Solar Batteries

Solar batteries store electricity generated by onsite solar power systems for later use, enabling time-shifting of solar generation rather than acting as standalone energy infrastructure. Deployed behind the meter, they are commonly integrated with solar panels and power electronics to improve self-consumption, manage peak demand, and support electrically driven equipment when solar generation is unavailable. They are distinct and different than the batteries used on BESS systems.

Most solar batteries today use advanced lithium-ion chemistries - particularly lithium iron phosphate (LFP) - which provide high cycle life, safety, and efficiency. These systems enable daily self-consumption, backup power during outages, and cost savings through time-of-use energy management.
