Batteries are a key element of any solar system since they allow to store the excessive energy produced during the day by solar panels so that you can benefit of this stored energy at night. Also, batteries are highly used in RV, Marine, off grid, off-road and van applications. 

For solar systems, 3 types of batteries stand out: Sealed, GEL/AGM and Lithium.

  • Sealed and GEL/AGM batteries are lead-acid batteries which is the most widely used type of rechargeable battery in the industry.
  • AGM are more expensive than sealed batteries but provide longer lifespan, higher storage and are, unlike is counterpart, maintenance free.
  • Lithium batteries provide deeper depth of discharge at 80% and is the best battery technology since they outshine every other type of battery in any fields which explain its high price.
