Lithium ion battery manufacturer provides clear steps to ensure the correct set-up and installation of thebatteries in a system.īefore installation, be sure to cut off the grid power and make sure the battery is in the Recommended Base Load number of Lithium ion battery banks (Example) Safety is described in detail in the safe handling documentation of the Lithium ion battery manufacturer. Since a wide variety of chemical substances are used, always follow the manufacturer’s directions for immediate measures and first-aid measures in the event of an accident. Improper handling or conditions leading to improper operation can cause leakage of battery substances and products of decomposition and reactions associated with these, which can cause personal injury and environmental damage. When handled properly and in accordance with the parameters specified by the manufacturer, Lithium batteries are safe during use. Safe handling of Lithium ion batteries is of key importance. This needs to be followed closely, and the warranty validation form needs to be returned, in order for the battery warranty to be valid. Lithium ion battery manufacturers provide detailed set-up document to follow when using their batteries. OTHER CONSIDERATIONS FOR LITHIUM ION BATTERIES: Therefore, to take into account the expected current draw of the inverter, it is recommended that the minimum number of Lithium ion batteries be linked to the site-specific base load as follows: In many cases the original lead-acid battery bank being replaced may have been too small to fully meet requirements and therefore consideration should be given to replacing it with a Lithium ion battery bank with a larger capacity.Ĭurrent Solution Minimum Recommended ReplacementĮxample : When used with Axpert or Infinisolar inverter, a Pylontech Lithium ion battery will deliver 1.5kWh usable energy when discharged at 1.2kW, and at 600W power draw 1.9kWh usable energy can be utilised. So for example, a 150Ah 48V lead acid battery bank comprising 4 x 150Ah batteries and giving an effective 3.6kWh of storage at 50% DoD could realistically be replaced with 2 x 100Ah Lithium ion batteries which provide 3.8kWh storage at 80% DoD. In order to provide the same storage capacity the minimum suggested replacement options, whereby Lithium ion is used to replace the most commonly used 48V lead acid battery banks, are shown in the table below: The Lithium ion battery will have a DOD of 80% up to 90% depending on manufacturer and inverter used, which compares to 50% for typical lead-acid batteries. When considering the size of the of the required Lithium ion battery bank there are two key factors:īoth aspects should be considered and the number of Lithium ion batteries specified should meet at least the minimum required based on both criteria. LEAD ACID PRICE PER kWh LITHIUM ION PRICE PER kWh
Compatible with locally available inverters.Modular design gives the end customers the power of choice.Delivers up to 5kW for 15 seconds with single module (2.4kWh).(Lithium ion battery manufactures guidelines should be followed with all installations).Īdvantages of the Lithium ion battery include: Lithium ion battery systems are designed to protect the cell from abnormal temperature, current, voltage, SoC and SoH. Lithium ion battery systems, are developed with higher degree of safety and improved life cycle. Lithium ion battery manufacturers have highly suitable options for both new systems and for ones that need their lead acid batteries to be replaced. Better maintained voltage during the discharge cycle.Reasons for Lithium ion being selected include: Lithium ion is regularly chosen for new installations or as a suitable replacement for lead-acid batteries which have reached the end of their life in a solar PV storage system. Replace your end of life lead acid batteries with lithium ion.
Save money with lithium ion battery storage, superior efficiency and safer.
