UPS power host capacity of 10KVA, the battery is 100AH 32 section, the device power if it is: 200W asked the UPS can power how long time, how to count?
According to the information you provide, the battery is 32 12V 100Ah, the load power of 200W; then the UPS power supply time is calculated as follows:
1.UPS battery discharge when there is a protective voltage (that is, the minimum voltage of a single battery) is 10V, then a group of batteries minimum voltage of 32 * 10 = 320V, the inverter efficiency is generally taken 0.9, then the maximum discharge current of the battery Is 200 / 0.9 / 320 = 0.69A; the average discharge current of the battery is 0.69 * 0.8 (correction factor) = 0.55A
2. Discharge rate = 0.55A / 100Ah = 0.005C; according to the battery discharge curve, the corresponding discharge rate of the corresponding discharge time. General lead-acid batteries are 20 hours discharge rate (more than 20 hours on the abnormal discharge, 20 hours after no discharge curve, and also find the corresponding time): the discharge rate of 0.05C can last 20 hours. The above system has a discharge rate of 0.005C for at least 20 hours.
3. General lead-acid batteries do not have such a small discharge rate to discharge, easy to cause the battery depth of discharge damage to the battery. Recommended battery capacity to reduce or increase the load power, improve system efficiency.
The theory is 80 hours. The load is better than half load (4000W) or damage to the battery
200W why do you use 10KVA host? Do not waste ah, Rugao configuration can not change the words, a long time Oh
