Determine the required UPS capacity: Calculate the sum of all load S = S1 + S2 + ...... + Sn Unit: VA. Select UPS capacity ≥S ÷ 0.8 (consider the impact resistance and the need for expansion of the UPS). UPS to determine the required type: according to the load on the output stability, switching time, the output waveform is determined by selecting on-line, line-interactive, backup lifePo4 batteries. Output line UPS stability, transient response capability than the other two strong ability to adapt to non-linear loads is also strong. Some of the more sophisticated equipment and more important requirements for the use of equipment-line UPS. If you are using a generator with a short delay UPS, recommended on-line UPS, because the generator voltage and frequency ordinary poor stability, with back-line interactive and it may not work properly. Some brands of UPS (on-line) don't match with the generator, it will switch to bypass power, to understand clearly the time of purchase. Dete...

Houses with solar that don’t also have energy storage like  home batteries have no way to use the excess electricity generated during the day when the sun is shining and solar energy is in abundance. When households have solar energy they can’t use, it goes back into the power grid.  Often, power companies pay households for giving back the extra power generated by solar, but not as much as they charge for the same amount of electricity later in the day, when people actually need it. Without a home battery, solar customers end up paying extra for the electricity they generated themselves, which is like paying the power company to store the energy for them so they can use it later. Instead of giving more money to the power companies, why not just store it yourself? With a home battery, solar households have this opportunity. This eases the workload of power plants, decreases carbon emissions, and saves money for households with solar at the same time. Taking this into cons...

It has been described as a car battery power stations. Battery life is generally 2 - 3 years, if used and maintained properly, it can be used to more than four years.

UPS is accompanied by the birth of the computer and appears as a computer peripherals, UPS is an energy storage device comprising, as a main element in the inverter, power protection device output voltage frequency stabilization, which can solve the existing power the power, ground voltage, high voltage surges, noise and so on, so that a computer system more secure and reliable. When a user in the selection of UPS, should be determined according to their own requirements of the selection criteria, choose the most suitable use of the UPS, but not the cheapest or most upscale. Large enterprises in the optional UPS uninterruptible power supply should be aware of the following key indicators: 1, UPS uninterruptible power supply and distribution format many large UPS should adopt Three (380V), three (380V) power distribution formats. 2, Isolation transformer. In order to solve the interference load, zero voltage and isolate problems, generally large UPS comes standard with output i...

Smart balancing scooter battery is the main reason for the explosion. Judging from the current situation on the market smart balancing scooter battery used in opinion, most balancing scooter with 18650 lithium batteries, polymer batteries rarely helpful. There are two reasons to make the battery danger: quality problems and abnormal operations. Battery quality problems will be investigated to the battery manufacturer's non-standard operation: the lithium battery manufacturers include liquid injection when the amount of injection fluid does not reach the technical requirements, there are security risks resulting lithium batteries; lithium battery liquid injection operator after sealing the problem is not up to par, resulting in poor performance resulting in ball seal drums and so on. Smart balancing scooter battery is usually mounted on the foot plate above is often stepped on, being kicked, much less than the balance of the scooter with the tablet more frequently. Therefore, th...

In winter, the solar energy storyage battery should take the following conservation measures: Greenhouse overhead storage batteries when not in the house to save more than 0 ℃, should not be placed directly on the ground. Before storing the first external battery clean, add enough liquid electrolyte, adequate electricity, tighten the plug. After a supplementary charge every month, once every two weeks to check the electrolyte level, and refresh immediately insufficient. Thus, the battery can ensure safe winter. Progress liquid volume ratio of water and sulfuric acid electrolyte composition, the higher the content of sulfuric acid in the electrolyte, the electrolyte specific gravity higher, the lower the freezing temperature of the electrolyte. To this end, the country may be to select the appropriate proportion of the electrolyte according to the local winter minimum temperature, to prevent the electrolyte from freezing. Enough electricity to keep the state during the winter, when the ...

Battery Lose Effectiveness Modes Since the plate type, production conditions, there are differences in usage, and ultimately lead to the battery '> reasons for battery failure is also different, back satisfied them, there are several  Lose Effectiveness  modes: 1.Corrosion deformation of the positive electrode plate board gate Alloy currently used on the production of three types of traditional lead-antimony alloy, antimony or ultra-low antimony alloy, lead-calcium. The three cast alloy grid, the battery charging process will be oxidized to lead sulfate and lead dioxide, leading to the loss of the role of supporting the active material of the battery failure; after corrosion due to the formation of lead dioxide layer, of lead alloy to produce stress, the linear grid grow up deformed, and finally the destruction of the whole plate, the active material and grid off poor contact or short circuit at the bus. 2.The positive electrode active material shedding, soft...

Solar power generation into off-grid power systems and grid systems: Off-grid power systems. Mainly consists of solar modules, controller, battery composition, to an AC load, also need to configure AC inverter. DC power generation system is generated through solar modules and grid-connected inverter converts AC power into the electricity grid in line with the requirements of direct access to the public grid after this. And power generation systems have centralized large-scale power plants are generally national grid station, the main feature is the power can be directly delivered to the grid by grid power to the unified deployment of the user. But this power plant investment, long construction period, large area, the development of a relatively large degree of difficulty. The small and decentralized power generation systems, especially BIPV power system, due to the small investment, quick construction, small footprint, large policy support, etc., is the grid of the mainstream. ...

The lithium-ion battery electrolyte material different from the lithium-ion battery is divided into liquid lithium-ion battery (Liquified Lithium-Ion Battery, referred to as LIB) and lithium-ion polymer battery (Polymer Lithium-Ion Battery, referred to as the PLB) with lithium or plastic ion battery (Plastic Lithium ion batteries, referred to as the PLB). Anode and cathode materials used in lithium-ion polymer battery with liquid lithium-ion is the same, divided into cathode material of lithium cobalt oxide, lithium manganese oxide, LifePo4 ternary materials and materials, graphite is extremely negative, the battery works basically consistent. The main difference lies in the different electrolytes, liquid lithium-ion battery using a liquid electrolyte, lithium-ion polymer battery Zeyi solid polymer electrolyte to replace, such polymers can be "dry state", it can be "colloidal" currently most using a polymer gel electrolyte.
