Company Profile

Why lithium iron phosphate battery？ 1、Lithium battery performance requirements include energy density, power density, cost, life and safety. Energy storage applications have relaxed requirements on energy density and power density of batteries, and more emphasis is placed on reducing the cost of distributing storage power. Energy storage batteries should have low cost and long life, and ensure the safety of battery applications. 2、Lifepo4 battery has become the main choice of energy storage battery due to its excellent safety, long cycle life, abundant metal resources, low cost and environmental protection. 3、The performance of lithium iron phosphate material is close to the theoretical bottleneck, and it is difficult to improve the performance of the material. Low-cost long-cycle lithium iron phosphate cathode materials are currently being developed. Materials currently under development include high pressure solid density, fast charge, high energy density materials (such as lithium ferromanganese phosphate). Selection of cathode materials for energy storage battery Positive electrode material is the most important material cost, accounting for about 55%. Lithium ion batteries are mainly divided into lithium iron phosphate batteries and ternary batteries based on different cathode materials, power batteries have both, and energy storage batteries are almost all lithium iron phosphate batteries in marker.

FAQ

1,Q:Why your quotation is higher than other suppliers? A:In domestic market, the high and low inverter brands are mixed together. There are many low-cost inverter is actually some assembled small unlicensed workshops, it crudely, to reduce costs and use of substandard components for assembly, there is a very big security risk! In order to protect the pro personal and property safety, please do not covet low price, be sure to choose a reliable inverter! .............................................................................................................................................................. 2,Q:How many categories does it have according to the output waveform ? A:Type one: Modified Sine Wave inverter, which uses PWM pulse width modulation to generate modified sine wave. Due to the usage of intelligent dedicated circuit and high power field effect tube, it greatly reduces the power loss and increases the soft-start function, effectively ensuring the reliability of the inverter. If the power quality is not highly demanded, it is able to meet the needs of most electrical equipment. But it still exists 20% harmonic distortion problems when running sophisticated equipment, can also cause high-frequency interference to radio communications equipment. This kind of inverter can meet the basic needs of most of our power, high efficiency, small noise, moderate price, and thus become the mainstream products in the market. Type two: Pure Sine Wave inverter, which adopts isolated coupling circuit design, high efficiency, high stability of the output waveform, high-frequency technology, small in size, suitable for all kinds of load, can be connected to any common electrical devices and inductive load devices (such as refrigerators, electric drill, etc.) without any interference (eg: buzz andTV noise). The output of pure sine wave inverter is the same as the grid tie power we daily used, or even better, because it does not exist grid tie electromagnetic pollution. .............................................................................................................................................................. 3,Q:Is the output voltage of our inverter stable ? A:Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value by a multimeter. Actually the output voltage is quite stable. Here we need make a especial explanation : many customers found it is unstable when using conventional multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only test pure sine waveform and calculate datas. .............................................................................................................................................................. 4,Q:What is a resistive load appliances? A:Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescents, electric fans, video broadcast, small printers, electric mahjong machines, rice cookers etc. All belong to resistive loads. Our modified sine wave inverters can drive them successfully. .............................................................................................................................................................. 5,Q:What is the inductive load appliances? A:It refers to the application of electromagnetic induction’s principle, produced by high-power electrical products, such as motor type, compressors, relays, fluorescent lamps, electric stove, refrigerator, air conditioner, energy saving lamps, pumps, etc. These products’power are far more than the rated power (about 3-7 times) when start. So only pure sine wave inverter is available to them. .............................................................................................................................................................. 6,Q:What should be noticed when installing inverter? A:Put the product in a place where is well ventilate,cool, dry and water-proof. Pls do not stress and do not put foreign objects into the inverter.Rember to turn on the inverter before turn on the appliance.
