solar battery are mainly used in solar off-grid systems and hybrid solar systems. Solar energy is an important step towards sustainable and cost-effective home energy, but solar panels are not able to store energy and utilize solar energy more efficiently. solar battery can store excess energy in batteries and wait until night, cloudy days, or when there is no power. Maintaining solar battery in your daily life can extend the life of the battery. Solar batteries can be categorized according to chemical composition, structure and principle, etc. They can be divided into lead-acid batteries, lithium-ion batteries, nickel-metal hydride batteries and so on according to their chemical composition.
Solar batteries need maintenance, no matter what kind of solar batteries we use, there are different risks to the life and efficiency of the batteries, for example, lithium-ion solar batteries will have thermal runaway of the batteries, bulging of the batteries, batteries can’t be discharged properly, etc. Lead-acid solar batteries will have insufficient electrolyte, leakage of batteries during the night, deformation of the batteries, sulphation and so on. With proper battery maintenance, the risk of accidents will be mitigated and the life of the solar battery will be increased so that the battery can be used for a longer period of time.
There are certain limits to the temperature and storage conditions of solar battery. Maintaining the optimal temperature is conducive to maximizing the life of solar batteries. solar batteries are usually installed in cool, well-ventilated areas to avoid direct sunlight, for solar batteries installed in harsh environments require temperature control systems and insulation materials to achieve stable battery operation, so the temperature and storage conditions are appropriate in order to play the best performance of the battery.
Regular monitoring of the operating status of solar battery is the key to effective maintenance of solar battery, you can monitor the use of batteries, health and cycle times, etc., when the solar battery temperature is too high or too low, the solar battery charging or discharging voltage is abnormal, the solar battery does not work, etc., you can carry out timely maintenance of the solar battery, to maximize the health of the battery and high efficiency.
Battery discharge depth on the impact of the battery, the deeper the discharge depth of the battery, the easier the service life of the battery will shrink, from another aspect is in the discharge curve, the deeper the discharge depth, the voltage and current will be unstable. So we have to adjust the solar battery discharge depth, can be more effective in balancing the solar battery system, so that the solar battery to play the maximum efficiency.
Regular cleaning of solar batterys, such as battery surface corrosion, debris, etc., can improve the energy absorption efficiency of solar batterys and increase the service life of the battery. We personally do not clean solar batterys, there may be leakage of electricity, etc. It is best to contact a professional to ensure personal life and health safety.
5.1 Check whether there is any depression or protrusion in the appearance of the solar battery, which may affect the integrity of the shell and affect the use.
5.2 Check the appearance for cracks or fissures, which can lead to power leakage.
5.3 Check the appearance of the solar battery for any foreign matter or pollution, which may affect the performance of the cell and reduce the efficiency of its use.
5.4 Check the solar battery connection harness insulation, whether there is a phenomenon of breakage, if there is a breakage will have the possibility of power leakage.
5.5 Check whether the solar battery harness connection terminals are connected reliably to improve the performance of the battery.
In addition to external maintenance, solar battery also need to pay attention to internal heat accumulation. If the solar battery is overcharged, it will cause the temperature of the battery to rise, thermal runaway phenomenon, and in serious cases, an explosion may occur. Over-discharging the solar battery will accelerate the aging rate of the battery, and the service life of the solar battery will shrink. Therefore, we need to pay attention to the state of the solar battery in our daily use, avoid overcharging and discharging, so as to keep the solar battery in the best condition.
If it is an ordinary lead-acid solar battery, you need to check the electrolyte level regularly, and you can add appropriate amount of distilled water when the electrolyte level is low. If the overall capacity of the electrolyte is very low, it is necessary to add an appropriate amount of electrolyte. Sealed lead-acid solar battery and lithium-ion solar battery do not need to check the electrolyte and only need daily attention.
