Introduction

During the day, the Photovoltaic system generates electricity to supply the loads, excess energy is stored by charging the batteries. Accordingly at night, if there is no output generation from the PV, the stored electricity can be released from the batteries to supply any required power loads.
alfanar offers Energy Storage Systems to ensure continuity of energy supply and improve the reliability of the photovoltaic system. The Energy Storage System is built around modular plug and play battery modules that have efficient charging and discharging characteristics.

alfanar Kopp Batteries

Batteries are used in energy storage systems to store the energy generated from the photovoltaic panels during the day for later use. Energy is saved in the batteries in the form of DC energy. The alfanar Kopp Hybrid Inverter converts the DC energy into AC energy. By using these solar batteries you ensure that you can continue to utilize solar power after sundown, when it is cloudy, during a power outage, or during times of peak energy demand. These batteries have efficient charging and discharging characteristics so that they can be used for both residential or commercial properties

Technical specifications:

• Environmentally friendly and safe LiFePO4 batteries
• Highly efficient charging / discharging thanks to high battery voltage
• Very short charging and discharging time with 9 / 6kW
• Simple and short installation time, Plug and Play
• 20kg battery modules for “one-man” assembly
• Flexibly scalable and expandable, 5.7 kWh, 7.6 kWh, 9.6 kWh, 11.5 kWh
