Although they consume a relatively high amount of energy, it is possible to run air conditioners on a battery bank and solar. The question is, how much battery power do you need to run an air conditioner? Well, the process of sizing a battery bank for your air conditioner is pretty simple, and can be divided into 3 steps:
If your device runs on a battery, it’s DC, as all batteries use direct current to function. You might assume that something uses alternating current because you can power it through an outlet or off the grid (which is always AC), but this isn’t the case. When battery-powered devices charge using the grid, the AC is converted to DC.
If you want to run lots of power hungry appliances from the battery during the power cut you’ll need a high-powered battery inverter. When running a conventional on-grid battery system, peaks in power are often met by the grid.
If we use AC to recharge batteries, then the charge will only flow into the battery for a short period, and after that, it will flow out of the battery. The reason behind this is explained by the name alternating current. So AC can't charge the battery, making it not a viable solution.
Batteries are only able to store currents flowing in a single direction. As a result, conventional batteries can only store direct current (DC) rather than alternating current (AC). Although we charge battery-powered devices, like laptops or cell phones, using an outlet that supplies AC power, it’s only possible because a conversion happens.
This means you keep your battery partially full with your emergency electricity. Most people are using home batteries for storing solar electricity, but battery levels can be low in the mornings. The worst thing would be to invest in a back-up battery system and have no stored electricity in the event of a morning power cut!
How Many Batteries Do I Need For a 1000 Watt Inverter?
In RVs and off grid homes, the inverter is connected to the battery bank and uses it power AC appliances and devices. Even in a grid tied setup, you may want to use batteries as a backup power source. So how many should you get?
