Due to their affordability, FLA batteries are typically a great option for RE systems, especially for those that need a lot of energy storage. However, FLA batteries do need to be maintained! You can ensure that your system works properly and that your batteries have a long, healthy life by performing routine inspections and maintenance. On the other hand, sealed batteries will be a better choice if you’re employing the deep cycle batteries in a remote location where routine maintenance is not possible. Additionally, sealed batteries can be used in instances where venting is impossible or if there are space restrictions that force you to store your batteries in strange orientations. The best batteries available are lithium-ion ones.
Increased transportability is one of the key benefits of sealed/lithium batteries over FLA batteries. Lithium and sealed deep cycle batteries can be carried by air or freight (weight permitting), but FLA batteries are sometimes categorized as “hazardous products,” which limits the transportation possibilities.
Based on their nominal voltage and (Ah) of storage, all batteries are sized. Battery “groups” are included in classification systems, although manufacturers also frequently offer lists by voltage and ampere-hour capacity.
Except when employing an MPPT charge controller that can take a greater input voltage than the battery bank voltage, the battery bank voltage for an off-grid system must equal that of the solar array.
The sealed, maintenance-free, SMF dry-cell batteries are called AGM (Absorbed Glass Mat) batteries. Wet-cell batteries, commonly known as flooded batteries, are what make up tubular batteries. Both inverter battery configurations have advantages and disadvantages. Batteries that are sealed and maintenance-free are easier to use, require less upkeep, don’t leak, and are unquestionably better for the environment. With a more robust composition, tubular make up for the maintenance hassle by providing better performance and a longer lifespan.
You have the top battery brands available to select from Apex Power Hub, whether you want the tubular battery for more value or the SMF battery type for more ease.
