Optimized photovoltaic-energy storage system

The storage and optimization of the use of solar energy, which is only available in a limited time frame, requires monitoring and proper energy distribution. The use of two rechargeable groups, one with a smaller capacity and one with a much larger one, allows the charging to take place with less current and thus to reduce the cycles of the battery with the higher capacity. The system includes hardware for measuring energy stored in batteries and momentary generated by photovoltaic energy. With the help of the creation of an optimal energy plan and the possibility of calculating the savings by avoiding the need to purchase the relevant energy from the public network. The lead -acidic batteries and Li -ion batteries are combined for daily charging and discharging. The combination of two sets allows a relatively lower price for capacitance, while significantly increases the lifespan of the batteries.
