How to Extend the Life Solar Battery Storage
Author: Source: Datetime: 2016-10-11 10:23:37
Solar battery storage is the 'battery' in the application of solar photovoltaic power generation, the current use of lead-acid maintenance-free batteries, ordinary lead-acid batteries, gel batteries and nickel-cadmium alkaline batteries four. China is currently widely used solar power generator mainly: maintenance-free lead-acid batteries and gel batteries, these two types of battery, because of its inherent "free" maintenance features and less pollution to the environment characteristics, it is suitable for reliable performance solar power supply systems, especially unattended workstations.
Solar Energy Battery Storage Should Have the Following Characteristics
- Good deep cycling capability, with good overcharge and over discharge capacity.
- Long life, a special process design and gel electrolyte to ensure a long-life battery.
- Different applicable environmental requirements, such as high altitude, high temperature, low temperature under different conditions can be used normally the batteries.
- Fast charge and discharge, no memory function
- High energy density
- Good safety performance
During the day the sun light shines on the solar modules, the solar cell module to generate a certain level of DC voltage, light energy is converted to electrical energy, and transmits it to the intelligent controller, through intelligent controller overcharge protection, solar energy components coming delivered to the battery for storage; and the need to have solar power storage solutions, so-called battery that is the storage of chemical energy and emit an electrical energy chemical equipment if necessary.
Solar Energy Storage Batteries Use And Maintenance
A suitable working temperature 15 ~ 20 ℃
Solar energy storage batteries coupling methods are: solar battery positive electrode and a positive electrode, a negative electrode and the negative connection. Such a solar battery power will be doubled, and a solar battery voltage and the voltage of the same. Solar column must not short-circuit the battery poles (meet).
For the new installation or renovation of the first solar power batteries charging, charging once a long time for initial charging, capacity should be rated current for charging 1/10. Before installing the battery must measure the adequacy, such as lack of electricity, on a sunny place the battery to charge more than 8-16 hours with AC or battery fully first, should strictly avoid over discharge charge. When using the AC charging properly, preferably graded charging that are charged in the initial charge with constant high current, charge voltage and charge to a certain time constant after the switch to a conventional constant voltage float mode.
To keep clean the solar energy storage batteries itself. Mounted solar battery pole should be coated with Vaseline to prevent corrosion of the pole.
Configured as a solar battery-line monitoring and management technology, solar storage battery internal resistance online measurement and analysis, to detect defects in the battery, timely maintenance.
Prevent winter freezing burst of solar batteries, avoid direct sunlight in summer, solar storage batteries should be placed in ventilated cold place. TAG: Multi-Storage Reliability Shell Manganese 200MW Ørsted Micro ABB Programs Volvo 65MW Porsche Largest Volkswagen Lease
