You must know that AC inverters provide power backup during power cuts. They let you continue using your equipment without worrying about any downtime.
It’s the battery that assures minimal conversion losses because AC inverters don’t generate electricity like gen sets. Gen sets use, or instead consume diesel to generate electricity while inverters depend on stored energy.
Your inverter consumes and stores power from the grid in the battery when the mains are on. The grid power is alternating current (AC), and the batteries store electricity only in the form of direct current (DC).
So the battery has first to convert the AC to DC to get charged, and then store the electricity. It then uses this stored energy to power your equipment during a power outage. Selecting an inverter with the right batteries go a long way at minimizing conversion loss.
It is optimal copper transformers, and not the cheaper aluminum ones in the battery, that reduces AC to DC conversion loss.
As copper is a good conductor of electricity, they cost more, making batteries with copper transformers an expensive choice. However, its minimal conversion losses compensates for its higher price.
Number of hours of backup
The battery capacity is the number of hours your AC power industrial inverters can run. It’s imperative you know how many hours of backup the battery provides in Ah.
While the inverter’s battery voltage is standard at 12or24V, you don’t have much choice. However, you can select the Ah capacity depending on the amount of backup required.
For example, 12V inverter with 100Ah battery gives 2-hour backup while 180Ah battery gives 4-hours backup. Bigger batteries are expensive and take up more space, but they are worth the amount of backup provided.
All this is difficult for the layman to understand. Your Exeltech expert will help you out by selecting the right AC inverters with optimal battery capacity.
