boxĭesign: in response to changing consumer preferences, many battery manufacturers now ship their products in aesthetically pleasing encasements that blend well with existing homes Solar-readiness: most storage technologies can be paired with solar PV panels. Consider what’s going to give your client the most bang for their buck It’s similar to how modern computers ship with “500 gigs” of storage even though the operating system and pre-installed programs take up some of that hard drive space.Ĭonfiguration: batteries can be AC- or DC-coupled what’s needed will depend on the installationĬapacity: larger batteries are able to store more solar power – allowing homeowners to offset a larger portion of their energy billsĬost: because of their high price tags, this is a common concern. If a battery can hold 10 kilowatt-hours of solar capacity, a DoD of 75% means that you can’t reliably draw more than 7.5 kilowatt-hours of clean energy. Although poorly suited for off-grid applications, their compact size makes them a favorite among homeowners.Īnother important consideration is the depth of discharge (DoD), which is the percentage of discharged power relative to the battery’s total storage capacity. ![]() Grid-tied DC-coupled solar batteries: These batteries use inverters capable of accepting high voltage loads. Just keep in mind that for grid-tied connections, solar permitting and utility approvals are usually required. The inverter technology is already built in, making these ideal for both new PV installations and retrofits. Grid-tied AC-coupled batteries: This arrangement is more popular for residential storage needs. Off-grid AC-coupled batteries: These systems perform the same basic function as their DC counterparts – but the conversion process happens prior to reaching the batteries themselves. They normally come with built-in inverters to convert direct current (DC) to alternating current (AC) power. Off-grid DC-coupled batteries: This type of system is often used to power both remote properties and recreational vehicles. ![]()
