Weak current College】 【how according to the electrical equipment determine battery capacity?】.

<br> And inverter supporting the battery should be available for the deep-cycle lead-acid storage battery charging and discharging. For a deep discharge function of battery, the power of measurement units generally ampere-hour (AH), which indicates that the .unit of time (usually 20 hours) offers the current value. If the power to 100AH battery that can continuously in 20 hours with the current 5A, ie 20 × 5 = 100. <br> Battery is inverter system extremely important constituent. When users .choose the battery, you should choose the quality and quantity of larger variety, large-capacity battery with a long time, while the power power devices instantly start to provide enough current. For some of the power of the electrical equipment, it is recommended that .the batteries should be 200AH (<1000W), power and large, it is best to use the battery 400AH. <br> How to use electrical appliances to determine battery capacity, the simple way is to place all electrical power, multiplied by the .battery every time charging interval time between uses. <br> Calculation of electric power consumption of the unit is power or VA, following by a filled every day by, for example, specific results are as follows: <br> Load consumes power usage time .(charging) WHr (power × time) <br> TV and VCD115 Watts 3 hours (1 hour per day) 345 <br> Coffee machine 750 Watt 1 hour (every 20 minutes) 750 <br> 800-Watt microwave oven for half .an hour (every 10 minutes) 400 <br> Total 1495 1665 Watts 4.5 hours <br> <br> The WHr is divided by 10, you can convert the WHr-on time (at 30 ° c): 1495 WHr ÷ 10 = .149.5. <br> For the load, a 150 Ah battery can meet your needs. But in this case, the battery will power on, and General battery discharge of the ideal State is 50%, for the load, the user needs a 300 .Ah battery. Battery capacity (AH) is bigger, stronger power supply capacity, excessive discharge of batteries, the less likely. <br> Battery life depends on the depth of discharge, the greater the depth of discharge, less life. When the load .increases battery power should also be increased. So you may need to use more battery. Two batteries joins with battery cathode and anode, cathode and anode joins. This battery capacity will be doubled, and the voltage and a battery voltage. The different manufacturers or .different safety when battery joined together is not desirable, as this will reduce battery life. <br> <br> <br> <br>.
