Definition of solar battery
1. A solar battery is a device that can be used in a solar power system to store the electricity generated by the solar panels during the day when there is surplus energy on the solar panels. When the solar panels are not able to provide enough power or at night, on cloudy days and during power outages, solar batteries can release the stored energy to power the home, saving us money on our electricity bills and achieving energy independence.
2.When the sunlight hits the solar panel, it will convert the sunlight into direct current, and through the solar controller and solar inverter, the voltage will be converted into the voltage suitable for the solar battery, charging the solar battery, and the solar battery will have a chemical reaction inside, storing energy. We recommend JMHPOWER brand solar batteries, the battery has a long service life and has a long-term warranty, you can also choose JMHPOWER brand solar power system, you can effectively utilize solar energy, saving electricity costs, to deal with emergencies, etc., please contact us if you have any questions.
Solar battery types
There are several types of photovoltaic batteries, including lead-acid batteries, lithium iron phosphate batteries, lithium-ion batteries, liquid current batteries, each battery has different characteristics, as described below:
1. Lithium iron phosphate solar battery
Lithium iron phosphate batteries are preferred as solar cells, mainly because of the long cycle life of lithium iron phosphate batteries, able to use about 10 years, high energy density, lithium iron phosphate batteries can reach 160Wh/kg of single energy density, high security, no structural changes in the charging and discharging process, will not burn and explode, able to quickly charge, the disadvantage is that the cost is higher.
2. Colloidal solar battery
Colloidal batteries for a lead-acid batteries, the method is to add gel in sulfuric acid, so that sulfuric acid into the gel state, with heat diffusion, not easy to warm up, the possibility of thermal runaway is low, colloidal batteries for maintenance-free batteries, do not need frequent maintenance, the disadvantage of colloidal batteries for the internal resistance of the larger, high-current discharge capacity is low.
3. Lead-acid solar battery
There are two types of lead-acid batteries: liquid-filled and sealed. Lead-acid batteries are affordable, highly recyclable, and have a certain degree of reliability, with the drawbacks of a short lifespan, slow charging and discharging, and the need for regular maintenance, and for sealed and gel lead-acid batteries require less maintenance.
4. Lithium-ion solar battery
Lithium-ion battery life than lead-acid batteries are longer, with high energy density, high average output voltage, small self-discharge, no memory effect, the operating temperature of -20 ℃ to 60 ℃, can be quickly charged, the disadvantage is temperature-sensitive, there are certain security issues, recovery of airborne difficulties. (Memory effect refers to the capacity of the battery is reduced for multiple charging)
5. Liquid flow solar battery
Liquid flow battery consists of electric stack unit, electrolyte, electrolyte storage and supply unit, and manage ent and control unit, etc. It is a kind of high-performance battery that utilizes the positive and negative electrolyte separately, and each of them circulates separately, which has high efficiency, long service lifespan and high safety, and the disadvantages are high cost and limited power density.
The best solar battery
1. The best solar battery is lithium iron phosphate battery, in terms of battery life can reach about 10 years. Traditional lead-acid batteries have a service life of 2 to 5 years, and lithium iron phosphate batteries have a battery management system that prevents over-voltage, under-voltage, abnormal temperatures, abnormal currents, etc., maximizing the protection of the battery and prolonging the service life of the battery.
Traditional lead-acid batteries do not have an integrated battery management system, requiring human intervention. On the other hand, lithium iron phosphate batteries are maintenance-free batteries with high safety and stability, while traditional lead-acid batteries require maintenance and are far less safe and stable than lithium iron phosphate batteries.
2. JMHPOWER brand solar battery can meet any of your requirements for batteries, can be effective for the family to use electricity, in areas with high solar radiation, solar battery can effectively store full power, and for the family to use for a whole night with the remaining power.
Conclusion:
Solar batteries are specially designed for solar energy systems, can effectively meet the demand for electricity, we recommend the use of lithium iron phosphate solar batteries, can cope with a variety of unexpected situations.
