An effective solar battery storage system will convert the energy produced by the solar panels and store it as AC power to be used later. The more battery capacity that you have the more it can charge. This means that if you have a large charging system, it will not have a problem charging larger solar systems. This is what occurs when you have a battery storage system:

• Charge – A battery storage system is charged during daylight by clean electricity from solar energy.
• Optimization – An efficient battery software relies on algorithms to generate solar production, utility rate structures, weather patterns, and usage history to improve the stored energy being used.
• Discharge – When there is a high usage of power, this is when the battery storage system will discharge the energy that is needed.

When there is a battery storage system installed, then excess solar electricity is stored so that it doesn’t go back to the grid. When the solar panels create too much electricity than what they need, then the rest of the energy will charge the battery. As confusing as this may sound, it works.
