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 battery pack . 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.

Home Batteries Can Save More Money

Image
Houses with solar that don’t also have energy storage like  solar power 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 power storage  at the same time. Taking t

( 48V) Lithium batteries  are flammable devices, mobile phones, scooters and other built-in lithium device, if used improperly, there is always the time of explosion. We have reproduced in movie, show scooter lithium blast. Do lithium produced in the manufacturing process itself is also a problem can not be ignored, because the manufacturing process was defective, it is easy to leave fragments of metal dust, copper and aluminum foil between the positive and negative should be insulated from these scrap battery overheated, will be like the dumplings in boiling water to do the same random thermal motion in the electrolyte, if prolonged exercise, these particles happen to be close to the  lifepo4  battery  positive and negative poles in the middle of the diaphragm can easily cause a short circuit inside, and inside the battery the electrolyte is a flammable liquid, a spark caused by a short circuit in a confined environment can easily lead to electrolyte battery ignition internal comb

Six Ways for Solar Energy Storage Battery Freeze in Winter

Image
In winter, the  solar power batteries  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 batter

Battery Lose Effectiveness Modes
